Krabi's headline island tours attract the biggest crowds, but the coast has dozens of smaller islands that most visitors never see. Yawasam, Talu and the beach at Bayu, sometimes spelled Buya, are among them: small outcrops of limestone and sand with clear water, shallow reef and few facilities. They sit within a short boat ride of Ao Nang, which makes them practical for a half- or full-day outing, and they offer a more relaxed experience than the busiest island circuits. The snorkelling trip we link takes you from Krabi to these islands by boat, with hotel pickup, snorkelling equipment and guidance. At each stop, you can swim along the reef, look for fish and corals, and relax on the sand. The mix of stops varies with tide and weather, but the aim is a day of easy swimming, simple food and scenery without the long transit times of Phi Phi or Koh Rok.
What you will see underwater
The reef near these islands has a spread of hard and soft corals, with parrotfish, sergeant majors, butterflyfish, wrasse and sometimes larger visitors such as sea turtles or reef sharks that keep to the deeper edges. Visibility depends on weather and plankton, with the dry season from November to April offering the clearest water. Guides keep an eye on the group and point out sights, and life jackets are available for weaker swimmers. Bring a rash vest to protect your back from the sun while you float.
On land
Talu Island has a small beach and a quiet cave nearby, which gives the day a modest sense of exploration, and Bayu Beach is a stretch of fine sand where boats pull in for lunch or a swim. The facilities are simple, and the food is usually a packed meal or a plate of rice and curry served on board. These are not resort islands, so do not expect shops or loungers. The charm is in the emptiness and the shallow water.
When it fits
Choose this trip if you have already done the Four Islands tour and want a second island day with a calmer feel. It is also suited to people with limited time, since the transit to the islands is shorter than for the big names. If you want a different flavour, the Hong Island tour offers lagoons and viewpoints, while Koh Rok is a more remote snorkelling destination with a longer boat ride.
Practical tips
Take reef-safe sunscreen, a hat, a dry bag and a change of clothes. National park fees may be extra, so carry some cash. Seas can be rough in the green season, and trips may be rerouted or cancelled, so check the terms. The shallow reef is fragile, so do not stand on corals or touch marine life. Pair this trip with a late lunch in Ao Nang and a massage, or follow it with a quiet evening rather than a heavy schedule.
Making the most of the day
Ask the crew about the plan for each stop so you can choose between swimming, exploring the shoreline and resting under the trees. Bring a waterproof camera or phone case, because the clear shallows make good photographs, and keep your fins and mask away from the corals.
Many boats provide fresh fruit and cold drinks between stops. If you are travelling with children, a snorkel vest adds confidence, and a rash vest saves the constant reapplication of sun cream. Finish the day with a shower, a long drink and an early dinner.
