I am planning a trip to Costa Rica in March. I've been once before - to Arenal, Manuel Antonio, and Punta Islita - and we're hoping to see all new things this time. We will likely spend several days on the Osa Penninsula and a couple of days near Rincon de la Vieja enjoying the park and the hot springs. We'd also like to spend a few days on the beach - somewhere that isn't too crowded where we can take a kayaking tour, take a surf lesson (we've never been), swim, and enjoy good food. Any suggestions for a place on the Nicoya Penninsula (or elsewhere) that fits that description? Thank you!
