Best time to visit La Fortuna Costa Rica
The best time to visit La Fortuna is in the dry season that runs from December through April. However, if you visit in the shoulder season that runs from April through August, you will have a chance of fewer crowds and lower prices. However it can rain more often during these months. This also has its benefits because rainy season, also known as green season in Costa Rica, results in beautiful lush rainforest.
Keep in mind that Arenal volcano usually shows itself more often in the dry season when there are fewer clouds and rainy days.
