What Four Islands Krabi Means

Ask for the 4 Islands tour in Ao Nang and nearly every agent will know what you mean. It is a shared or private boat day trip that links several islands and beaches off the Krabi coast. The classic route covers Koh Poda, Chicken Island (Koh Kai), Tup Island with its sandbar, and Phra Nang Cave Beach at Railay. Some operators swap a stop or reorder the day to dodge crowds or rough water. Ask for the written stop list before you pay.

Typical Stops and What You Do at Each

Treat each stop below as typical, not guaranteed. Operators adjust the order with tides, wind and boat traffic. Confirm the list with your seller.

• Koh Poda: a beach island used for swimming, snorkelling and beach time. Many boats also stop here for lunch, but check whether your tour does.
• Chicken Island (Koh Kai): named for a rock stack that resembles a chicken's head. Boats usually anchor offshore for swimming and snorkelling. Read more on the Chicken Island stop.
• Tup Island: known for a sandbar that links it to neighbouring land. Walking the sandbar depends on the tide, so it may be underwater on your day.
• Phra Nang Cave Beach at Railay: a limestone-backed beach with a cave. Some itineraries skip it, so ask whether it is on your boat's route.

Four Islands vs Hong Islands vs Phi Phi: Which Day Trip?

These three trips look similar on a tour board but feel different on the water. Four Islands is the compact option with sandbar and beach stops. Our guide to the Hong Islands day trip covers the lagoon-focused alternative. For the longer crossing, see getting from Krabi to Phi Phi. The table uses relative terms because duration and fares vary by operator.

What's Included, Costs and How to Book

Operators set their own baht prices, so confirm the fare and inclusions such as lunch, snorkel gear and hotel transfer in writing before paying. National park fees may be charged separately, so check the current rate on the national parks authority site.

Best Time, Tides and Weather Risks

Tide controls the sandbar at Tup Island and affects how close boats can anchor. A low tide gives you the walkable strip. A high tide may leave only water. Ask your seller what the tide is doing on your date and which stops it affects. Monsoon-season weather can cancel or reroute boats. Check the official Thai marine and weather forecast the day before, and expect operators to make the final call at the pier.

Shared Boat, Longtail or Private? Getting the Right Setup

A shared boat is the standard choice and gives you a fixed schedule with other guests at each stop. A private charter lets you choose timing and avoid the busiest anchorages. Our longtail boat guide explains how private hire works. An earlier departure usually means calmer water and emptier beaches, while later boats overlap with crowds already ashore. If you want to combine this trip with other islands, start from the island hopping overview and pick a second day.

Who Should Skip It, and Common Mistakes

Skip the full tour if you cannot swim, get seasick easily, travel with very young children, or want a quiet beach. A private half-day boat or a single beach day at Railay fits those needs better. Bring reef-safe sunscreen, water shoes, a dry bag, and cash for fees and extras. Pack seasickness tablets before you board, not after.

• Booking without a written stop list.
• Assuming the sandbar is always walkable.
• Leaving cash and seasickness prep to the pier.
• Choosing a shared boat when you wanted quiet.

A Day-Before Checklist for the 4 Islands Tour

Use the day before departure to confirm the practical details that can change. Ask the operator for the written 4 Islands stop list, since tides, wind and boat traffic can alter both the order and the beaches visited.

Check whether lunch, snorkel gear and hotel transfer are included. Confirm whether the national park fee is separate and bring cash for any extras. Ask specifically if Tup Island’s sandbar is expected to be walkable at your departure time.

Check the official Thai marine and weather forecast one day before you go. Operators can cancel or reroute boats when conditions are unsafe. If the forecast looks rough, ask about moving your booking instead of assuming every classic stop will be possible.

• Save the operator’s contact details and pickup time.
• Pack water shoes, reef-safe sunscreen, a dry bag and seasickness tablets before leaving your hotel.
