Forest

Visits

2023-10-01: On the way to La Fortuna, it started to rain like crazy. I wanted to get to the hotel before dark. We arrived just after dark, and it was still raining cats and dogs.
2023-10-02: Walked around in the forest at our hotel in the morning. After breakfast, we paid a bunch of cash to walk to the Fortuna waterfall. The waterfall was fine, but we did not spend a lot of time there due to the short trail and screaming children. At night, we did the guided night walk where we saw lots of snakes and spiders.
2023-10-03: Walked around the hotel grounds a bit before heading out toward the Arenal National Park
