Las Hornillas Volcanic Activity Center is located on the undulating slopes of Miravalles volcano. Here you can observe hot water springs, bubbling mud holes, fumaroles, and steam boilers that attract national tourists as well as foreigners. This is the only place in Costa Rica where you can take a walk inside the crater, watch and feel steam coming out of the boiling mud. Experience the therapeutic properties of the famous mineral clay and the hot springs water while you enjoy a wonderful landscape of this typical region of Costa Rica.  Our tour also includes a visit to the Miravalles rainforest.  The horseback ride and the tractor tour leave from the Volcanic Activity Center and start moving into the Volcano Miravalles protected area. Enjoy this full-day tour in the primary rainforest, with very safe hanging bridges, trails with waterfalls, and a visit to Catarata Escondida (Hidden Waterfall).
