Beitrag in Río Segundo, Alajuela Province, Costa Rica

Hola muchahos,

I am visiting Costa Rica for the first time and I would like to impress my friend by showing the hidden gems of the country away from the tourist crowd. We will be spending our time driving around Arenal, Nicoya Peninsula, Jaco and Quepos. We will have atleast 2-3 days in all of these places. Do you guys know of any not so popular but beautiful places or fun activities to do in these region? We both love nature and like an adventure :) Thanks Ramesh
