Twin Lagoon | Coron

Twin Lagoon is a major destination in Coron, Palawan, consisting of two lagoons separated by a narrow limestone wall. It is a centerpiece of "Tour B" and "Super Ultimate" boat tours.

Visual Characteristics

The lagoons are surrounded by towering, jagged limestone karst formations. The water is a mix of fresh and salt water (brackish), leading to a thermocline effect where layers of warm and cold water meet, often causing a "blurry" visual effect underwater. The first lagoon is where boats dock, while the second, larger lagoon is hidden behind a cliff.

Location & Access Logistics

Address: Coron Island, Coron, Palawan, Philippines.

Access: Only reachable by boat from Coron town proper.

Transport: * Boat: Motorized bangka (outrigger boat).

Entering the Second Lagoon: Visitors enter the hidden lagoon by either swimming through a narrow underwater crevice during low tide or climbing over a wooden ladder/staircase during high tide.

Entry: Requires an entrance fee (approx. 200 PHP), usually included in tour packages.

Historical & Ecological Origin

The area is part of the ancestral domain of the Tagbanua tribe. The lagoons are technically sinkholes formed by the collapse of underwater caves. The mixing of cool freshwater from underground springs and warm saltwater from the sea creates a unique ecosystem.

Key Highlights & Activities

Swimming: The calm, buoyant waters are ideal for swimming.

Kayaking: Many tours offer kayaks to navigate the interior of the second lagoon.

Thermic Layers: Experiencing the sudden temperature changes while swimming.

Photography: The dramatic cliffs and the wooden ladder at the entrance are popular subjects.

Infrastructure & Amenities

There is no permanent infrastructure within the lagoons. A small wooden platform and ladder are maintained at the entrance for access. Life vests are provided by tour boats. Cellular signal is non-existent.
