The valley below Arenal Volcano is cattle country as much as rainforest, and the mix of open pasture, river crossings, and secondary forest makes for varied riding that the hiking trails don't reach. Several outfitters in the La Fortuna corridor run half-day rides through the valley with the volcano as the backdrop — the view of Arenal from horseback in open pasture on a clear morning is the version of this landscape that stays with people. Longer rides push into the forest margins where the canopy closes overhead.
Dry season is the most comfortable window: dry trails, firm pasture, and morning air cool enough for a long ride without the humidity that makes green season demanding. The January through April window is when clear volcano views and good conditions are most reliable together. Green season riding is available and the forest is more vivid after rain, but mud limits the routes operators can safely run. Most outfitters include transport from La Fortuna and accommodate riders with no prior experience.

Whether you visit in dry season or green season, the Arenal basin follows a consistent pattern: mornings are clear, afternoons bring cloud and rain. Every activity — the Mistico Hanging Bridges, the volcano hike, horseback riding, the La Fortuna Waterfall — is better before noon. Guides who have worked here for years build all their tours around early starts. Follow their lead.
There are dozens of hot spring operations around La Fortuna, from large commercial parks with multiple pools and swim-up bars to smaller, quieter pools fed by the same geothermal source. The best experiences are at properties with their own private springs. The commercial parks are crowded in peak season and serve a different purpose entirely. Know which you want before you book.
The Caño Negro Wildlife Refuge is 1.5 to 2 hours north of La Fortuna near the Nicaraguan border. A day tour by motorboat on the Río Frío delivers jabiru storks, caiman, freshwater turtles, migratory waterfowl, and a density of birdlife that makes Mistico look like a warm-up. Most operators include lunch and run from roughly 7am to 4pm. Book it for a day when you want something different from the volcano.
