The areas between these two provinces generally rain at any time of the year. But the heaviest downpour is between June and November. Oddly, their dry or summer month is October!

You can have the entire park, beaches, and other landscapes all by yourself.

3. Big earnings on travel costs – Since most travelers opt for a dry season, the peak travel dates are between December and April. The low season in Costa Rica is from May to November.

Try visiting Rio Celeste Waterfalls and La Paz Waterfall Gardens.

5. Tranquil hot springs – Costa Rica is home to countless beaches, but few are aware that it is also home to numerous hot springs. During the rainy season, not many people travel to the country. So, you might be having the whole hot spring by yourself, immersing into a magical and relaxing soak in the warm water with a cool falling mist.
