The Green Season Advantage: Why Adventure in Arenal Gets Better with Rain

For many travelers, rain sounds like a reason to slow down. In Arenal, it’s often the opposite. The beginning of Costa Rica’s Green Season transforms the rainforest into something deeper, richer, and far more alive — especially for those looking for authentic adventure.

During May, the jungle surrounding La Fortuna becomes intensely vibrant. Trails feel fresher, the air is cooler, and the waterfalls flowing through the canyon gain new energy. This is why many experienced travelers actually prefer visiting during the green season in Costa Rica.

One of the best ways to experience this change is through canyoning with Pure Trek. Moving through a rainforest canyon and descending waterfalls using guided waterfall rappelling allows visitors to interact directly with the landscape rather than simply observing it.

The light rain typical of this season doesn’t interrupt the adventure — it enhances it. The jungle feels more immersive, sounds are amplified, and the environment becomes part of the experience itself.

Another advantage of traveling in May is the flexibility. With fewer peak-season crowds, guides can adapt the pace of the adventure and give guests more space to fully experience each descent and section of the canyon.

For travelers curious about the wild side of Costa Rica, the Green Season reveals something many visitors miss: adventure isn’t diminished by rain — it becomes more authentic.

In Arenal, May is when nature and adrenaline begin to move together again.
