Arenal Volcano National Park [Zip-lining, white-water rafting, mountain biking & hiking]

  • Alajuela Province, Costa Rica

Last updated: 05 April, 2024

For just over forty years Arenal was one of the world’s safest active volcanoes to visit – a rumbling cone set in lush forest, spewing out lava that glowed red in the night.

Today, Arenal sleeps but remains truly spectacular – oozing hot rivers and springs, with a near-perfect cone, fuming puffs of gas, and shrouded in black ash. On its slopes, lush forest fringes crumbling, congealed lava fields, and the trees are rich in wildlife – including peccaries, ocelots and capuchin monkeys.

The forests are beautiful, cut with numerous wildlife trails and dripping with waterfalls. There are spectacular views of the mountains’ perfect cone at every turn – framed by rainforest trees.

The entire area is protected as a national park, a larger conservation area and a series of private reserves – all part of the 204,000-hectare Arenal Conservation Area.

Over the years, a series of luxurious hotels and a string of hot river spas grew around its flanks and ecotourism parks with canopy walkways – at toucan’s eye level – were built in the beautiful cloud forests around the mountain.

It’s illegal and potentially dangerous to summit the mountain itself, but there are great hikes in the area; trails run across lava fields through pine woods filled with peccary and parakeets. Other trails lead to waterfalls like the 75m-high La Fortuna, which drops into a refreshing, clear-water pool that you can hike to and swim in.

There’s a range of other bucket list things to do in and around the national park too.

Canopy walkways offer monkey-eye views and the park environs have some of the country’s longest and fastest zip lines. There’s also rainforest river kayaking, tubing and white-water rafting, mountain biking and canyoning.

Adult price: £11

Good for age: 4+

La Fortuna Waterfall

  • Arenal National Park, Alajuela Province, Costa Rica

La Fortuna Waterfall


Lost at the end of a steep trail in misty forest on the fringes of Arenal National Park, this beautiful 75m-high waterfall drops into a refreshing, clear-water pool surrounded by moss-covered boulders.

It’s a 10-minute walk down a 500-step wooden staircase to get there (and 15-minutes back up) from the car park, but it’s an idyllic spot, worth the walk, and a wonderful place to swim. Go early though – it gets crowded, fast.

Getting there & doing it

Arenal Volcano National Park (the part of the volcano you can access) is 18km from downtown La Fortuna and you can get there by hire car or taxi for the cab fare (about US$30 one way) plus the park entry cost of US$15. Cabs will also drop you at trails and pick you up at the other end.

Some of the attractions (like the canopy walkways and the La Fortuna waterfall hikes) can be done solo. You’ll need a local guide, however, to hike in Volcan Arenal National Park whose entrance lies some 12km west of Fortuna Town. These are easily organised through hotels and guest houses or local agencies in La Fortuna village itself.

Organised tours make life easy by providing all logistics and knowing what’s best to do where and when. They’ll often also offer combos that combine several bucket list activities into one action-packed day.

Or you can base yourself in the park at Arenal Observatory Lodge – the only hotel in the park, with wonderful up-close volcano cone views and forest trails running from the lodge itself.

When to do it

The Arenal volcano region has its own regional climate. The driest period – when the volcano’s perfect cone is most easily seen – is January-late April. Rain is heaviest in June, October and November. However, the area can cloud over at any time of the year.

Average temperatures are warm and humid all year round – varying by only a few degrees, as you’d expect in the tropics and peaking at around 25 °C in April and May.
