Orchids, bromeliads, agaves and wild palms line the paths of this gorgeous nature park, located 30km south of Puerto Vallarta. Follow hummingbirds through fern grottoes, or head down to bask in a chair on the sand and swim amid huge boulders in the river below. Take the ‘El Tuito’ bus (M$24) from the corner of Carranza and Aguacate in Puerto Vallarta, or hop in a taxi (about M$300).
