Best time to visit Llanos de Cortes waterfall
Considering the best season to visit Llanos de Cortez waterfall you have to take the rainy season into account. Generally, the rainy season in Guanacaste lasts from May to mid-November. This results in powerful waterfalls from August until at least December. So on the other hand, if you visit the Costa Rica waterfalls in general, you can expect them to be a little drier when visiting at the end of the dry season. This will be in the months March, April and May.
In terms of the best time of the day to visit, it totally depends what you come for. If it’s just to relax and swim, any time is good. But if you want to have a peaceful experience, then try to get there as early as possible to eventually have the waterfall for yourself.
