12 best things to do in Arenal and La Fortuna

A warm, honest field guide to the top 12 activities in Arenal and La Fortuna, from hiking volcanoes to soaking in hot springs, with practical tips for first time visitors.

Welcome to Arenal and La Fortuna. This is a place where the volcano stands quiet most days, but the land around it is alive with rivers, waterfalls, and forest. After years of guiding friends and visitors through this area, I have put together a list of the 12 best things to do here. These are the experiences that feel true to the place, not just tourist traps.

Each activity is something you can do on your own or with a local guide. I have kept prices vague because they change, but I have noted where you might need to budget a little more. Let us get started.

Hiking Arenal Volcano National Park

The classic. The park has well marked trails through old lava flows and secondary forest. You will see how the forest has regrown since the 1968 eruption. The hike to the 1968 viewpoint is about 2 hours round trip. Go early in the morning for cooler weather and better wildlife spotting. Entry is around $15 per person, indicative.

Soaking in Hot Springs

Arenal is famous for its volcanic hot springs. You can find everything from free river spots near the bridge on the road to El Castillo to developed resorts with pools. The free spots are shallow and rocky, so bring water shoes. If you want a nicer experience, many hotels offer day passes from $30 per person, indicative. The water is warm, not scalding, and perfect after a hike.

Visiting La Fortuna Waterfall

This is a 70 meter tall waterfall inside a private reserve. You walk down about 500 steps to a swimming hole at the base. The water is cool and refreshing. The walk back up is steep, so take your time. Entry is around $18 per person, indicative. Go early to avoid crowds.

Exploring Mistico Arenal Hanging Bridges Park

A network of suspension bridges and trails through the canopy. You can see monkeys, toucans, and sometimes sloths from above. The walk is about 3 kilometers and takes 1.5 to 2 hours. It is not a high adventure, just a beautiful walk in the trees. Entry is around $30 per person, indicative.

White Water Rafting on the Pacuare or Sarapiqui Rivers

If you want a thrill, this is it. The Pacuare River is world class for rafting, with Class III and IV rapids through a jungle canyon. The Sarapiqui is a bit milder, good for families. Trips usually include transportation and lunch. Expect to pay from $80 per person, indicative for a full day trip.

Wildlife Spotting at Caño Negro Wildlife Refuge

A boat tour through flooded forest and wetlands. You will see caimans, monkeys, sloths, and many birds like herons and kingfishers. The best time is the dry season from December to April. Tours from La Fortuna take about half a day. Cost is around $60 per person, indicative.

Hiking to Rio Celeste in Tenorio Volcano National Park

A stunning turquoise river inside the park. The hike is about 4 kilometers round trip, with some muddy sections. The color comes from a chemical reaction between volcanic minerals. Go on a sunny day for the best color. Entry is around $12 per person, indicative.

Canyoning and Rappelling Down Waterfalls

For adrenaline seekers. You will rappel down several waterfalls in a canyon, with a guide handling the ropes. The tallest drop is usually around 40 meters. It is safe and fun. Expect to pay from $80 per person, indicative for a half day.

Horseback Riding to a Waterfall

A gentle ride through farmland and forest to a hidden waterfall. You do not need experience. The horses are calm and well trained. Many tours end with a swim. Cost is around $50 per person, indicative for a half day.

Night Walk in the Rainforest

A guided walk after dark to see frogs, snakes, and insects. The guides use flashlights to spot creatures. It is a completely different world from daytime. Many hotels offer this on their grounds. Cost is around $30 per person, indicative.

Visiting the Arenal Observatory Lodge

Even if you do not stay overnight, you can visit for the day. The lodge sits on a hill with a direct view of the volcano. There are trails and a small museum. The grounds are lovely. Entry is around $10 per person, indicative.

Relaxing at Lake Arenal

The lake is huge and windy. You can kayak, paddleboard, or just sit by the shore. The wind makes it popular for windsurfing and kitesurfing. The town of Nuevo Arenal on the north side is quieter than La Fortuna. No entry fee, just bring your own gear or rent locally.

That is the list. Twelve things that show you the real Arenal and La Fortuna. You do not need to do them all. Pick two or three that match your energy and curiosity.

Your Next Step

Start with one morning hike at Arenal Volcano National Park. Pack water, sunscreen, and a light rain jacket. After the hike, find a hot spring to soak your legs. That is the perfect first day in this place.
