THE ADVENTURE COLLECTIVE® · Independent discovery and booking for outdoor travel
Walk across the 1968 lava flows and into regenerating rainforest for uninterrupted views of Arenal Volcano and Lake Arenal. This 3–4 hour guided hike combines volcanic geology, wildlife spotting, and practical trail advice for a memorable outdoor half-day.
Walk across the 1968 lava flows and into regenerating rainforest for uninterrupted views of Arenal Volcano and Lake Arenal. This 3–4 hour guided hike combines volcanic geology, wildlife spotting, and practical trail advice for a memorable outdoor half-day.
You set off before mid-morning, the heat already rising as the trail threads between blocks of blackened lava and stands of regenerating rainforest. The ground underfoot alternates from sharp volcanic rock to compacted soil; the volcano’s grey cone dominates the skyline while Arenal Lake flashes silver to the south. Birds call from the canopy and occasional steam scents the air — the landscape both raw and recovering.

You set off before mid-morning, the heat already rising as the trail threads between blocks of blackened lava and stands of regenerating rainforest. The ground underfoot alternates from sharp volcanic rock to compacted soil; the volcano’s grey cone dominates the skyline while Arenal Lake flashes silver to the south. Birds call from the canopy and occasional steam scents the air — the landscape both raw and recovering.
On July 29, 1968, Arenal’s long silence ended in a dramatic eruption that reshaped the valley. The 1968 trail follows these relatively recent flows: basaltic rock formations, cooled channels, and pockets where pioneer plants and trees are reclaiming ground. Geologically young, the lava fields give way to older rainforest soils and a varied microclimate that supports toucans, motmots and capuchin monkeys. Local guides blend natural history with cultural context — telling stories of nearby La Fortuna and the farming communities that rebuilt after ash and lava altered life here.
Expect a 3–4 hour guided loop that mixes uneven rock walking with shaded forest sections and several 360° viewpoints of Arenal Volcano and Lake Arenal. Wear sturdy footwear for jagged rock and bring sun and rain protection: weather shifts quickly at this elevation. Carry at least 1–2 liters of water, binoculars for birding and a camera with a protective case for volcanic grit. Guided hikes emphasize Leave No Trace: stick to trails, avoid disturbing regrowth, and keep a respectful distance from wildlife. The reward is immediate — intimate views of a landscape caught between eruption and renewal, and a clear sense of Arenal’s geological power.
moderate.
3–4 hours.
Moderate fitness required: able to walk uneven terrain for several hours and handle short steep sections.
Guided tours typically last 3–4 hours and are rated moderate: expect uneven lava rock, short steep stretches and some forested trails.
Children and active older adults can join if comfortable with uneven terrain; the operator recommends moderate fitness and declines bookings for certain health conditions.
This tour includes a certified naturalistic guide and park entrance; guided hikes are required or strongly recommended in protected areas for safety and context.
Common sights include toucans, motmots, and capuchin monkeys; sightings vary by season and time of day.
Arenal’s dramatic eruption on July 29, 1968 transformed the valley; the flows preserved by the 1968 Trail show fresh basalt deposits and areas where forest has slowly returned.
Trails pass through regenerating zones — stay on marked paths to protect fragile pioneer vegetation and support ongoing reforestation efforts.
Blue Pass by Aventuras Arenal operates guided outdoor trips and adventures with an emphasis on safety, stewardship, and memorable experiences.
