The single best-value Arenal tour is a guided 1968 lava-trail hike combined with an evening at EcoTermales or Tabacón hot springs — about $132 per adult, covering roughly 4 hours of hiking on the actual 1968 flow plus a geothermal soak with dinner. If you only want the volcano, a standalone 1968-trail hike runs about $53. Arenal has not erupted since 2010, so every tour today is about its landscape and geothermal heat, not live lava.
Arenal Volcano: Quick Facts From Our Database
Arenal (database ID 1198) is a 1,670-metre stratovolcano in north-central Costa Rica, roughly 90 km northwest of San José near the town of La Fortuna. Our records from the Smithsonian Global Volcanism Program list 28 eruptive episodes stretching back some 7,000 years, the oldest around 5060 BCE.

One number tour sites never mention: Arenal erupts at one size
We scored every graded eruption in our database. Of Arenal's 25 VEI-rated eruptions, 19 are VEI 4 — a strongly explosive size. It rarely does small, and it has never done a super-eruption. That single-size "fingerprint" is why the 1968 event was so lethal: when Arenal reawakens, it tends to do so violently rather than gently. It puts Arenal in the same erupt-big-or-not-at-all category as Mount Pelée, and it's the reason the summit stays permanently closed even in a quiet decade.
The Best Arenal Volcano Tours in 2026
1. The 1968 Lava-Trail Hike (do this one)
This is the tour to book if you book only one. A naturalist guide walks you across the hardened 1968 lava flow — the same eruption that buried the villages of Tabacón, Pueblo Nuevo and San Luís — with the cone directly overhead. Expect 3–4 hours, moderate footing on loose volcanic rock, and roughly $53 per adult for the guided version (children about $43). The private reserve trails (Arenal 1968) are generally quieter and have better cone views than the national-park sector.
2. Volcanic Hot Springs
The springs around La Fortuna are heated by Arenal's still-hot magmatic plumbing — this is real geothermal energy, not a boiler. Tabacón ($75–110) is the splurge: natural thermal rivers in manicured jungle. EcoTermales ($55–65) is smaller, quieter and reservation-only. Baldi ($30–45) is the big, waterslide-heavy budget option. All three are genuinely volcanic; the difference is crowds and polish.
3. Hanging Bridges & Canopy
Mistico Arenal Hanging Bridges strings 16 bridges through primary rainforest on Arenal's flank — easy walking, excellent for families and wildlife (toucans, sloths, snakes). Budget $50–90 for a guided walk. Zip-line and canopy operators (Sky Adventures) cover the same slopes for adrenaline seekers.
4. Combos & Night Tours
A hike-plus-hot-springs combo (about $132 with transport and dinner) is the best single-day value and the tour most visitors should book. Night wildlife walks ($30–60) trade volcano views for red-eyed tree frogs and stargazing, and pair well with a late soak.

When to Visit Arenal
Here's the thing nobody tells you: Arenal makes its own weather. The cone is frequently cloud-wrapped even in "dry" season, so the reliable move is to be out early. Between 6 and 8 a.m. you have the best odds of a clean summit, any month.
Dry season (Dec–Apr)
Clearest cone views, busiest trails, highest prices. Book hot springs ahead.
Green season (May–Nov)
Lush rainforest, fewer crowds, lower rates. Plan hikes for the morning; rain usually comes after lunch.
Getting to Arenal (La Fortuna)
- From San José: ~3.5 hours by car or shared shuttle (~$55 pp). The most common approach.
- From Monteverde:3–4 hours by road, or the scenic "jeep-boat-jeep" across Lake Arenal (~3 hours, a highlight in itself).
- From Liberia (LIR) airport:~2.5 hours — the fastest flight-in option if you're combining Arenal with Guanacaste beaches.
Arenal's Eruption History: Why the Volcano Went Quiet
For centuries Arenal was so quiet that locals thought it was an ordinary forested hill. That ended violently on July 29, 1968, when a lateral blast tore three new craters into the western flank, devastated about 15 km² (5.8 sq mi), and killed 87 people, burying the villages of Tabacón, Pueblo Nuevo and San Luís.
Rather than falling silent again, Arenal settled into one of the longest continuous eruptions of the 20th century — 42 years of near-constant activity, from 1968 until the lava and glow finally stopped in October 2010. For most of that time it was a reliable nightly spectacle of incandescent rockfalls, which is what built La Fortuna's tourism economy in the first place.
Since 2010 the volcano has been dormant — its longest quiet spell since 1968. OVSICORI keeps it at Alert Level 1, "Calm," and it no longer glows. That's good news for hikers and disappointing for anyone hoping to see live lava; for that, our active-volcanoes tracker points to what's actually erupting right now. Arenal also ranks on our list of most dangerous volcanoes precisely because of that VEI-4 history — worth remembering that today's calm is a pause, not a retirement.
Safety note
The summit and upper cone are permanently closed — no legitimate tour takes you to the top. Stick to marked trails and licensed guides, carry rain gear, and check OVSICORI or our Arenal profile page for the current alert level before you go.
