Coron town is small and unpolished, a single main strip of grilled-fish stalls and dive shops under a hillside sign spelling out its name, and that's easy to mistake for the whole story. The real draw is the bay around it: a dozen WWII Japanese Navy wrecks sitting where they sank in 1944, and a short climb over a limestone ridge to a lake so clear it's used as the benchmark for water clarity in the entire country.

## Coron

A small town on a bay ringed by limestone karst, holding a dozen sunken WWII wrecks and a short climb to one of the clearest lakes in the Philippines.

On September 24, 1944, US Task Force 38 sank ten Japanese Imperial Navy ships anchored in Coron Bay in a single air raid; a dozen wrecks have since been located, sitting between 10 and 43 meters down and now encrusted in coral and thick with fish. The shallower ones, like the Olympia Maru, are diveable by anyone with an open-water certification, and the Skeleton Wreck — reduced to little more than its ribs and keel — is shallow enough to snorkel.

Kayangan Lake is the other reason people fly to this specific island rather than anywhere else in Palawan: a short, steep climb over a limestone ridge opens onto a lake mixing fresh and salt water, ringed by cliffs, consistently rated among the cleanest water in the country. The Twin Lagoon nearby does something similar at sea level — swim or duck through a gap in the limestone wall between two lagoons, and the point where the cool fresh water meets the warm salt water visibly shimmers at the surface.

The town itself is a single main strip under a hillside arch spelling out CORON in block letters, lined with grilled-fish carinderias and dive shops rather than resorts — most travelers base themselves here specifically to be five minutes from a boat, not to linger in town.

Highlights:

- The WWII Japanese shipwrecks — a dozen ships sunk in a single 1944 air raid, now diveable and snorkelable coral-encrusted wrecks in Coron Bay.
- Kayangan Lake — a limestone-ringed lake reached by a short ridge climb, rated among the cleanest water in the Philippines.
- Twin Lagoon — two connected lagoons split by a limestone wall, with a visible thermocline where fresh and salt water meet.
- Siete Pecados — a cluster of small reef islets with some of the healthiest snorkeling coral around Coron.

- **Best time to go:** November through May, outside typhoon season, for calm water and reliable boat access to the outer bay's wrecks and lagoons.
- **Tip:** Book an island-hopping boat tour rather than trying to reach Kayangan Lake or the wrecks independently — nearly all of Coron's real attractions are spread across the bay and only reachable by boat.
- **What to eat:** Look for grilled fish and pork cooked over open charcoal along the main strip's carinderias, served on banana leaf with rice and a side of vinegar-chili dip — Coron's actual everyday food, not a resort menu.
- **Where to stay:** Base yourself in Coron town itself, close to the pier — nearly everything worth doing is a boat ride from there, and the town center keeps food and dive shops within walking distance.
