Bacuit Archipelago: Limestone Karst, Hidden Lagoons, and the Problem With Tour A

The Bacuit Archipelago spreads around El Nido in northern Palawan, Philippines - 45 islands and islets of limestone karst rising from green-turquoise water, with hidden lagoons behind them, coral reefs at the base, and enough visual drama to justify the considerable logistics of getting there. It is one of the more beautiful places in Southeast Asia and it is also, during Tour A on a peak December weekend, disappointingly crowded.

Tour A (Big Lagoon, Small Lagoon, Secret Lagoon, Shimizu Island) is the most popular route and visits the most dramatic sites. At Big Lagoon in high season you may share the water with 50 or more kayaks simultaneously. This is not a niche observation. Tour C (Helicopter Island, Secret Beach) and Tour D are significantly quieter on weekdays and worth choosing specifically for that reason. Private boat hire at PHP 5,000-8,000 per day lets you set your own pace and arrive at sites before the group tours. The price difference between private and shared (PHP 1,500-2,000 per person on shared tours) is worth it for anyone who values the experience over the logistics budget.

What You’re Actually Seeing

The limestone towers were formed when the sea level was lower and calcium carbonate accumulated over millions of years; subsequent sea-level rises left them standing in water with caves, arches, and enclosed lagoons that are now accessible by boat. Big Lagoon is enclosed on three sides by vertical limestone walls; the water inside is deep, clear, and the light changes dramatically from early morning to afternoon.

Secret Beach requires swimming through a cave passage to reach - not a long swim, but specific. The water inside is shallow and protected. This is the kind of site that is worth visiting exactly once and remembering for a long time.

The coral reef snorkelling at Shimizu Island and around the Twin Rocks is better than at many comparable sites elsewhere in Southeast Asia because the remoteness of the archipelago limited destructive fishing practices.

Getting There

The main routes from Manila: fly to Puerto Princesa (approximately 1.5 hours) and take a 5-6 hour van ride north to El Nido, or fly directly to El Nido’s small airport on Air Juan or other small carriers. The direct flight takes about 90 minutes from Manila but the schedule is limited and the aircraft small. Most visitors take the Puerto Princesa option.

From El Nido town, island-hopping tours depart from the beach near the main square. The town has grown substantially in recent years; accommodation ranges from guesthouses at PHP 500-1,000 per night to mid-range hotels. May through June, before the rains intensify, and September through October are the quieter and often better-weather alternatives to the December-April peak. Avoid the site entirely in July through August when typhoon risk and rough seas make boat travel unreliable.
