June is one of the most unique months of the year in Costa Rica. It is not defined by massive festivals, but rather by a unique combination of environmental dates, cultural traditions, live events, and landscapes that transform completely with the arrival of the green season. For those living in the country or visiting during this time, June has much more to offer than it may seem at first glance.
June 5 — World Environment Day
On June 5, Costa Rica actively joins the celebration of World Environment Day, a globally coordinated date that takes on a very concrete meaning here. Municipalities, schools, environmental organizations and local communities organize reforestation campaigns, river, beach and park cleanups, workshops in schools, and educational activities in national parks throughout the week.
This participation is not symbolic: cantons such as Montes de Oca, Heredia, Escazú, Cartago and Liberia often coordinate public activities where anyone can participate without prior registration. It is an excellent opportunity to connect with the local community and Costa Rica’s natural environment in a different way.
June 13 — Planet Gamer | National Stadium, San José
For video game and geek culture enthusiasts, Planet Gamer is one of the most anticipated events of the year. The convention takes place at the National Stadium in San José starting at 10:00 a.m. and brings together tournaments, exhibitions, merchandising, cosplay and everything related to the gaming universe. It has become an increasingly important part of Costa Rica’s entertainment calendar.
June 13 and 14 — Ingrid Rosario in Concert | Teatro Popular Melico Salazar, San José
The Teatro Popular Melico Salazar will host two performances by Ingrid Rosario, one of the most recognized voices in gospel and contemporary Christian music in Latin America. Performances are scheduled for Saturday the 13th at 8:00 p.m. and Sunday the 14th at 4:00 p.m.
The event combines high-level live music with an intimate atmosphere inside one of the country’s most iconic theaters.
June 15 — National Tree Day
Costa Rica officially celebrates National Tree Day on June 15, a commemoration established in 1915 by President Alfredo González Flores through Executive Decree No. 14. This makes it one of the country’s earliest environmental laws and one of the oldest in the Americas.
On this day, schools, municipalities and local communities across the country organize tree planting campaigns, awareness activities and reforestation projects. Parks and urban green spaces become especially active as residents of all ages participate directly in caring for the environment.
More than a school celebration, it reflects the deep connection between Costa Rican national identity and nature.
June 19 to 21 — Cacao Vivo | National Stadium, San José
For three days, the National Stadium becomes the meeting point for lovers of cacao and Costa Rican artisanal chocolate.
Cacao Vivo is an event that combines tastings, talks about cacao production, local entrepreneurship, gastronomy and family-friendly activities. Costa Rica has an important cacao tradition, especially in Limón and the Caribbean region, and this event offers a direct window into that culture.
The event opens daily at 10:00 a.m.
June 28 — Festival of Costa Rica’s UNESCO World Heritage Sites | San José
The Ministry of Culture and Youth organizes this festival dedicated to Costa Rican sites recognized as World Heritage Sites.
The celebration seeks to reconnect the public with the history and universal value of these places through artistic, educational and cultural outreach activities. It is an ideal occasion to rediscover the country’s rich heritage.
June 28 — Music at the Museum: dedicated to the Environment | National Museum, San José
The National Museum’s monthly Music at the Museum series closes June with a special concert dedicated to the environment.
These free concerts, held in a unique historical setting, are among the most appreciated cultural events in San José. The combination of live music, the atmosphere of the National Museum and the environmental theme makes this edition particularly meaningful.
The landscape at its greenest: rivers and waterfalls at peak flow
June does not have an official event here, but it does bring a very visible natural phenomenon throughout the country. With the arrival of the green season, Costa Rica’s landscapes change dramatically.
Waterfalls become fuller and more powerful during the rainy season, which runs from May to November.
It is the perfect time to visit places such as Catarata del Toro in Bajos del Toro, one of the country’s most impressive waterfalls, dropping nearly 90 meters into an extinct volcanic crater surrounded by cloud forest.
Also worth visiting are Llanos de Cortés in Guanacaste, known for being one of the country’s most accessible and photogenic waterfalls, and La Paz Waterfalls in Alajuela, part of a private ecological reserve featuring multiple cascading falls.
For nature lovers and photographers, June offers national parks with fewer tourists, greater biological activity and a level of greenery unlike any other time of the year.
