Costa Rica is famous for its volcanic beauty, but most travelers only ever hear about Arenal, Rincon de la Viaja, or Poás. Hidden behind the fame of these popular giants lie lesser-known treasures—Tenorio, Miravalles, and Barva—volcanoes that are just as stunning, often more peaceful, and completely worth your hiking boots. These are the quiet legends, tucked into cloud forests and geothermal zones, offering unique landscapes and far fewer tourists. If you’re craving raw, immersive nature without the crowds, these are the volcanoes you need to hike.
Tenorio Volcano: Where the River Runs Blue
Location: Guanacaste Province, part of the Tenorio Volcano National Park
Elevation: 6,286 feet (1,916 meters)
Known For: Rio Celeste, waterfalls, and vivid blue volcanic chemistry
Tenorio is more than just a volcano—it’s a place where science becomes magic. Deep in the Guanacaste highlands, Tenorio’s mineral-rich underground fuels one of Costa Rica’s most otherworldly sights: the Rio Celeste, a neon-blue river that looks photoshopped. This isn’t just a hike; it’s a journey into a surreal ecosystem.

Trail Highlights:
Rio Celeste Waterfall: A dramatic cascade plunging into an impossibly blue pool. It’s the postcard shot everyone comes for—and it’s every bit as breathtaking in person.
Laguna Azul: A still, reflective pool glowing with turquoise tones, framed by dense jungle.
Los Teñideros: The spot where two clear rivers meet and transform into Rio Celeste’s electric blue stream—thanks to a rare mix of volcanic minerals and acidity.
Borbollones (Boiling Pools): Natural geothermal vents send bubbles and steam from the earth, giving a glimpse into the volcano’s simmering power.
Hiking Conditions:
The full loop trail is around 3.7 miles (6 km) and takes 3–4 hours, depending on conditions. The trail includes muddy sections, stairs, and uneven terrain, especially during the rainy season. You’ll want sturdy hiking shoes and a sense of wonder. Park hours are typically 8 a.m. to 4 p.m., and it’s recommended to arrive early to beat afternoon rains.
Miravalles Volcano: The Quiet Power Beneath Your Feet
Location: Bagaces, Guanacaste Province
Elevation: 6,654 feet (2,028 meters)
Known For: Geothermal energy, hot springs, and hidden nature hikes
Miravalles is a volcano that works double duty—it fuels energy plants and soothes souls. Its underground reservoirs of steam and heat power geothermal stations, but visitors get to enjoy this power in the form of hot springs, mud baths, and secluded trails. While the summit is not open to the public due to its rugged terrain and geothermal activity, the surrounding area is a treasure trove for hikers looking for something different.
Experience Highlights:
Las Hornillas Geothermal Park: Get up close to bubbling mud pots, natural saunas, and fumaroles. You can slather yourself in warm volcanic mud and rinse off in nearby pools.
Hidden Waterfall Hikes: Trails leading from the geothermal areas into the forest offer glimpses of tropical birds, iguanas, and several hidden cascades.
Natural Spa Vibes: Eco-lodges and private reserves in the area offer luxurious hot spring pools in natural settings with minimal crowds.
Hiking Notes:
While there is no traditional summit hike to Miravalles, the trails around the base offer gentle to moderate hiking, depending on the route. Most of the experiences here are accessible for all skill levels. Guides are highly recommended for accessing private reserves and learning about the geothermal processes in action.
Barva Volcano: The Cloud Forest Keeper
Location: Braulio Carrillo National Park, Heredia Province
Elevation: 9,534 feet (2,906 meters)
Known For: Cloud forests, crater lakes, and solitude
Barva Volcano is the tallest peak in the Central Volcanic Range, yet it’s rarely mentioned in tourist brochures. That’s part of its charm. Hidden within the Porrosatí Sector of Braulio Carrillo National Park, Barva is cloaked in mist and mystery. The forest here is lush, quiet, and alive with biodiversity, making it one of the most peaceful places to hike in Costa Rica.
Why Barva Stands Out:
Laguna Barva: A serene volcanic lake nestled in a crater, surrounded by thick, mossy forest. On misty mornings, it feels like something out of a dream.
Copey and Danta Lakes: Additional crater lakes are accessible via longer trails, adding more challenge and seclusion.
Wildlife Encounters: You might spot tapirs, agoutis, howler monkeys, or even the elusive quetzal if you’re lucky.
Trail Info:
The trail to Laguna Barva is around 5.5 miles (9 km) roundtrip, offering moderate elevation gain and some challenging terrain due to mud and humidity. The area is incredibly well-preserved and often very quiet—you might not see another hiker the entire time. This makes it a perfect escape for nature lovers and birdwatchers.
Access Tips:
The entrance to the Barva sector is through San José de la Montana. The roads can be steep and rough—4×4 vehicles are recommended. You must arrive early as park hours typically end by 3:30 p.m., and rangers strictly enforce closing times.
Why These Volcanoes Deserve a Spot on Your Itinerary
While Arenal’s iconic cone may grace the covers of travel magazines, Costa Rica’s true volcanic magic often lies off the beaten path. Tenorio offers jaw-dropping color and elemental energy. Miravalles invites you to walk where the earth breathes beneath your feet. Barva immerses you in a highland world of mist and wildlife where time seems to stand still.
These are not your average volcano hikes. They’re untouched sanctuaries for the curious traveler, offering authentic connection to Costa Rica’s raw natural energy—without the selfie-stick traffic jams.
