One of my favorite parts of Costa Rica was a horseback tour from Fortuna to Monteverde. We took a boat across the Lake Arenal, which is absolutely gorgeous. We then dropped off our bags and met up with a our horseback tour. We then traveled for three hours on horseback to Monteverde, and it was absolutely amazing because you really get the chance to see all the scenery. To top it off, the tour ends at a restuarant at the top of hill overlooking the lake and the volcano. It's definitely the best part of the trip.
