1. Arenal Volcano: Costa Rica’s iconic giant
Arenal Volcano, a majestic, near-perfect cone rising to 5,479 feet is one of Costa Rica’s most iconic sights. Although it has been inactive since 2010, it still has a powerful presence, towering over the landscapes of La Fortuna.
As you hike through the park, you’ll move through dense jungle and cross old black lava flows, sometimes feeling the warmth that still rises from the ground. Mist clings to the summit, giving the area an almost mystical atmosphere. At the end of the day, there’s nothing better than soaking in the warm waters of the Tabacón River.

2. Poás Volcano: one of the most visited national parks
Poás Volcano, which is still active, rises to 8,871 feet in the heart of a spectacular national park about 25 miles from the capital, San José. Picture this: a huge crater about 0.6 miles wide and nearly 1,000 feet deep, releasing thick clouds of steam that can rise hundreds of feet into the air. Farther on, an otherworldly blue acidic lake draws the eye.
Because of acid rain, the landscape now has an almost lunar feel. Plan on a good half-day to fully enjoy the volcano and the rest of the park, following the Botos and Escalonia trails.

3. Irazú Volcano: the highest in Costa Rica
At 11,260 feet, Irazú Volcano is the highest volcano in Costa Rica. Local communities have suffered greatly from Irazú’s eruptions, especially in 1963, when ash covered much of their Central Valley. Today, the ascent is a dream for travelers who love hiking in Costa Rica.
Freezing winds, sulfur-tinged air, black sand, acidic green craters, miniature forests… It feels like stepping onto another planet. The park is divided into three areas: the active crater with its colorful lagoon, the inactive Diego de la Haya Fernández crater, and Playa Hermosa. Be prepared, the climate at high elevation can be harsh and unpredictable.

4. Miravalles Volcano: adventure away from the crowds
Still relatively under the radar, Miravalles Volcano offers an authentic experience far from the crowds. To explore it, stop in the villages of Guayabal and Fortuna de Bagaces, an ideal way to discover local culture and have a daily rhythm shaped by nature. After your hike, rest your legs in natural hot springs or volcanic mud baths.
In just two hours, you can cross mountains and forests, take in views over the plains of Guanacaste province, then head to Playa Hermosa or Tamarindo to soak up the sun.

5. Rincón de la Vieja Volcano: Guanacaste’s active giant
Rincón de la Vieja Volcano is one of Costa Rica’s most active volcanoes. Divided into two sectors, this bubbling giant in Guanacaste offers some of Costa Rica's quieter, more rugged trails. In Las Pailas, challenging trails lead to La Cangreja or Escondida waterfalls, or to the smoking crater at Cerro Von Seebach. Along the way, you’ll pass fumaroles, boiling lagoons, mud pools, and hidden waterfalls.
From the Santa María sector, take the Colibrí Trail to reach natural hot springs tucked into a wild, protected landscape.

6. Tenorio Volcano: hikes and hot springs
Located in the national park of the same name, Tenorio Volcano offers fascinating hikes through landscapes that change with the elevation. The hike begins at the foot of a dense rainforest, where birdsong mingles with the movement of playful capuchin monkeys.
On the Lago Las Dantas trail, you’ll enter a mysterious cloud forest, cross hanging bridges, and pass crystal-clear rivers. Here and there, you may spot monkeys, toucans, and colorful butterflies. At the top of the volcano, panoramic views reward every step. To end the day, slip into natural hot springs.

7. Turrialba Volcano: the most active and often erupting
Rising to 10,958 feet, Turrialba Volcano, the most active in Costa Rica, dominates the Central Valley. Known for its spectacular eruptions, it often sends up plumes of smoke and ash, as it did in September 2016, when gas clouds reached more than 9,840 feet in altitude.
Its proximity to San José makes it easy to access. Keep in mind that the park is frequently closed depending on volcanic activity. Even so, Turrialba fascinates travelers who love volcanology and adventure, with its smoking craters and lava fields.

8. Barva Volcano: the sleeping giant
In the heart of Braulio Carrillo National Park, Barva Volcano, at 9,534 feet, is one of Costa Rica’s hidden treasures. With its thick forests and mystical lagoons, this inactive volcano has an almost sacred atmosphere. Less visited than other volcanoes, it offers an authentic immersion in preserved nature.
You’ll cross giant ferns and waterfalls to reach the caldera and its deep blue lakes. Hiking this silent giant reveals the richness of Costa Rica’s biodiversity.

9. Orosí Volcano: the hidden gem with an emerald-green lagoon
Nestled in the Guanacaste volcanic range in northwestern Costa Rica, Orosí Volcano stands out for its perfect conical shape. Inactive for centuries, it is covered in lush vegetation and serves as a sanctuary for a wide variety of birds, reptiles, and small mammals.
To explore the surrounding area, our local agencies can arrange hikes or horseback rides. It’s an authentic experience, far from the beaten path and adapted to your pace.
10. Platanar Volcano: prehistoric lava flows
Platanar Volcano, also known as Congo Volcano, is an inactive volcano located in Juan Castro Blanco National Park, five miles south of Quesada. Covered in dense forest, its western flank features ancient prehistoric lava flows.
Walking across this ocean of folded, blistered black rock is a memorable experience on a Costa Rica tour.
