Four Islands

This section is being updated and will be available shortly.

The Four Islands are Krabi's classic near-shore day-trip circuit: Koh Poda, Koh Kai (Chicken Island), Koh Tup and Phra Nang Cave Beach on the Railay peninsula. Linked by shallow turquoise water and, at low tide, a walkable sandbar, they showcase the province's karst-and-beach scenery in a single easy loop.

No other Krabi outing packs so much signature scenery into one affordable day: white beaches, the rooster-shaped rock of Chicken Island, snorkelling straight off the sand and the famous sandbar linking Koh Tup and Koh Mor. Departures from Ao Nang and Railay are short, making it ideal for first-timers.

Thale Waek, the emerging sandbar between Koh Tup, Koh Mor and Chicken Island, is the tour's showpiece at low tide. Koh Poda's postcard beach facing the karst stack offshore, the rooster-head rock formation, and the cliff-framed sands of Phra Nang complete a highlight reel of Krabi icons.

Snorkel the shallow reefs off Chicken Island, wade the sandbar when tides allow, swim and sunbathe at Koh Poda and visit Phra Nang's cave shrine. Longtail and speedboat tours run half or full days with lunch; private charters let you linger where crowds are thinnest.

Koh Poda's beach with its offshore karst pinnacle is the defining stop, and the low-tide walk across Thale Waek is not to be missed when conditions align. Chicken Island's rock formation, best seen from the water, and Phra Nang Cave Beach anchor the rest of the circuit.

Timing beats geography here: an early private longtail reaches Koh Poda before the fleets, and late-afternoon light empties the sandbar. The small reef off Koh Tup's quieter side often outsnorkels the busier Chicken Island shallows, and sunset returns past Railay's cliffs are quietly spectacular.

Phra Nang's cave shrine, where fisherfolk leave offerings to a sea princess spirit for safe voyages, adds a living cultural note to the beach day. The longtail crews themselves, mostly from local Muslim fishing families, carry Krabi's maritime tradition into the tourist era.

The islands sit within Hat Noppharat Thara–Mu Ko Phi Phi National Park, their shallows holding coral patches, reef fish and occasional turtles. Karst towers, tidal sandbars and hornbills on the larger islets make the circuit a compact lesson in Andaman coastal ecology.

Shallow, calm dry-season water, short boat legs and sandbar wading make this Krabi's most child-friendly island day. Life jackets are provided on tours, Koh Poda offers shade beneath its casuarinas, and half-day options suit younger attention spans.

The islands are day-use park territory with no nightlife; boats return by late afternoon. Evenings belong to Ao Nang's beachfront bars or Railay's laid-back cliffside scene, both minutes from the departure beaches.

Shoot Koh Poda's beach with the karst stack offshore, the rooster rock from a circling boat and the sandbar's ribbon of white between blue channels. Phra Nang's cliffs at golden hour and longtails anchored in gin-clear shallows complete the classic Krabi set.

These islets have long served local fishers as shelter and landmark, with Phra Nang's legend of a lost princess predating any tourism. As Ao Nang and Railay grew from the 1980s, the four-island loop became the province's defining tour, now managed under national park protection.

The circuit runs on southern Thai coastal culture: Muslim boat families, spirit beliefs at the Phra Nang shrine and an easy-going service tradition. Respecting the shrine, dressing modestly off the sand and treating crews courteously keep visitors in step.

November to April delivers calm seas, clear water and reliable sandbar walks at low tide, with December to February the peak. Monsoon months from roughly June to October bring swell, murkier water and occasional cancellations, though calm mornings still occur.

The Andaman pattern applies: dry season November to April, hottest March to May, southwest monsoon June to October with afternoon squalls. Tide timing matters year-round for Thale Waek, so operators plan departures around the tables.

No festivals occur on the islands themselves, though offerings accumulate at Phra Nang's shrine year-round. Songkran and Loy Krathong colour the mainland departure towns; check tide tables rather than calendars when planning this particular trip.

Depart Ao Nang or Railay in the morning, snorkel off Chicken Island first, walk Thale Waek at the day's low tide, then lunch and laze on Koh Poda. Finish at Phra Nang Cave Beach for a swim beneath the cliffs before the short ride home in late-afternoon light.

A full-day tour of six to seven hours covers all four stops with time to swim; half-day versions compress to the sandbar and Poda. One day suffices for the circuit, though photographers often return for different light and tides.

Tours and longtail charters depart Ao Nang beach, Nopparat Thara pier and Railay daily, with hotel pickup common on package tours. Krabi International Airport is the regional gateway, about 40 minutes from Ao Nang; no scheduled ferries serve the islets individually.

The day moves entirely by boat between islands, with barefoot beach landings and short swims or wades at each stop. On the islets, everything is a stroll; the sandbar crossing itself is the one walk of consequence, timed to the tide.

Ao Nang's beachfront and Nopparat Thara pier are the practical hubs, linked by songthaew to Krabi Town and by road to the airport. Railay, itself boat-access only, offers the shortest hop to Phra Nang and the islands.

The islands open to visitors in daylight hours under park rules, with tours running morning to late afternoon. Thale Waek's walkable window follows the tide rather than the clock, and rangers may limit landings at busy periods.

A Hat Noppharat Thara–Mu Ko Phi Phi National Park fee applies, collected at the islands or bundled into tour prices, at Thailand's usual higher foreigner rate. Tour costs vary by boat type and group size; agree charter prices before boarding and carry cash.

Tours typically include a picnic or boxed lunch eaten on Koh Poda, and vendors sometimes sell drinks and snacks near landing points in season. Full restaurant choice waits at Ao Nang and Railay, from beachfront seafood to southern Thai kitchens.

The post-tour meal is the culinary event: grilled Andaman seafood, gaeng som, massaman and roti in Ao Nang or Krabi Town. On the islands themselves, fresh pineapple and coconut water from vendors are the traditional refreshments.

No accommodation exists on the islets; Railay's resorts put you closest, with Ao Nang, Nopparat Thara and Klong Muang covering every budget minutes from the departure beaches. Krabi Town suits budget travellers content with a songthaew ride to the boats.

Shared longtail tours make this one of Thailand's cheapest great island days, with speedboats and private charters scaling upward. Park fees and lunch add modestly; overall a Four Islands day undercuts Phi Phi trips while delivering comparable scenery.

Beyond drink vendors, the islands offer no shopping, and park rules keep it that way. Buy sunscreen, hats and dry bags in Ao Nang beforehand, and save souvenir browsing for the mainland evening markets.

Wear the life jackets provided, watch footing on wet boat ladders and shallow coral, and respect crew guidance on currents around the sandbar as tides turn. Sun exposure is the day's stealth hazard, so reapply sunscreen and hydrate; secure phones in dry bags for landings.

Beach landings through shallows make the standard tour difficult for wheelchair users, though calm seas, short distances and helpful crews allow some assisted visits by speedboat. Travellers with limited mobility should arrange private charters and discuss landings in advance.

Guides and crews speak workable English, and briefings cover the day's plan clearly. The standard courtesies, sawasdee and khop khun with a smile, plus respectful behaviour at the Phra Nang shrine, cover the cultural bases.

Check the tide table before booking so your day includes a low-tide sandbar crossing, and choose morning departures for calmer water and lighter crowds. Private longtails buy flexibility cheaply for groups, and keeping expectations flexible in monsoon months avoids disappointment.

Pack reef-safe sunscreen, hat, swimwear, towel, dry bag and water shoes for coral-flecked shallows; cash covers park fees and vendors. A rash guard beats repeated sunscreen coats, and your own mask guarantees a snorkel fit.

These small islets absorb heavy use, so leave nothing, take only photos and stand clear of coral when snorkelling or wading. Choose operators who respect park rules and mooring buoys, use reef-safe sunscreen and keep the sandbar's fragile channel undisturbed.

Railay's beaches and climbing cliffs adjoin the circuit at Phra Nang, with Ao Nang's strip on the mainland and the Hong Islands a separate loop north. Phi Phi lies further offshore, and inland Krabi's Tiger Cave Temple and Emerald Pool balance the beach days.

The islands fall within Hat Noppharat Thara–Mu Ko Phi Phi National Park under the Department of National Parks, which levies fees and enforces landing rules. The TAT office covering Krabi province lists licensed operators and current conditions.
