Montaña Amarilla is a volcanic shore dive in a protected reserve near Las Galletas, known for yellow cliffs, lava formations, and underwater arches and caves. The route is shallow and scenic rather than dramatic, with sand patches, reef terraces, and rock walls that suit relaxed exploration. It is a good all-level dive when the sea is calm, and it can produce barracuda, octopus, moray eels, rays, and turtles.
