Four Islands Tour from Krabi: Is It Worth It?

← Home

The Four Islands Tour is the single most-booked day trip out of Ao Nang, and for good reason: it’s cheap, it’s easy to arrange, and it packs dramatic limestone scenery, a bit of culture, and decent snorkeling into a few hours without needing any diving certification. It’s also, by a wide margin, the most crowded boat trip in the area. This guide covers exactly what’s on the itinerary, what it actually costs, and an honest look at whether it’s worth your one boat-trip day in Krabi or whether you’d be better off with something else. For general orientation to the region, see our Krabi travel guide.

What’s Actually on the Four Islands Tour

Phra Nang Cave Beach

Technically the tip of the Railay peninsula rather than a true island, this stop centers on a small cave shrine where local fishermen leave carved wooden offerings to a legendary princess spirit, asking for fertility or a safe voyage, a genuine piece of local culture rather than just a photogenic beach. It’s also one of the most crowded stops on the itinerary, since day-trippers, Railay-based longtail charters, and climbers heading to nearby walls all converge here at once; more than one visitor has felt the standard 20-30 minute stop is too rushed for what the place actually offers. Our Railay Beach guide covers the peninsula in more depth if you’d rather visit on its own terms.

Chicken Island (Koh Gai)

Named for a rock formation that resembles a chicken’s head, this is a boat-based snorkel stop rather than a place with a real beach landing on most itineraries. Opinions on the snorkeling here vary quite a bit between visitors, some call it unremarkable, others describe genuinely good visibility and marine life, which likely comes down to conditions on the day rather than the site itself being consistently good or bad.

Tup Island (Koh Tup) and the Sandbar

Tup Island connects to Chicken Island by a narrow sandbar, locally called Thale Waek, “the sea that splits,” that’s walkable only at low tide and submerges completely at high tide. This is genuinely tide-dependent, not something you can request on a specific tour time, so whether you get the classic straddle-two-islands photo depends on when the tide happens to be low on your travel date.

Poda Island (Koh Poda)

The anchor stop on almost every itinerary, and consistently described as having the clearest water of the four. Lunch (usually a buffet or boxed meal) is served here, and many operators offer paddleboard or kayak rental as an add-on. Facilities are basic, expect squat toilets rather than resort-style amenities.

Longtail vs. Speedboat: Which to Book

Both formats run the same basic itinerary, but the experience and price differ meaningfully.

Treat all of these as rough, seasonal ranges rather than fixed prices, consistent with how pricing is presented elsewhere on this site, since rates shift with demand and season. A private charter costs more per boat but, split between three to five people, can land close to a shared speedboat ticket while giving you control over which stops you linger at.

What It Costs, and What’s Included

Most tours include hotel pickup and drop-off (Ao Nang, Krabi Town, and Klong Muang are standard; Railay and Tonsai sometimes need a separate pier meeting point), snorkel gear, life jackets, lunch, and a guide. Almost none of them include the national park entrance fee, which is paid in cash on-site. Here sources genuinely disagree on the current figure: some list 200 THB for foreign adults (100 THB for children), others list 400 THB (200 THB for children). The higher figure appears to trace to a separate fee introduced for the Phi Phi side of the same national park rather than this Ao Nang-side zone, but park fees can and do change, so budget for the higher end and treat the exact number as unconfirmed until you pay it on the day.

Tide, Timing, and Crowds

Because the Tup-to-Chicken Island sandbar only appears at low tide, check a tide chart if that specific stop matters to you, no tour operator can guarantee it regardless of what time slot you book. Overcrowding is the single most consistent complaint about this tour across independent reviews: dozens of boats anchored close together at Poda Island, hundreds of visitors passing through Phra Nang in a single morning. Booking an early departure or a private charter are the two realistic ways to reduce how much of the trip you spend around other tour groups. Our Best Time to Visit Krabi guide covers the seasonal picture in full, but the short version for boat tours specifically: November through April is calmest and most reliable, while September and October see the highest rate of cancellations due to rough seas.

Is It Actually Worth It? An Honest Take

Mostly yes, with real caveats. The scenery is genuinely dramatic, the water at Poda is genuinely clear, and for non-divers, families, or anyone without their own boat access, it’s an easy, inexpensive way to see several of Krabi’s best-known islands in a single morning or afternoon. The honest downsides are real too: a rushed schedule at each stop, inconsistent snorkeling quality, and enough boat traffic that “peaceful island getaway” isn’t quite the right expectation to bring. At least one detailed traveler account has also documented visible litter on Poda’s beach despite entrance fees being collected, worth knowing going in rather than being surprised by. If crowding is your main concern, a private longtail charter, or considering the Hong Islands tour instead (see below), are both worth weighing against the standard shared Four Islands trip.

How It Compares to Krabi’s Other Boat Tours

The Hong Islands tour, a separate marine park experience further from Ao Nang, trades some of the Four Islands’ convenience for a more leisurely pace, a genuinely striking hidden lagoon, and shallow beach-entry snorkeling that suits beginners and kids well, at the cost of a longer boat ride to get there. A 7 Islands Sunset Cruise covers the same four core stops but extends into the evening with a few additional islands, a fire show, and night snorkeling for bioluminescent plankton, a good option if you’d rather have the atmosphere of a longer day than the efficiency of a half-day trip. If your priority is ticking off Krabi’s most iconic single day trip in the shortest time, Four Islands remains the standard choice; if avoiding crowds matters more than checking a box, Hong Islands is worth serious consideration instead.

Coral Bleaching Closures: What’s Still Restricted

In May 2024, Thai park authorities temporarily closed snorkeling and diving at several sites, including parts of Chicken Island and Koh Poda, after a survey found coral bleaching linked to elevated sea temperatures. Reporting from spring 2025 indicates most of these sites, including the northern and eastern sides of Chicken Island and northern Koh Poda, have since reopened under stricter no-anchoring, no-touching rules, while one specific zone (the western side of Chicken Island) has remained closed to protect more fragile coral. Since conservation measures like this can change again with conditions, confirm current status with your tour operator before you go rather than assuming every snorkel stop on the standard itinerary is open.

Practical Tips for Your Four Islands Day

Bring reef-safe sunscreen, a hat, and a waterproof bag for your phone and valuables, since you’ll be getting on and off boats repeatedly. Pack extra drinking water beyond what’s provided. Life jackets are standard equipment on these tours; if you’re not a confident swimmer, say so before boarding rather than assuming a policy will catch it for you, since a formal minimum-swimming-ability requirement isn’t consistently enforced across operators. And bring cash in small denominations for the park entrance fee, since it’s collected on-site rather than folded into most tour prices.
