Hiking in Volcano Arenal National Park in Costa Rica: our practical guide
Is the Arenal hike difficult?
The difficulty level varies significantly depending on which trail you choose at Arenal Volcano National Park. Most paths offer a mix of flat terrain and moderate inclines, making them accessible for people with basic fitness levels.
The main challenges come from uneven volcanic terrain and Costa Rica’s humid climate. Trails near Las Coladas feature rocky sections that demand proper footwear and careful footing. For newcomers to hiking or families with young children, the Peninsula sector provides paved walkways with gentler slopes. More experienced hikers can tackle the challenging routes through primary rainforest, where steep climbs lead to remarkable viewpoints.
Remember to bring plenty of water and take regular breaks—the tropical heat can make even easier trails feel more demanding.
Can you hike around Arenal volcano lava flow and is it worth it?
For safety reasons, all hiking trails around Arenal Volcano are restricted to the areas at the base. The top of the volcano occasionally emits toxic gases and hot steam clouds near its summit.
How to get to Arenal volcano from La Fortuna?
Downtown La Fortuna is 15 kilometers from Arenal Volcano National Park. Visitors have several options to reach the site.
- Shuttle services depart every hour from the central square, with a journey of about 25 minutes for $20 round-trip.
- Cyclists will appreciate the route along a hilly road offering spectacular views of the volcano. Mountain bike rentals are available downtown starting at $15 per day, providing an eco-friendly and sporty way to enjoy the landscapes!
Is Arenal volcano active since its last eruption?
Its last major eruptive phase ended in 2010, marking the end of a spectacular 42-year period. Smoke rises from its summit, indicating continued underground activity. Scientists at the Volcano Observatory monitor it daily.
Today, volcanic manifestations are limited to hot springs and steam emissions, classifying Arenal as a dormant volcano. However, volcanologists believe that this dormancy is only temporary. Magma continues to circulate deep underground, feeding the many hot springs for which the region is famous.
When to visit Arenal volcano?
The dry season, from December to April, is the ideal time to visit. Clear days maximise your chances of admiring its majestic summit, especially early in the morning before 10:00. November and May are also good alternatives, with fewer tourists and more affordable prices.
Bear in mind, however, that in this microclimate, conditions can change from one minute to the next. Your chance could be gone at a moment’s notice!
Which Arenal volcano hike tour is best?
Whichever trail you choose, the great news is that they converge in the middle, leading you to the same viewpoints. At the Lava Flow Summit, the highest point, you can typically enjoy a breathtaking view of Arenal Volcano.
- Colada Trail: Also called “The Flow,” this 4 km (2.4 miles) trail is a bit shorter but can be intense at times. It offers the best views of the dramatic lava flows, making it an unforgettable adventure for those seeking a more demanding route.
- Bosque Trail: Known as “The Forest Trail,” this 4.7 km (3 miles) path takes you on an exciting journey from open fields into the heart of the lush forest, before climbing to the lava fields and a stunning viewpoint. While it offers a moderate-to-challenging hike with some steep sections and rocky terrain, the reward is well worth the effort.
Sendero Colada 1968 trail: how long and how strenuous is it?
The beginning of the trail is relatively flat and passes through a forest. It becomes rockier as it approaches the lava flows, where solidified black volcanic rocks and debris make the terrain more challenging. Over the years, nature has reclaimed the land, with trees, shrubs, and even some flowers emerging among the volcanic rocks.
The Bosque Trail in Arenal Volcano National Park is a lively adventure for wildlife lovers! As you hike, you’ll spot vibrant butterflies, busy leafcutter ants, blue bumble bees, and a chorus of colorful birds.
The highlight of this loop, the Lava Flow Summit, offers breathtaking views of Costa Rica’s generous landscape. Facing you is the majestic Arenal Volcano; turning around reveals Lake Arenal now Costa Rica’s largest lake, surrounded by mountains.
- Tips: Plan a walk on a clear day to enjoy the views and wear suitable footwear for the uneven terrain.
- Entrance fee: Roughly $25 USD per person.
- Duration: Average 1 hour 24 minutes.
Enjoying La Fortuna’s waterfall and hot springs
Thanks to Arenal volcano’s geothermal energy, the region is brimming with natural hot springs, making it a haven for relaxation. While many establishments feature carefully curated thermal baths, adventurous travelers are drawn to a free, untamed alternative: a natural thermal river near Tabacón Hot Springs. Framed by lush vegetation, this river invites visitors to unwind in a setting that feels like a hidden jungle sanctuary.
Reaching the natural pools requires scaling slippery rocks—careful footing is crucial, but friendly locals are often on hand to lend a helping hand. Once nestled between the stones, the river’s soothing warmth and gentle current melt away tension as the verdant canopy above whispers stories of the rainforest.
The area offers even more natural marvels. A trek leads to the beautiful waterfall La Fortuna, the expansive national park with its commanding views of the Arenal volcano, and enchanting walks through the tropical forest at canopy level.
- How to get there: From La Fortuna, cross the bridge and go past the Tabacon Hotel. Park on the side of the road, cross the yellow barrier and go under the bridge to reach the river.
- Tips: Wear a swimsuit under your clothes and bring nothing of value.
The hot springs are a magical retreat in any weather—even under the Arenal volcano region’s frequent rain, which adds a refreshing touch to the experience. Striking the perfect balance between relaxation and adventure, these thermal waters are the best place to explore La Fortuna’s breathtaking natural wonders.
