Snorkeling at los Arcos
North, offshore beyond the Mismaloya cove, rise the green-brushed Los Arcos sea rocks, a federal underwater park and ecopreserve. The name comes from the arching grottoes that channel completely through the bases of some of the rocks.
Snorkeling near the wave-washed Los Arcos is a Puerto Vallarta “must do.” Swirling bunches of green algae and branching ruddy corals attract schools of grazing parrot, angel, butterfly, and goat fish.
Curious pencil-thin cornet fish may sniff you as they pass, while big croakers and sturgeon will slowly drift, scavenging along the coral- littered depths.
