We've used the shuttle tours to go from Quepos to Malpais, which is an extension of the Jaco-Montezuma shuttle boat option. They picked us up in time and without trouble at our hotel on the Playita (which includes a very bumpy steep hill to climb) and got us in time to the bost on the beach north of Jaco. Te boat ride to Montezuma was nice and we saw dolphins and turtles. The captain even stopped a few minutes so we could catch a glimpse. Once in Montezuma, we were quickly ushered to our taxi and en route to Malpais. Nothing bad to say, it's the perfect travel option and the price was ok.
