Things to Do in La Fortuna

Guided Tours, Adventures, and Top Activities Led by Locals

Volcano, Waterfall, Blue River — The Arenal Shortlist

We plan La Fortuna trips the same way every time: work outward from the volcano. Everything worth doing sits within about two hours of town, and the mistake we watch people make is spreading five attractions across two days and spending most of it in a van. Three days is comfortable. Two is fine if you’re ruthless. What follows is the order we actually recommend to guests, with the practical detail that decides whether a day works — the step count, the entry cap, the drive time, the hour of day.

Quick Takeaways

  • The anchor: Arenal Volcano National Park drew 141,145 visits in 2024, ninth-highest of Costa Rica’s protected areas.
  • Two waterfalls, two moods: La Fortuna Waterfall is 70 meters and 530 steps down. Río Celeste is a two-hour drive and 5.5 km round trip.
  • The lava walk is next door: the 1968 Trail sits on a private reserve beside the park, with its own ticket.
  • The overlooked half: Lake Arenal covers 87.8 km², and boats leave El Castillo pier hourly from 9:00.
  • Rain isn’t a season here: the Zona Norte gets rain all year, so pick activities by hour, not by month.

The Volcano Sets the Shape of Everything Else

Start at the volcano. It orients you, and it’s genuinely the busiest thing here: SINAC recorded 141,145 visits in 2024, the ninth most-visited protected area in the country (SINAC, Informe SEMEC 2024). Here’s what catches people out. The lava walk everyone pictures isn’t in the public park — the 1968 Trail runs on a private reserve beside it, and our 3.5-hour guided Arenal Volcano 1968 Trail Hike covers that entrance, the guide, transport, water and a snack. Public park tickets are separate, bought at the park’s own gate. About 1.5 hours of it is on your feet, over loose gravel and old lava boulders. Go in the morning. The summit clouds over most afternoons.

Lake Arenal Is the Half Most Itineraries Miss

The lake is a working reservoir, not a scenic pond. Dammed for hydroelectricity, it covers 87.8 km² and runs wide enough that the far shore reads as weather rather than land. Early is the move: calm water, a long open view of the volcano from the surface, and less wind than you’ll get after lunch. Boats leave the El Castillo pier hourly from 9:00 to 14:00, run a full hour, and include your parking and your entry to the recreation area the pier sits inside. Take the 9:00. Birders do, and the cone is likeliest to be clear of cloud before noon. Or take the Arenal Lake Flexi-Pass: boat ride, Peninsula Trail and a kayak in one 4-hour self-guided session.

Rainforest From Above and at River Level

Two very different rainforest days, and most guests want both. Mistico Arenal Hanging Bridges runs 16 bridges across roughly 3.2 km of trail through a 250-hectare reserve, six of them tall enough to put you level with the canopy. Paved paths link them, so you’re walking, not scrambling. The river-level version is the Peñas Blancas safari float: 1.5 to 2 hours on the water, no paddling, no experience needed. Howler monkeys, sloths, herons, iguanas and a lot of smaller birds work those banks. It ends with a homemade treat and seasonal juice from Doña Mila and her family. Young families pick the float.

How We Sequence Three Days

Volcano and hanging bridges on day one, waterfall and a float on day two, Río Celeste on day three — because the long drive is easier once you’ve acclimated. Now the weather. The Instituto Meteorológico Nacional classifies this subregion as Caribbean-regime with no dry season: rain falls all year, thinning slightly in February, March and October, averaging around 3,100 mm across roughly 225 rain-days (IMN). Don’t plan around a dry month. Plan around mornings, which are consistently clearer, and keep the indoor-ish options — chocolate, lunch, the lake crossing — for afternoons.

Frequently Asked Questions

How many days do you need in La Fortuna?

Three is comfortable and lets you include Río Celeste without rushing. Two works if you skip the long drives and stay inside the volcano–waterfall–lake triangle.

What is the best time of year to visit Arenal?

There’s no dry season in this part of Costa Rica. The IMN records rain year-round with slightly less in February, March and October, so mornings matter more than months.

Is Arenal Volcano still active?

It’s monitored and classified as active, but the eruptive period that started in 1968 ended in December 2010. Nobody is seeing lava today.

Can you swim in Río Celeste?

Not inside Tenorio Volcano National Park — SINAC prohibits entering the water there. Our full-day trip ends the hike, leaves the park, and stops for a swim in the same river at a private spot before lunch.

Is the 1968 Trail inside Arenal Volcano National Park?

No. It’s a private reserve next to the park, with its own entrance, which our guided hike includes. The park’s public trails are ticketed separately, at the park.

Plan It With People Who Live Here

Ordering these days matters more than choosing them. Most visitors get the list right and the sequence wrong, then lose a morning to a van because two stops sat on opposite roads. We build this week after week from an office 400 meters south of the Polideportivo — including the unglamorous parts, like which trail turns to soup after rain. Send us three things. Arrival day, departure day, and the two you refuse to miss.
