International Internships for Environmental Conservation in Costa Rica

Environmental Conservation Internships in Costa Rica are typically based at natural reserves that are involved in environmental research or sustainable eco-tourism. These reserves have a large focus on preserving the fragile ecosystem in protected areas, parks and foundations - 25% of Costa Rica is environmentally protected land, and this includes its stunning cloud forests, where interns can be based.

Interns should come prepared to assist a small team that works towards monitoring and maintaining plant life in reserves and greenhouses. You’ll be guided by local representatives who are passionate about the environment and conservation, assisting with seasonal tasks. Examples of such tasks can include:

  • Working in greenhouse nurseries, helping to grow new plants and propagate others
  • Helping to organize and run environmental informational workshops for the public
  • Maintenance of public and private gardens
  • Tending to medicinal plants
  • Install research cameras to analyze activity of wildlife such as deer, dantas, tapirs, snakes, and wild cats
  • Assisting in tracking various bird species and insects
  • Caring for butterfly farms
  • Organic gardening
  • Helping to maintain trails

Note that the tasks listed are examples of typical activities. The specific role that your internship will entail will be influenced by season and climate, in addition to the project priorities at the time of your involvement. Come prepared to be flexible and adaptable to conditions and site priorities. It’s important to be aware that conditions can be hot and physically demanding. Interns should be fit, have a genuine interest in environmental sustainability, and enjoy working outside!

Environmental Conservation internships in Costa Rica are suitable for participants looking for an introductory experience. Placements do not typically include research components but are rather focused on the day-to-day management, upkeep and operation of sustainable eco-tourism reserves. Long-term participants have increased opportunity to further develop their understanding and proactively initiate independent research. However, the placements themselves are not inclined to be intensively focused on data collection and research. If you have specific course credit requirements for an Environmental Conservation internship experience or would like the opportunity to be involved with research and data collection, please speak to the Intern Abroad HQ team for guidance and recommendations.

In all cases, interns should expect that the first week of your experience will focus on settling in and gaining some introductory knowledge, as you will not “hit the ground running”. Rather, you should start with learning about the placement to gain an understanding of what you can build upon, develop, learn, and contribute. Ensure that you ask questions and provide feedback during the introductory period, so that your supervisor understands how you’re progressing. This will help them to better understand important details, such as how quickly you learn, what you find challenging, what you find interesting, etc.

Understand and expect that individual internship experiences vary, as the specific placement that you’re assigned will depend on review of your resume and your current level of studies and experience. Therefore, if you’re at a more introductory level, you should reasonably expect a more introductory internship. Likewise, if you’re interning for a shorter duration, you will have a different experience from someone who is interning for a longer duration. Placement preferences are considered but always subject to availability.

What recent interns said about their experience

Sarah Waldner
November 2023

I enjoyed everything - the nature, the animals, the exercises, my host family and all the trips I did. Because of that I gained personal growth and learned new skills.

Ava Urquidez
June 2023

I interned in environmental conservation in Costa Rica for two weeks and learned many valuable skills and lessons. I helped with daily tasks such as feeding butterflies, hummingbirds, and cleaning the trails. I also worked on long-term tasks such as planting trees, releasing new butterflies into a second mariposario, and helped promote the beautiful nature preserve. I helped this organization spread awareness of the local animals and plants in Costa Rica to visitors and aided in the maintenance of the beauty of this biodiversity.

This internship helped me get out of the rut and headspace that I was in back in my regular job. I felt extremely stuck and unmotivated prior to experiencing this; and now I feel as though I can do anything and go anywhere with confidence. This experience has taught me a lot about myself and my ability to adapt into any new situation. I really appreciate the opportunity that this company has given me, in that regard. With this experience, I can take the confidence I gained and take it into any new career that I may choose in the future. I could not have gotten more lucky with my home placement and accommodation. I always felt extremely safe and welcomed into my home from the first day I arrived.

Two years ago I started my Environmental Conservation internship in Costa Rica. I still miss everyone I met there and the country. It is a big part of my story and has contributed to where I am now. My biggest challenge and fear was the language barrier. As a non-Spanish speaker, I taught myself as much as I could so I could get by, but, during my time there, I formed genuine connections with people who spoke a different language. We bonded over humor, shared interests, and spending time together. It taught me that communication transcends words - it’s about understanding and shared experiences. Costa Ricans welcomed me as family, into their world, sharing their culture, food, and stories. It felt less like an internship and more like gaining a second family. It broadened my perspective on life and the value of community bonds. One of the most impactful realizations was discovering my capacity to handle tough situations. Traveling to a country on my own was intimidating. Still, with support from others and my own resilience, it was a valuable and impactful experience that revealed so much about myself and my strengths. The things I learned about myself have helped guide my decisions and have led me to where I am today. If you’re considering an internship like this, my recommendation is simple: Go for it. Treasure the connections you’ll build- they’re the true gems of the experience. Keep an open mind, seize every opportunity that comes your way, and push yourself beyond your comfort zone. Trust me, the growth you’ll experience is worth every moment. An environmental conservation internship isn’t just about the work - it’s a transformative journey that reshapes your perspective in ways you never imagined.

From the moment I was preparing for my internship to the moment I took the plane back home I was submerging myself in the Tico culture. It was indeed a dream come true. The beauty and purity of the forest was indeed breath-taking. The family I was staying with was also very sweet and loving. I had delicious food every day. I only wish I had stayed longer. Dare to dream and make your dreams a reality!!

James Wright
March 2019

I feel coming from Hong Kong means I have a limited perspective on environmental education and sustainability, and having experienced this Environmental Conservation internship in Costa Rica, I feel more equipped to explore what I am interested in and who I define myself as a person. What I learnt from the experience has encouraged me but also opened my eyes. Seeing how the scientific world works within the context of a cloud forest research station has taught me that progress often comes through slow and continuous work seldom with major breakthroughs being made. I feel more knowledgeable now that I have worked in this incredibly unique ecosystem, working to ensure that others can enjoy this natural marvel is also inspiring for my own interests. After this internship, I intend to use this experience as a part of my university application; in particular using the conservation internship placement as a case study for sustainable tourism.

Spanish lessons

Internships in Costa Rica require interns to have varying levels of Spanish language proficiency, from either a confident level of basic Spanish to a more developed grasp of intermediate language skills. The definition of having basic Spanish skills (Level A2) includes the ability to exchange brief information with questions and answers, use and understand simple language in daily situations and cultural aspects.

Keep in mind that despite you level of proficiency, a language barrier can still be encountered to a certain extent. Interns should be prepared for the very natural and normal frustration of not always understanding what is being said around them. Most interns are able to have a successful internship experience and it is essential to come prepared and willing to surmount a language barrier, as opposed to being intimidated by it.

We strongly recommend that all interns take advantage of the affordable language lessons offered exclusively to Intern Abroad HQ participants by our host organization in Costa Rica. These can be arranged directly with the local team once registered for the program (ask about online Skype lessons) or at the orientation in-country. Language lessons are tailored to each individual’s current level of Spanish and classes run from Monday through to Friday.

Weekends and travel

During the weekends, free time is available to relax, engage in tourism activities and explore other parts of Costa Rica. The program is based in the canton of San Ramon, in Alajuela Province. This is 55 km/34 mi northeast of Puntarenas (the nearest coastal town), 58 km/36 mi from the capital city of San Jose, and 31 km/19 mi from Juan Santamaría International Airport. The Pan-American Highway is easily accessible to the south and a northern route provides direct access to the popular tourism destination of Volcan Arenal.

Popular tourist attractions in and around the Alajuela Province include visiting Poás Volcano National Park, Arenal Volcano National Park, Los Ángeles Cloud Forest and La Paz Waterfall Gardens. Within the city of San Jose, there are various museums and galleries, such as the Precolumbian Gold Museum, Jade Museum, National Museum, Museum of Contemporary Art and Design - just to name a few!

Our local team in Costa Rica are also able to assist interns with trip bookings, to experience more of the country. These can be coordinated directly once you’ve registered to confirm your internship program. Options include:

  • Tortuga Island: This sightseeing full-day trip includes return transportation from local pick-up points, guides, snacks and entertainment, catamaran tour, and lunch in Tortuga Island. Located within the Gulf of Nicoya, Tortuga Island is a paradise archipelago which has maintained the Ecological Blue Flag status for more than twelve years. The turquoise waters are beautiful to swim in and the trip is not to be missed while you’re exploring the coasts!

  • Poás Volcano National Park, Doka Coffee Tour and La Paz Waterfall Garden: This full day excursion covers some of the region’s highlights. You’ll want to bring your camera and comfortable walking shoes for the three adventures, all across different eco-systems. Within La Paz Waterfall Garden, you’ll have a great opportunity to check out some of the amazing wildlife. There’s a hummingbird garden, serpentarium, aviaries, butterfly garden and tropical frog exhibit.

  • San Luis Canopy Tour: This tour departs from San Ramon and only takes half a day. Enjoy views of the Cataraticas River, bring comfortable clothing and a sense of adventure! There are 12 cables on this zip-line tour, with lengths from 56 to 550 meters, connected across 18 platforms. You’ll also get to experience the Tarzan swing and Superman cable - woohoo!

Arrival and Orientation

Internships in Costa Rica begin every Monday. Exceptions may be made to this when start dates are shifted to avoid public holiday disruptions or closed when the program has already reached capacity. The minimum duration requirement is 2 weeks up to a maximum duration of 24 weeks.

Airport pick up and accommodation are included in the Program Fee. The accommodation is covered from the Sunday night before the Monday start date - interns are required to arrive no later than the Sunday before their Monday start date, as all orientations are held on Mondays. If arriving earlier than this date, interns will be required to cover the cost of an “out of hours” airport pick up.

The typical port of entry is the Juan Santamaría International Airport (SJO). If you are planning to spend time independently in Costa Rica prior to your internship and will not require an airport pick up, we can discuss alternative arrival logistics with you.

Upon arrival, interns will be met, greeted, and transferred to the accommodation. The last night of the accommodation is the Saturday night of the final week, leaving interns free to depart on Sunday. Extra nights of accommodation can be arranged in advance, if requested, and are subject to availability.

Orientation covers important details for your internship, including introductions, information about culture, customs, rules, expectations, safety, language lessons, cultural excursions, and more. Your specific internship placement orientation will follow the general orientation, as you’ll be shown how to travel to and from your internship and be introduced to the team you’ll be joining.

Please note that all participants are advised not to book flights until they have first registered to confirm their internship placement.

Accommodation and WiFi

All interns in Costa Rica are accommodated in various homestay accommodations. Interns are matched to an appropriate host family, taking into consideration convenient proximity to their internship placement. Typical host families in Costa Rica usually comprise of two parents and children or a single parent with children (the ages of a host family’s children can range from young and still living at home, to adults living independently). There are usually 1 - 2 bedrooms in most home-stays and everyone has their own bedroom (unless special requests are made in advance to share with a friend or partner). Bathrooms are shared. Living is comfortable and home-stays offer electricity, running water and western bathrooms. However, showers can be low pressure and unheated/tepid. WiFi is provided in most of the home-stays but it is important to note that it is not guaranteed.

Accommodation upgrades are available at an additional cost, for those who would prefer more independent accommodation and social interaction with other travelers. Interns who have confirmed their participation may opt to arrange hostel accommodation, in either a dorm (sharing a room with 4-8 beds) or a private room. Dormitories provide lockers, so that guests may securely store their personal items. Bathrooms are typically shared. Amenities include WiFi and a common area for guest use. Please note that hostel accommodation is subject to availability (depending on the location of your internship) and includes daily breakfast only. Interns who are interested in arranging an accommodation upgrade are welcome to speak with their Internship Program Manager for more information.

Please note that the accommodation pictured in the photo gallery of this webpage is provided as an example. Since we work with more than one option for homestay accommodation, the exact accommodation that you’re assigned may differ from the photos. However, you can expect a similar standard and similar amenities, to what is shown.


Internships in Costa Rica include two meals per day, served at the home stay. A typical Costa Rican breakfast is provided and may consist of bread, spreads, fruit and eggs accompanied with tea or coffee. Dinner commonly consists of meat (often chicken), soups, pastas, starches and vegetables. Please be sure to let us know of any specific dietary requirements that you have in advance, so that we may ensure your hosts are aware and make recommendations accordingly.
