Los Arcos (The
Arches) is one of the most popular diving and snorkeling spots
in Bahía de Banderas (Bay of Flags) and is
visited by many of the local tourist companies (link) and dive
shops (link). It comprises five granite islets from 5-50 m (16-160 ft) high about 10 km (6 mi) south of Puerto Vallarta. I snorkeled the rocks when we were here in early April and again when we
returned in early June.
