So I am looking into going to the arenal observatory lodge for our honeymoon. My fiancée and I like to be active on our trips. We want to do many of the activities that arenal observatory lodge offers (white water rafting, Canopy Tour, Canoeing) but I am not sure how much they cost. I am trying to figure out how much money to save for this trip. Has anyone been here and know how much the activities cost or where I can find the information?
