The Arenal 1968 Volcano Walk takes you across the actual lava fields from Arenal's historic eruption, with trails winding through recovering forests and open lava rock landscapes. It's one of the most unique geological experiences in Costa Rica, and with a naturalist guide, it becomes a fascinating lesson in volcanology, ecology, and succession biology.

The 1968 Eruption Story

On July 29, 1968, Arenal Volcano erupted catastrophically after 400 years of dormancy, destroying the town of Tabacón and reshaping the landscape. Today, the 1968 trails follow the actual path of those lava flows, showing how nature has slowly reclaimed the devastated terrain over decades.

Trail Options

The park offers two main trails: the shorter Coladas trail (1.7 km) through open lava fields with panoramic volcano views, and the longer Bosque trail (3.4 km) through regenerating forest. Both are moderate difficulty with some uneven terrain. A guided walk covers both trails in about 2–3 hours.

Wildlife on the Volcano

Despite the volcanic terrain, these trails support surprising biodiversity. Look for agoutis, coatis, toucans, tanagers, iguanas, and various hummingbird species. Your guide will point out how pioneer plant species colonize the lava rock, creating habitat for animals.

Best Views & Photography Tips

Clear views of Arenal's perfect cone are most common in early morning before clouds build. The open lava fields offer unobstructed views from multiple angles. Sunset tours provide dramatic lighting when weather cooperates.

Frequently Asked Questions

Can you hike to the top of Arenal Volcano?

No. Climbing the cone is prohibited for safety reasons. The guided hikes follow the 1968 lava-flow trails on the volcano's lower flanks, which is where the geology and the views actually are.

How difficult is the 1968 trail?

Moderate. Expect roughly 2 to 3 hours of walking on uneven volcanic rock with some uphill sections. Closed shoes with grip are essential; the surface is loose in places.

Will I see lava?

No — Arenal has been in a resting phase since 2010, so there is no active lava or glowing rock. What you walk on are the solidified flows from the 1968 eruption and later activity.

What time gives the clearest volcano views?

Early morning. The cone is most often cloud-free before roughly 9 AM, after which clouds typically build around the summit.

What should I bring?

Closed hiking shoes, water, sun protection, a light rain jacket, and insect repellent. There is limited shade on the open lava fields.
