Concha de Perla: the free swim that surprises people
Concha de Perla near Puerto Villamil, Isabela: the free-access tidal pool with sea lions and turtles, what to expect, and when the water is at its best.
Concha de Perla is a shallow, mangrove-fringed tidal pool a short walk along the main road from the Puerto Villamil pier on Isabela, and it is the best argument for not over-scheduling this island. No ticket, no boat, no guide: walk the wooden boardwalk from the pier area, put your mask on, and share calm water with sea lions, turtles and schools of reef fish. It is one of the very few genuinely good snorkel sites in Galápagos you can simply show up at: free access, no booking, no fixed hours. A rope line marks the swimming boundary; stay inside it.
What it is
Picture a natural swimming pool behind the beach line: mangroves around the edge, a sandy-and-rocky bottom, water that connects to the bay through a narrow entrance. The mangroves filter the water and shelter the young stuff; the bay entrance brings in the visitors. Depth stays modest, which is why it works for all ages, and the platform/rocks at the edge make getting in and out easy.
What you will see
- Galápagos sea lions: the resident group treats swimmers as part of the furniture, and the young ones will check you out at speed.
- Green sea turtles, feeding on the seagrass, tolerant and close.
- Schools of reef fish, small rays resting on the bottom, and the odd penguin passing through in the cool season.
- Iguanas drying on the mangrove roots at the edge, in classic Isabela fashion.
Visibility swings with tide and swell; on a calm, clear day it competes with some paid tours, and on a stirred-up day it is a pleasant swim rather than a spectacle. Calm mornings are the reliable window; the sea state by month explains the pattern (the water is generally at its calmest and clearest in the warm season, December-May).
How to do it right
- Go at high tide or on a calm morning: the pool is shallow and the entrance silts up when the sea is rough.
- Bring your own mask and fins or rent in Villamil town; water shoes help over the rocky patches.
- Reef-safe sunscreen only, applied well before you get in; better yet, a rash guard and no sunscreen in the water. The park restricts sunscreens with oxybenzone and octinoxate, which harm marine life.
- Two metres from the animals, no touching, no feeding, the park rules apply here exactly as on any visitor site.
- Do not leave valuables on the beach; there is no lockbox and no attendant.
Where it fits
Concha de Perla is the free complement to the paid water day on Isabela: after Los Túneles or a Sierra Negra morning, it costs nothing to float for an hour before dinner, and sunset on the beach next door is the island’s daily ritual. It is also the answer to “what do we do on the afternoon we arrive”, since the ferry gets in mid-afternoon and everything else worth doing needs a morning. Our Puerto Villamil guide sequences the whole island.
Free sites like this are why land-based Galápagos can be done well on a budget; the budget guide does the arithmetic. Galapagos Dana Tours books the tours that do need a boat, and Las Terrazas de Dana Boutique Lodge & Spa, our lodge in Mindo Cloud Forest, is the decompression stop we recommend when the islands are done (combining Galápagos and Mindo).
Tides, timing and the walk in
The pool works on the tide. At high tide the water is deepest and clearest and the entrance through the mangroves fills, which brings the turtles and the sea lions in with it; at low tide the pool shrinks to a shallow basin and the rocks at the edge are exposed and slippery. Check the tide table at your hotel or ask at the pier, and aim for the two hours either side of high water. Mornings beat afternoons in every season, because the wind rises after midday and stirs the sand.
Getting there is part of the charm: from the pier, the raised wooden boardwalk runs about 200 metres through the mangroves, and sea lions and marine iguanas nap on the planks, which means you step around them rather than over them. The boardwalk ends at a small deck with a ladder into the water; there are no lockers, no shade and no lifeguard, so bring only what you can leave in a dry bag on the deck. The pool is inside the national park, and the normal rules apply even though there is no ticket: no touching, no feeding, two metres from every animal.
