La Fortuna is known as a gateway to Arenal Volcano National Park, comprised of two volcanoes. The active Arenal Volcano is still laced with lava flows. I did not have the opportunity to see the 70 meter La Fortuna Waterfall, so I did not include it below, but I highly recommend it if you are able to hike the trail.
What to do in La Fortuna
The Arenal Volcano is an active andesitic stratovolcano that measures at least 1,633 meters high. The Arenal Volcano National Park entrance is about a 25 minute taxi ride from the center of La Fortuna.
La Fortuna is home to some of the best river rafting I have ever experienced. Beside the actual river, I was able to see poison dart frogs and eat native mamon chino, guanabana, and pejibaye. Also, feel free to make fun of me in this picture.
The Arenal Volcano is visible throughout La Fortuna. I recommend walking around town, stopping at shops and restaurants, and talking to the locals and supporting their businesses.
