The Best Free and Cheap Things to Do Around Arenal

A field guide to enjoying Arenal and La Fortuna on a budget, from free river swims and volcano views to affordable hikes and hot springs.

Arenal is famous for its adventure tours and luxury hot springs, but you don't need a big budget to have a memorable trip. Some of the best experiences here cost little or nothing at all. This guide covers the free and cheap things that let you soak in the real Costa Rica without draining your wallet.

I have spent years exploring this area on foot, by bike, and by bus. The tips below come from firsthand experience and local knowledge. They are honest, practical, and designed to help you enjoy Arenal on your own terms.

Free Volcano Views from the Public Viewpoints

You do not need to pay for a national park to see Arenal Volcano. The best free view is from the public lookout at the base of the volcano, on the road to El Castillo. Just drive or take a taxi to the small parking area near the old lava flows. On a clear morning, you will see the perfect cone rising above the green hills. Another great spot is the roadside pull-off on Route 142 near the Arenal Dam. Both are free and open to everyone.

Swimming in the Rio Fortuna

The Rio Fortuna is a clear, cool river that runs right through town. There are several free access points where locals swim. The most popular is just downstream from the La Fortuna Waterfall entrance. Park along the road and walk down a short trail to the riverbank. The water is refreshing after a hot day. Bring a towel and a snack. No entrance fee is required.

Hiking the Free Trails Around Lake Arenal

Lake Arenal has a network of public trails that are free to use. The best is the Sendero El Silencio, a flat loop through secondary forest near the lake shore. It takes about 40 minutes and offers good birdwatching. You can also walk the gravel road along the lake's edge for miles. The views of the volcano across the water are stunning, especially in the late afternoon light.

Cheap Hot Springs at the River

While the luxury hot spring resorts charge from $30 to $80 per person, you can find free thermal pools in the river near the base of the volcano. The most accessible spot is at the public access point on the road to El Castillo. Look for a small parking area and a short path to the river. The water is naturally heated by the volcano and mixes with the cool river. It is not as polished as the resorts, but it is free and authentic. Bring water shoes because the rocks can be sharp.

Low Cost Hikes: La Fortuna Waterfall and Mistico

Two of the most popular attractions are affordable if you go on your own. La Fortuna Waterfall charges an entrance fee of around $18 per person. You can walk down the 500 steps to the pool at the base. It is worth the fee for a swim in the cool, turquoise water. Mistico Hanging Bridges Park charges about $25 per person for a self guided walk on the suspension bridges. Both are cheaper than most guided tours and give you the freedom to go at your own pace.

Free Evening Activity: Frog Watching

After dark, grab a flashlight and walk slowly along any quiet road or trail near water. The area around La Fortuna is full of frogs, including the iconic red eyed tree frog. You do not need a guide. Just move slowly and listen for calls. This is a free way to see Costa Rican wildlife up close.

Your Next Step

Start your budget friendly trip by visiting the Rio Fortuna free swimming spot on your first afternoon. It is easy to find, free, and a perfect way to cool off after traveling. From there, you can plan the rest of your days around the free viewpoints and cheap hikes listed above.
