We took a riding tour with Alberto on a whim one afternoon, and we were very impressed with the experience. Neither of us had any meaningful horse riding experience, and this was not a problem because the horses were well trained. The tour offers pickup and drop off at your hotel.
Alberto's tour takes you to the the foot of the Volcano across a private property, where you can walk down to the base of the La Fortuna waterfall, and even swim in the river if you want. It's personalised, and depending on when you go, it could be a small group, or if you are lucky like we were, just ourselves. Alberto makes great conversation, and shares his experiences of growing up and working on the land in the area with an honesty that needs to be seen to be appreciated. It's a very personal tour, which is great when we compared it to some of the big box activities we had done. There are some steep mud banks and a brief river crossing, but the horses handle it fine - even if you don't!
A highly recommended way to see the area.
