The distinctive underwater sights worth planning around. Descriptions are curated planning info — always verify local access, rules and conditions before you set out.
01
Museo Atlántico
Underwater museum📍 Off Playa Blanca, Lanzarote
Jason deCaires Taylor's Atlantic installation — a field of submerged human figures and a sunken wall, built to draw diving pressure away from natural reef. One thing has to be said plainly: the installations sit at recreational diving depth, so this is a dive site and not a snorkel site. It belongs in this catalog because it is the islands' signature underwater site and the one snorkelers ask about, and because the honest answer is that you visit it on a dive, not on a snorkel.
Dive-depth installations, visited by guided divers — do not plan a snorkel trip for the museum itself. The snorkeling on Lanzarote is the shallow coves and reef.
02
Playa Chica, Puerto del Carmen
Shore reef📍 Puerto del Carmen, Lanzarote
A small sheltered cove in the middle of Lanzarote's main resort, with an easy entry over sand and rock and fish in shallow water — the island's established shore-dive and snorkel bay, and the simplest way to get in the water on Lanzarote without a boat.
A working dive bay in season, with boat and diver traffic and a busy beach — keep clear of the diver entry lines and swim with a marker float.
03
El Puertito, Tenerife
Shore reef📍 El Puertito de Adeje, south-west Tenerife, below the Los Gigantes cliffs
A tiny cove on Tenerife's sheltered south-west coast where resident green turtles are a regular sight in shallow water over rock and sand — the island's best-known shore snorkel, and calm enough on most days for an unhurried swim from the beach. The Los Gigantes cliffs, which drop straight into deep water, are just up the coast.
The turtles are wild and protected and this is a small, popular bay — never touch or chase them, follow local guidance on how close to approach, and expect other swimmers in the water.
04
La Restinga marine reserve, El Hierro
Marine reserve📍 La Restinga, El Hierro (Reserva Marina del Mar de Las Calmas)
El Hierro's marine reserve protects a stretch of calm, sheltered water off the island's southern tip, over volcanic rock, boulders and shallow reef — a reserve genuinely reachable from shore in the Mar de las Calmas, and the quietest of the islands' established snorkel spots.
A protected reserve with its own rules and restrictions on diving and fishing — verify the current reserve rules with a local operator before you swim.
05
Las Canteras, Gran Canaria
Shore reef📍 Las Palmas de Gran Canaria, north-east Gran Canaria
A long city beach sheltered by a nearshore rock bar that keeps the bay unusually calm, with shallow rock, sand and fish along its inner edge — a genuinely easy urban snorkel and the sensible choice when the trade wind is up on the other coasts.
An urban beach used by swimmers, learners and water-sports traffic — stay on the sheltered side of the bar, stay inside the swimming areas, and check the local flag warnings and lifeguard advice.
