I chose the hotel for the volcano. The volcano, naturally, hid behind a cloud.
There was never much doubt about where I would stay in La Fortuna. Volcanoes are my favourite of all the earth’s extravagances, and Arenal Observatory Lodge had once accommodated the scientists who came to watch this one. The observation decks alone were enough to make me lose my head. Almost. It was difficult to become completely carried away by a summit that declined to appear.
Then I stood on my room’s balcony, surrounded by eucalyptus, exuberant vegetation and a great deal of noisy wildlife, and felt I had arrived in paradise anyway.
The mountain I came for
Arenal stands a little over 1,600 metres above the sea. Central America has much higher volcanoes, but this is one of its most recognisable: a steep, almost symmetrical cone whose reputation was made by its shape and its extraordinary activity. That composed outline is the work of repeated eruptions. Successive lava flows built up the flanks of a mountain that is, in geological terms, still young.
Its earliest known eruptions date back roughly 7,000 years. The event that made modern Arenal famous came on 29 July 1968, when explosions opened new craters on its western flank. Hot avalanches of gas and volcanic debris devastated nearby settlements and killed dozens of people. The beauty of the cone belongs to the same history as its capacity for destruction.
What followed lasted for more than forty-two years. Explosions and lava flows continued through an eruptive period that ended in December 2010, one of the longest in the modern record. There was time for an entire generation to grow up with Arenal in eruption. Scientists came to study it, while travellers arrived to watch incandescent lava against the night. A mountain became the reason for a journey—and, eventually, for the lodge where I was staying.
Arenal remains an active volcano, although the prolonged eruption is over. Its quieter phase had begun before my visit. A stay beside it puts you close to a landscape whose making is unusually recent, where lava has redrawn the slopes within living memory. That is part of the fascination for me: the mountain has a history you can still read on its surface.
A lodge built for watching
Arenal Observatory Lodge stands on a private reserve within Arenal Volcano National Park, and describes itself as the only hotel inside the park. The family’s farm was already here when the boundaries were drawn in 1991.
The family bought an abandoned cattle ranch in 1972, preserved its remaining primary forest and began replanting worn-out pasture. Scientists studying Arenal used the property as a base, and accommodation grew around them. The view came first; the bedrooms followed. I like that the lodge had a reason to be here before anyone began selling it.
The small museum records that volcanic history and the research that brought scientists here. It gives the lodge’s name a literal meaning, and its position beside the mountain a purpose that still makes sense.
The reserve spreads across roughly 350 hectares of forest, gardens and pasture. A stay here gives you time to move between them: to leave the cultivated grounds, follow a trail into the trees and return without a transfer or an appointed departure.
A room facing Arenal
A volcano-facing balcony gives you the freedom to wait. You are already in the right place when the cloud lifts. Mine brought Arenal into the stay even when the summit was out of sight.
It is worth being particular about the room. Standard rooms can face forest, offer a partial volcano view, or look towards the lake from a different part of the estate. Smithsonian rooms are associated with the large windows facing Arenal, but the hotel also lists lake, garden and forest outlooks within that category. Specify the view you want when booking; the name alone does not settle it.
The rooms are spacious and simple. For me, the balcony facing Arenal mattered far more than elaborate furnishings.
The original family house, La Casona, still offers a more economical way to stay, with shared bathrooms and a communal terrace. The separate villas allow families and friends more independence; Forest Villa has two bedrooms, two bathrooms and a kitchen. Since the buildings are scattered across the grounds, choosing a room also means choosing your daily walk—to breakfast, to the pool, back through the garden. Internal transport is available when needed.
Into the forest
The suspension bridge behind the main lodge leads to the lower grounds, where the pool and spa sit beside the forest. Going for a swim begins with a walk through the trees.
From there, the trail network spreads through the reserve. Its 11 kilometres leave room for both an easy wander and a longer walk in the forest. The complimentary morning outing with a naturalist gives names to some of what surrounds you; afterwards, there is a trail map and the freedom to explore at your own pace.
The path to Danta Waterfall draws you down into the river country. Steps descend through the forest to the fall, where water gathers below before continuing through the estate towards Lake Arenal. The descent leaves the long views behind and brings you close to the water. Take walking shoes for the steep steps, especially after rain.
On horseback, I followed the farm tracks out beyond the gardens. The estate opens into grazing land and wooded slopes below Arenal. The open pasture gives the mountain room around it. From here, it belongs to a much larger stretch of country than the framed view from a bedroom suggests.
This is still a working finca, set between the Danta and Agua Caliente rivers. Groves of eucalyptus and Honduran pine grow on land once cleared for cattle, while remnants of primary rainforest have been preserved. The riding trails connect the open grazing land with the planted groves and the rainforest. The surroundings keep changing without your leaving the estate.
For a place chosen for something so large, the Observatory rewards looking closely. Flowering gardens and fruiting bushes bring hummingbirds, toucans and oropendolas within the everyday life of the lodge; you do not have to devote the entire day to a forest expedition. More than 500 bird species have been recorded across the property. Bring binoculars. The volcano can afford to lose your attention for a while.
The Nest takes that attention upwards. Its 146 steps climb through the trees to a platform 28 metres above the ground. At canopy height, the forest has another horizon, opening towards Arenal, Cerro Chato, the lake and the Tilarán mountains. The climb offers a chance to watch birds moving through the treetops, with the country that sustains them spread out beyond.
For a gentler day, an accessible paved path enters the gardens and forest, while a tractor ride visits the working finca on selected days. The separate guided waterfall-and-farm tour includes a tractor return. You can go further into the estate without making every excursion a long walk.
Plantain, eventually
In Costa Rica, fried plantain kept appearing at the edge of my plate. I kept politely leaving it there. Then I finally cut off a piece.
I wanted all the plantain I had failed to eat returned to me immediately.
El Jilguero is a good place to arrive hungry. Breakfast brings Costa Rican coffee, gallo pinto and homemade bread before a day on the trails. Lunch makes room for the casado, the generous everyday meal built around rice and beans, while the kitchen also gives local ingredients a more elaborate treatment: mahi-mahi with passion-fruit sauce, or hearts of palm made into ceviche.
The menus leave room for vegetarians too, from a meat-free casado to gnocchi with vegetables. That range matters when the next restaurant involves a drive. Coming back to the same table needn’t mean ordering the same dinner.
By evening, the attention shifts towards Lake Arenal. The deck and Chato’s Bar give you somewhere to settle for sunset, without having to make another journey out of dinner. The place you have come to see is still with you at the end of the day.
After the trails
After the trails, a swim or a soak in the covered hot tub can take up the rest of the afternoon. Rain matters less under that roof. Natural hot springs are a separate outing elsewhere in the Arenal area.
The Observatory Spa continues that quieter part of the day. A tired-legs massage has a particular logic on a property with this many paths. There are longer deep-tissue, Thai and hot-stone treatments too, alongside coffee scrubs and volcanic-mud wraps. A rain shower need not send everyone back to their rooms.
The longer combinations pair a coffee scrub with deep-tissue massage and a volcanic-clay facial, or a chocolate wrap with massage. I like the balance: enough comfort to make returning from the trails a pleasure, with plenty of reasons to go out again.
The road back to La Fortuna
The road to La Fortuna is the practical cost of all this space. The public approach includes gravel and dirt, and its condition changes with rain and maintenance. A car gives you freedom to dine in town or explore further; the lodge also arranges transfers. When booking an outside tour, specify the Observatory itself, since some operators charge extra to collect guests here. Breakfast is included in the room rate; lunch, dinner and spa treatments are separate.
The lodge’s own reserve and trails are distinct from the separately managed public sectors of the national park. Admission to those sectors, including the old lava-field walks, is additional. Staying inside the park also does not open a route to Arenal’s summit or Cerro Chato’s crater; both remain closed to visitors.
I went to Arenal because I love volcanoes. What I remember with equal affection is being on that balcony, with so much life around me that the absent summit could not spoil it. I had chosen the right place to wait.
