View Tour Details Green Season: May–November
The "rainy" or "green" season gets a bad reputation, but it's actually a fantastic time to visit. Mornings are often clear, with rain arriving in the afternoon. The landscape is incredibly lush, waterfalls are at their most impressive, and wildlife is more active. Prices drop significantly, and you'll have trails to yourself.
