How similar is Rincón de La Vieja National Park to Yellowstone National Park? We've been to Yellowstone (and also Rotorua in New Zealand), so are not interested in going to Rincón if it's mostly similar to those. We will be in Costa Rica in mid-November and have six days not yet accounted for. (The other four will be in San Jose and for visiting the Doka Coffee Estate and La Paz Waterfall Gardens.) I'm trying to decide whether to spend all six of those days in the Arenal and Monteverde areas or to add somewhere else, such as Rincón de La Vieja. We fly home from Liberia.
