ACI Costa Rica is a non-profit organization founded in 1967, whose main goal is to promote programs of intercultural learning and international volunteer service (IVS) for people from all around of the world, facilitating their experience in social and ecological projects, developing global citizens.

ACI wants to contribute to solidarity and friendship between the different societies of our globalized world, to sustainable human development, and personal growth of our participants.
Our organization is an active full member of the International Cultural Youth Exchange (ICYE), a federation of more than 40 intercultural and IVS organizations located in the five continents. ICYE Headquarters are placed in Berlin, Germany. The federation of ICYE has been recognized as International Peace Messenger by the United Nations.

ACI Costa Rica has developed partnerships with other networks and programs such as: The Committee of Coordination of International Voluntary Service (CCIVS), associate to UNESCO, The Alliance of European Organizations (ALLIANCE), Volunteering Matters from United Kingdom (VM), VolontEUROPE, Weltwärs from the German government, and ERASMUS + from the European Union.
The experiences we promote are mainly focused on incoming and outgoing programs, involving long and short-term periods, for groups and individuals. These programs are managed in cooperation with our local Costa Rican networks, partner organizations and communities such as: The Federation of Social Organizations (FOS) and YO ME UNO from the private initiate, and others.


The sea turtle conservation program is a scientific-based conservation activity in which the organizations involved try to increase the amount of sea turtle hatchings in order to give higher survival rates.
The camps are located within walking distances from the beach. Apart from the sea turtles, you will also have high chances of seeing tropical birds, iguanas and monkeys. The main goal of these projects is to help the recovering of sea turtle populations. The species of sea turtles that you can find on these beaches are: Leatherback, Olive riddle, Hawksbill, Green and Logger Head, depending on which project and season you visit.
Note: ASVO decides, if the volunteer goes to Montezuma project or to Buena Vista!

Situation et loisirs: 

Buena Vista beach is a nesting beach of approximately 2.8 km of length and limited in the north by the blind estuary and in the south by the river Buena Vista, the back of the beach is limited by a system of mangroves, which depend on water from the river and tides, beach slope is low ranging between 3 ° and 4 ° to swell, so the currents are strong which makes it an ideal place for surfing.
Buena Vista is located in Samara Beach on the peninsula of Nicoya, province of Guanacaste, in South Pacific.
As an important detail, to get to the project, you should get to Samara town, then after you should take a taxi to Buena Vista River. Once you are there, you have to cross the river (We recommend you to bring backpacks not suitcases).When the tide is low (in summer time), you can cross the river by waking. When the tide is high, there are people from the project who are going to pick you up with a kayak (you are going to get your pants wet).
There are surf lessons for rent in the project. So if you are interested you can bring money to pay for the lessons and to learn how to surf.

Montezuma beach is located on the peninsula of Nicoya, province of Puntarenas and belongs to the conservation area of Tempisque.
