Through the Limestone Gate: Twin Lagoon and Coron's Quiet Magic
A swim-through limestone cathedral where early mornings make all the difference
The boat pushes close to a band of gray limestone that rises like a cathedral wall from turquoise water. A guide points up—there, a metal ladder is bolted into the rock, the only visible passage for humans between two glassy chambers: the outer lagoon, shallow and sunlit, and the inner, cooler basin ringed by sheer cliffs. Around you the sea smells of salt and coral; the cliffs, sun-warmed, drip with tiny green plants. When you duck beneath the low, reef-strewn tunnel at high tide, the water seems to hold its breath and pull you into a world where silence has weight and the reef hums like a sleeping engine.
Trail Wisdom
Arrive at first light
Boats that reach the lagoons before 8:30 a.m. avoid most of the crowds and get the best light for photos.
Bring aqua shoes
The approach involves jagged rock and coral; soft-soled water shoes protect feet and make ladder climbs safer.
Use reef-safe sunscreen
Oxybenzone-free sunscreen reduces harm to corals; apply on land to minimize wash-off.
Carry a dry bag and ID
A small waterproof bag keeps phone, cash, and permits safe during boat transfers and swims.

- •Siete Pecados Marine Park—community-managed snorkeling with vibrant reefs

Conservation Note
Support operators who contribute to local conservation fees, avoid standing on reefs, and use reef-safe products to protect fragile coral ecosystems.
Coron’s waters hold WWII Japanese wrecks and the Tagbanua people have inhabited the islands for centuries; community stewardship now shapes many marine protection policies.
Seasonal Guide
spring
Best for: calmer seas, sunrise photography, full-day island loops
Challenges: higher temperatures, more visitors
Spring (March–May) is the dry season—warm, calm water and clear skies make it the most popular time to visit.
summer
Best for: long daylight hours, extended snorkeling, private boat charters
Challenges: occasional afternoon squalls, peak tourist crowds
Summer months keep seas warm and inviting, but afternoons can bring short, heavy showers—plan morning activities.
fall
Best for: fewer crowds, lower prices, good snorkeling visibility
Challenges: intermittent rain, choppier boat rides
Fall (October–November) sees fewer tourists; visibility remains good but weather can be less predictable.
winter
Best for: dramatic skies, quieter piers, budget travel
Challenges: rainy season onset in some months, reduced boat schedules
Winter overlaps with the wetter months—expect variable conditions and occasional cancellations; plan margin time.

Common Questions
How long does it take to reach Twin Lagoon from Coron town?
Most boats take about 30–45 minutes from Coron town to the Twin Lagoon area depending on sea conditions and the exact route.
Can beginners swim through the tunnel?
Yes—if you are a basic swimmer. At high tide the channel can be narrow and requires sustained swimming; life vests are commonly provided.
Is there an entrance fee or permit?
Yes—local entrance fees and environmental levies are commonly charged; many tours include these in the price but confirm in advance.
What’s the best time of day to visit Twin Lagoon?
Early morning (before 9 a.m.) for fewer crowds, softer light, and calmer seas; afternoon tends to be busier.
Can I combine Twin Lagoon with other sites in one day?
Absolutely—Twin Lagoon is routinely combined with Kayangan Lake, Barracuda Lake, Coral Gardens, and a wreck snorkel on full-day island-hopping tours.
Are guides and life jackets provided?
Most organized tours supply a licensed guide, life jackets, and basic snorkeling gear for rent; private tours may include additional equipment or services.
What to Pack
aqua shoes, reef-safe sunscreen, snorkel mask, dry bag — for safety, reef protection, independent snorkeling, and keeping valuables dry
Did You Know
Twin Lagoon’s two basins are separated by a limestone wall formed from uplifted coral reef; at low tide visitors can climb over a ladder, but at high tide the only option is to swim through a narrow channel.
