El Nido's Lagoons: The Crown Jewels Explained
TL;DR
El Nido's four main lagoons are the reason millions visit Palawan. Big Lagoon (Tour A) is the iconic kayaking paradise; Small Lagoon (Tour A) is an intimate enclosed pool you access by swimming through a cave; Secret Lagoon (Tour A) is a hidden beach behind a rock opening; Cadlao Lagoon (Tour D) is the uncrowded alternative. All are formed by limestone karst geology — the same process that created Halong Bay. Best times: Big Lagoon before 10:30am (light), Small Lagoon late morning (calmer water). Bring aqua shoes (mandatory), underwater camera, reef-safe sunscreen. Environmental fee ₱400.

Before understanding the lagoons, understand the geography. El Nido sits on the Bacuit Archipelago, a collection of limestone islands formed millions of years ago when the area was underwater. As sea levels dropped, these limestone towers were exposed. Water (rainwater, seawater) dissolved the limestone over millennia, carving caves, tunnels, and enclosed pools.
The result: limestone karst — the same dramatic geography that defines Halong Bay (Vietnam), Krabi (Thailand), and Palau. When you look at El Nido's towering cliffs riddled with caves, you're looking at karst in action.
The lagoons are the jewels of this system. Some are partially enclosed (Big Lagoon), others fully enclosed (Small Lagoon), others hidden behind rock openings (Secret Lagoon). Each is formed by a natural pool within this karst landscape.
Big Lagoon (Miniloc Island) — The Iconic One
What It Is
A massive enclosed lagoon on Miniloc Island, roughly 300 meters across, ringed by 300–400 meter limestone cliffs. You access it by boat, entering through a narrow opening (like passing through a natural gateway). Once inside, you're in a lagoon — the water is impossibly clear and shallow (2–5 meters in most areas), turquoise, and protected from ocean swells. It feels otherworldly.
Why It's Special
Kayaking: Most boats include two complimentary kayaks. You paddle across the glassy lagoon, looking up at 300m limestone walls. No motorboats inside; just paddles and silence. It's one of Southeast Asia's best kayaking experiences. The rock formations are dramatic; many have names: the Cathedral (a tall spire), the Twins (two peaks), the Eye (a cave opening that looks like an eye).
Photography: Big Lagoon is the most photographed spot in El Nido. The limestone walls reflect in the water, creating mirror-like compositions. Early morning light (7–9am) is golden; midday (11am–2pm) is harsh and washed out. Arrive early or book sunrise/early tours.
Snorkeling: Snorkeling in Big Lagoon is good but not exceptional. The lagoon is shallow and surrounded by limestone walls, not a reef system. Fish are fewer than open-water snorkel sites. But the setting is breathtaking — you're snorkeling inside a cathedral of rock.
Best Time of Day
8:30–10:30am. Arrive when boats first enter; the light is diffuse and golden, water is calm, and you have the lagoon mostly to yourself before crowds arrive (by noon, 10–15 boats are inside). If you're booking, request the earliest departure time (8:30am sharp, not 9:00am).
Tips
- Kayak rentals: Most operators include 2 kayaks per boat. If your group is larger or you want more kayaks, ₱150–200 per rental. The kayaks are basic but adequate.
- Aqua shoes: Mandatory. The entry to the lagoon involves wading or swimming through shallow water; the seabed has sharp coral and rock. Water shoes protect your feet.
- Camera: Bring an underwater camera or GoPro. Big Lagoon is the backdrop for most El Nido photos.
- Timing: Don't visit if you're doing this for the "Instagrammable" factor alone. Yes, it's iconic, but if you rush through to get photos, you miss the experience of paddling in silence inside a limestone cathedral.
Small Lagoon (Miniloc Island) — The Intimate One
What It Is
A second lagoon on Miniloc Island, smaller and more enclosed than Big Lagoon (roughly 100 meters across). Unlike Big Lagoon, which you enter by boat through a wide opening, Small Lagoon requires you to swim. You approach by boat, then everyone puts on snorkels and swims through a narrow cave opening (about 2 meters high, 5 meters wide, sometimes partially submerged) into the enclosed lagoon. Once inside, you're in a secret pool surrounded by limestone walls, with no boat — just swimmers.
Why It's Special
The experience: Swimming through the cave opening is thrilling. The water is so clear you can see 10 meters ahead. As you emerge inside the lagoon, the cave ceiling opens up and you're in an enclosed pool. It feels like discovering a secret room. The lagoon is pristine, shallow (2–4 meters), and the only sound is the water lapping against limestone.
Solitude: Because accessing Small Lagoon requires swimming and the space is small, fewer tourists visit compared to Big Lagoon. It's intimate.
Photography: Underwater photos are better here than Big Lagoon. The cave opening creates dramatic silhouettes, and the enclosed space means better light composition. Bring an underwater camera.
Best Time of Day
Late morning (10:30am–12:00pm). Morning tides are lower, making the cave opening lower and less water pressure. By late morning, tide is higher and water flow is calmer. Wait until your guide says water conditions are optimal.
What to Bring
- Aqua shoes: Mandatory. The cave passage has sharp rock walls and the lagoon floor is rough limestone. Your feet will thank you.
- Snorkel gear: You'll be snorkeling through the cave and inside the lagoon. Your own mask/snorkel is better than rentals (fits properly, better visibility).
- Underwater camera: The cave opening and interior are photogenic.
- Confidence: You need to be comfortable swimming through a cave passage. It's safe (your guide monitors, the passage is only 5–10 meters), but if you're claustrophobic or anxious, tell your guide. They'll give you the option to skip or modify.
Depth & Safety
The cave passage is shallow (1–2 meters), and once inside the lagoon, depth ranges from 2–4 meters. No deep diving; it's safe for swimmers of all levels. Current is minimal; water is calm.
Secret Lagoon (Miniloc Island) — The Hidden Beach
What It Is
A third pool on Miniloc Island (same island as Big and Small Lagoons), hidden behind a low rock opening. Unlike Small Lagoon (which you swim into), Secret Lagoon has a beach. You access it by wading through a narrow rock gap (at high tide, the water comes up to your chest or shoulders; at low tide, it's waist-deep) into a secluded beach cove.
Why It's Special
The wade: Pushing through the rock gap is an adventure. Your guide leads; the passage is stable, not dangerous, but it feels daring — you're squeezing through a narrow opening between limestone walls into a hidden beach beyond.
The beach: Once through, you're on a white sand beach that feels private and untouched. Few tourists reach here; most are content with Big and Small Lagoons. The beach is small (maybe 20 meters), surrounded by 50-meter cliffs, and calm water.
Snorkeling: Snorkeling off Secret Lagoon beach is basic (shallow, not much coral), but the setting is extraordinary — you're snorkeling in a hidden cove.
Best Time of Day
Mid-day to afternoon (12:00pm–3:00pm). High tide makes the rock passage easier to navigate (more water depth means you don't scrape). Low tide narrows the passage and makes it tighter.
Tips
- Aqua shoes: Mandatory. The rock gap has sharp limestone; your feet will slip without grip.
- Tide timing: Ask your guide about tide times. High tide = easier passage, lower tide = narrower passage. Neither is dangerous; it's a matter of comfort.
- Confidence: Similar to Small Lagoon, this requires comfort wading through a narrow opening. It's safe, but tell your guide if you're nervous.
- Change of plans: If tide is very low, the passage may be less appealing. Trust your guide's judgment on whether to visit.
Cadlao Lagoon (Tour D) — The Uncrowded Alternative
What It Is
Cadlao Island's lagoon — more open than Big Lagoon (not as enclosed), but equally beautiful and dramatically quieter. You'll see perhaps 1–2 other boats instead of 10–15 at Big Lagoon. The limestone walls are impressive, and kayaking is available, but the lagoon is less defined and more open to the ocean.
Why It's Special
Solitude: Cadlao Lagoon gets a fraction of Big Lagoon's traffic. If you value peace over "iconic," this is your lagoon.
Kayaking: Kayaking in Cadlao is similar to Big Lagoon — paddle among limestone walls, explore quiet coves, zero motorboats. The experience is less enclosed, more open, but equally serene.
Photography: Less touristy doesn't mean less beautiful. Cadlao has dramatic light and fewer crowds in photos, which some photographers prefer (more authentic, fewer people in backgrounds).
Best Time of Day
Early morning or late afternoon (7:30–9:00am or 2:30–4:00pm). Any time is quiet at Cadlao, but early morning light and late afternoon golden hour are magical.
Access
Cadlao Lagoon is only on Tour D. If you want to visit, you must book Tour D specifically.

Aqua Shoes (Mandatory)
All lagoons require aqua shoes. The seabeds are sharp limestone and coral. Flip-flops and canvas shoes don't protect. Get water shoes with grip soles (₱250–500 at El Nido shops). Once you have them, keep them with you for all water activities.
Underwater Camera
Lagoons are photogenic. A GoPro, waterproof action camera, or even a smartphone in a waterproof case (₱200) will capture memories. Underwater camera footage of swimming through Small Lagoon's cave opening or paddling in Big Lagoon is professional-quality.
Reef-Safe Sunscreen
Palawan bans oxybenzone and octinoxate (chemicals that bleach coral). Use reef-safe SPF 30+ lotion. Bring from home (it's expensive in El Nido) or buy locally. Reapply every 2 hours.
Dry Bag
Keep valuables, extra clothes, and snacks in a dry bag. A lightweight roll-top bag costs ₱300–600 locally. Protects your camera, phone, passport copies, and money.
Snorkel Gear (Your Own vs. Rental)
Rental: Tours include rental gear (mask, snorkel, fins). It works but fits poorly for many people.
Your own: If you own snorkel gear, bring it. Personal mask fit means better visibility and comfort. A basic snorkel set costs ₱500–1,000 in El Nido.
Geology & Photography Tips
Understanding the Light
Limestone reflects light. In Big Lagoon, direct sun creates harsh shadows and glare by noon. Early morning (8:30–9:30am) offers diffuse, golden light — ideal for photography. Late afternoon (3:00–4:30pm) is golden hour, good for sunset colors but water is rougher. Midday (11am–2pm) is harsh but gives the water brilliant turquoise color. Choose your lagoon visit based on lighting goals.
Kayaking as Photography
Kayaking in Big or Cadlao Lagoon is better than snorkeling for unique angles. From a kayak, you're at water level looking up at 300-meter cliffs; you capture scale and drama that water-level snorkelers miss. Bring a GoPro mounted on your kayak.
Cave Entrance Photos
Small Lagoon's cave opening and Secret Lagoon's rock gap are photogenic framed shots. Silhouettes of swimmers emerging into light are stunning. Bring an underwater camera and experiment with backlighting (sun behind the cave opening).
Golden Hour Magic
Limestone glows at sunrise and sunset. If you can swing an early morning boat or late afternoon tour, the light will be exceptional. Cadlao Lagoon at dawn is magical — you'll have it mostly to yourself and light is golden.

Frequently Asked
Can I visit lagoons without taking a tour?
No. The lagoons are protected marine reserves. You can only access them via authorized tour boats. This protection keeps them pristine.
Is it safe to swim through Small Lagoon's cave?
Yes. The cave passage is short (5–10m), shallow (1–2m), and well-traveled by thousands annually. Your guide monitors safety. If you're uncomfortable, tell your guide — they'll support you or offer to skip it.
What happens if I lose my aqua shoes in the lagoon?
Bring a secure strap or clip. If shoes fall off in water, they're typically recoverable (water is clear, you can see them). Wear shoes with straps, not loose water sandals.
Are the lagoons cold?
No. Water temperature is 26–28°C (79–82°F) year-round. Tropical and comfortable. You might want a rash guard (UV shirt) to prevent sun burn, not for warmth.
Do I need to be a strong swimmer?
No. Lagoons are shallow and calm. All have life jackets available. You don't need to be a strong swimmer; confidence in water and comfort with snorkeling is enough.
Can I kayak in all the lagoons?
Kayaking is emphasized in Tour A (Big Lagoon) and Tour D (Cadlao). Small Lagoon's kayaking is possible but less focused (most visit by swimming). Secret Lagoon doesn't offer kayaking (it's accessed by wading).
