Arenal, Monteverde and the cloud that never lifts

Arenal Volcano had been considered extinct, or at least thoroughly dormant, for four centuries before it erupted without warning in 1968, killing dozens of people in the villages nearest its base and burying others under ash and rock. What followed was forty-two years of near-continuous activity, lava flows, ash plumes and the occasional larger explosion, that turned Arenal into one of the most consistently active volcanoes in the Americas and, unusually, one of the most visited: its near-perfect conical shape, rising cleanly above the surrounding rainforest and a lake at its base, made it a genuine spectacle even as it remained potentially dangerous. Activity dropped off sharply after 2010, and the volcano has been comparatively quiet since, though it remains monitored rather than declared safe in any permanent sense.

A summit that hides more often than it shows

None of this guarantees a clear view. Arenal's summit is frequently wrapped in cloud, particularly in the wetter months, and even in the dry season a clear, unobstructed look at the cone from base to peak is a matter of timing and luck rather than certainty. Visitors who see it clearly on their first evening should count themselves fortunate rather than assume the mountain will oblige on request.

What the volcano left behind

Even with the mountain itself often obscured, Arenal's legacy is easy to feel rather than see. The nearby town of La Fortuna grew almost entirely around tourism drawn by the volcano's decades of visible activity, and the same underground heat that once powered its eruptions now feeds a scattering of natural and developed hot springs in the surrounding countryside, warmed by contact with rock still hot from the volcanic system below. Soaking in water heated by the same geology that produced forty-two years of eruptions is, for many visitors, a more reliable and considerably more comfortable encounter with Arenal's power than waiting out the cloud for a clear view of the summit itself.

Monteverde, where the cloud is the point

An hour or so away, Monteverde works on the opposite principle: here, the cloud is not an obstacle to the view but the defining feature of the landscape itself. Cloud forest forms at an elevation where moisture-laden air condenses into near-constant mist among the trees, supporting a density of epiphytes, mosses and ferns that a drier forest could never sustain. The reserve grew out of a Quaker community that settled the area in the early 1950s and, working with conservationists in the decades that followed, helped set aside the forest that surrounds it today. The resplendent quetzal, a strikingly coloured bird with a long iridescent tail, is Monteverde's best-known resident, though, like Arenal's summit, actually seeing one is a matter of patience and quiet timing rather than a certainty.

Two ways to see both

The Highlights of Costa Rica tour, run by Explore Worldwide, moves from San José through the Doka coffee estate to Arenal and La Fortuna, then on to Monteverde, before finishing at Carara Biological Reserve and Manuel Antonio National Park on the Pacific coast, with an optional beach extension at the end.

The Best of Costa Rica, run by Travelsphere, follows a broadly similar arc over eleven days, adding time at Tortuguero on the Caribbean coast before crossing to Muelle de San Carlos, Monteverde and Manuel Antonio, giving a wider spread of ecosystems within a single trip.

Going anyway

Neither Arenal's cone nor Monteverde's quetzals come with a promise attached, and it would be dishonest to suggest otherwise. What both places offer regardless of whether the cloud lifts is a landscape shaped entirely by forces, volcanic and atmospheric, that are largely indifferent to visitors' schedules, which is part of what makes them worth the trip in the first place.
