My husband and I are planning our first trip to Costa Rica. We will be going for 7 days and want to divide that time between Arenal (adventure) and a beach. We will be spending 4-5 days in Arenal and 2-3 days in Tamarindo (or another beach area that offers surfing - still need to domore research on it). I have searched the forum and a few sites and am confused about which month to go. We can go between May and December. We want to do some rafting, ziplining, hikes, hot springs, surfing, and maybe a few other activities; basically one - two activities per day and we want to be able to enjoy all those in appropriate weather. Based on our Arenal and beach holiday, which month do you think will be most enjoyable?
