Krabi Island Hopping: Best Tours, Routes & What to Actually Expect

Why Krabi Is One of Thailand's Best Island-Hopping Bases

Krabi Province covers 5,323 km² of coastline, limestone karst, and offshore islands in southern Thailand. Its position on the Andaman Sea puts it within easy reach of dozens of islands, from the famous Koh Phi Phi to the quieter Koh Hong group and beyond to Koh Lanta. Almost every island in the region is accessible as a day trip from either Ao Nang or Krabi Town pier.

The practical appeal is real: most tours operate on a roughly 6-hour format, departing around 8:00 to 8:30 a.m. and returning by early afternoon. That leaves time in the evening for Ao Nang's beach strip or Krabi Town's night market. You can comfortably run two or three different island trips across a week-long stay without repeating any destination.

The Four Islands Route: What It Is and What to Expect

The Four Islands trip is the most booked island-hopping tour in Krabi, and it is also the most frequently misunderstood. It does not go to the Phi Phi Islands. The route covers four small islands along the Ao Nang coastline: Tup Island (Koh Tup), Mor Island (Koh Mor), Chicken Island (Koh Kai), and Poda Island (Koh Poda). The route also includes a stop at Phra Nang Cave Beach on the Railay Peninsula.

The highlight for most visitors is the sandbar between Tup and Mor islands, known locally as Talay Waek (sometimes translated as the Separated Sea). At low tide, a narrow strip of sand rises from the water connecting the two islands, and visitors wade between them in knee-deep water. Timing your tour to hit low tide at the sandbar makes a real difference to the experience. It is worth checking tide tables or asking your operator before booking. Phra Nang Beach is consistently rated among the finest beaches on the route, with dramatic limestone cliffs dropping to white sand and clear water.

• Koh Poda White sand, clear snorkeling water, and good shade. One of the better spots to spend time rather than rush through.
• Koh Kai (Chicken Island) Named for its rock formation. Shallow reef around the island makes it the main snorkeling stop on most itineraries.
• Talay Waek sandbar (Koh Tup/Koh Mor) Only visible at low tide. Crowded at peak season (December to February), but still worth experiencing.
• Phra Nang Cave Beach A limestone cave with a small shrine, tucked into the cliff face at the southern end of the Railay Peninsula.

The Hong Islands Circuit: The Better Choice for Most Visitors

The Hong Islands (Koh Hong group) sit northwest of Ao Nang and are administered under Than Bok Khorani National Park. A typical tour covers three islands: Koh Hong itself, Koh Lao Lading, and Koh Pakbia, with some operators also including Hong Lagoon. This route draws a slightly different crowd to the Four Islands: fewer large group packages, more snorkeling focus, and genuinely impressive lagoon scenery. If the Than Bok Khorani National Park name means nothing to you, this is the park that contains some of Krabi's most dramatic enclosed lagoons and mangrove-fringed channels.

Shared speedboat tours to the Hong Islands run around ฿1,500 per adult for the full day trip, with departures from Ao Nang around 8:00 to 8:30 a.m. and returns around 3:00 p.m. The national park fee is additional: ฿300 for foreign adults, ฿150 for foreign children aged 4 to 14, payable in cash on arrival. These are listed prices and can vary by operator and season, so verify when booking.

Other Routes Worth Knowing

Beyond the two main circuits, Krabi's island-hopping options extend in several directions. A dedicated Phi Phi day trip from Ao Nang takes about 45 minutes by speedboat and is sold separately from the Ao Nang coast routes. The itinerary typically includes Maya Bay (currently operating under timed-entry restrictions), Pileh Lagoon, Monkey Beach, and snorkeling stops around the archipelago.

For a longer commitment, Koh Lanta is reachable as a day trip but more logically visited on a two-night stay. The island sits about 70 km south of Krabi Town and has its own snorkeling routes through the Mu Ko Lanta National Park. If you want proper offshore reef diving rather than snorkeling, the Koh Haa dive sites south of Koh Lanta are considered among the best in the region. See our Krabi diving guide for detail on those routes.

• Bamboo Island day trip Often combined with Phi Phi tours. Small, less developed, with shallow water good for swimming. Recommended if you want a quieter alternative to the main Phi Phi beaches.
• Koh Yao Noi / Koh Yao Yai Accessible from Krabi Town pier by ferry. Less developed than most Krabi islands, with a more local feel. Worth the trip if you have a full day and want to escape tour-group density.
• Railay by longtail Not an island (it's a peninsula), but accessible only by boat and worth combining with a broader day on the water. Longtails from Ao Nang run regularly and cost around ฿100 per person.

Longtail vs Speedboat: Choosing the Right Vessel

The choice between longtail boat and speedboat is not just about budget. It shapes the entire day. Speedboats cover larger distances in less time, making them necessary for Phi Phi, Koh Haa, and any destination more than 30 km from your departure point. They are also significantly rougher in choppy water, and the noise is constant. Anyone prone to motion sickness should take medication beforehand, regardless of how calm the sea looks when you depart.

Longtail boats are slower, lower, and often cheaper. For the Four Islands route, many operators still run longtail tours, and for short hops along the Ao Nang coast, the lower speed is not a meaningful disadvantage. The open-sided design also makes photography easier. The trade-off is that they offer zero protection from sun or spray, and in swell they can be uncomfortable. Bring waterproof bags for electronics regardless of which boat type you use.

Booking, Pricing and Avoiding the Common Mistakes

The majority of Krabi island-hopping tours can be booked through beachside operators in Ao Nang, through your hotel, or via platforms like GetYourGuide and Viator. Walk-in prices from street-level operators in Ao Nang are sometimes lower than pre-booked online prices, but the difference shrinks in peak season (December to February) when boats fill up days in advance. If your dates are fixed, pre-book.

Read what is included before paying. National park fees, snorkeling gear rental, hotel pickup, and lunch are handled differently by different operators. Some tours that appear cheap at ฿900 to ฿1,200 per person end up costing significantly more once you add the park fee, equipment rental, and transfer. A tour listed at ฿1,500 with pickup, gear, and park fees included can represent better value.

For a broader sense of how to structure time across multiple trips, the 5-day Krabi itinerary maps out how to combine island hopping with mainland activities like the Emerald Pool and Tiger Cave Temple without burning out.

• Confirm the exact islands included in your tour. Some operators quietly drop a stop if weather or timing makes it inconvenient.
• Ask about group size. Shared tours on a 40-person speedboat feel very different from a 12-person boat.
• Check the cancellation policy before paying. In shoulder season (April to May, October to November), morning departures can be cancelled due to sea conditions.
• If snorkeling is your priority, ask specifically which stops have the best coral. Koh Poda and Koh Kai on the Four Islands route are the better options; the sandbar stop at Talay Waek has little snorkeling value.
• Sunscreen with UV filters is essential but choose reef-safe formulas. Several national park areas have restrictions on chemical sunscreens.
