Want to get away from the hustle and bustle of Maya Bay? Hit the Loh Samah Bay, Krabi. Nestled quietly along the eastern edge of Ko Phi Phi Leh, this bay is famous for its crystal-clear turquoise waters. As your longtail boat slows near the limestone cliffs, you can see the coral garden swaying beneath the surface. With vibrant coral reefs and plenty of marine life, Loh Samah is an ideal spot for snorkelling and swimming. As the dusk wraps around, the Samah beach sparkles with electric blue flashes. This guide covers top activities, ways to reach them, what to dine on, the best time to visit and must-know things for a memorable 2026 trip.

Nestled on the southern tip of Phi Phi Leh, Loh Samah Bay is one of Thailand's most breathtaking hidden coves. It is also known as Loh Sama, which is also a part of the protected Hat Noppharat Thara–Mu Koh Phi Phi National Park. It is a small rocky islet that sits at the centre of Krabi. Thus, it can only be reached by boat, lending it an air of exclusivity even during the height of tourist season.
This bay is divided into two distinct snorkelling areas, while a narrow canyon at the northern end conceals a tiny hidden beach backed by mangroves. Its dramatic limestone cliff, shallow water and diverse marine life make this one of the best places to visit in Thailand for beginner-friendly snorkelling and swimming. If you're lucky enough, you can also enjoy the view of glowing plankton in the surrounding waters. It sits close to the famous Maya Bay but offers a more intimate and less chaotic atmosphere. The waters here supported generations of local fishermen who revered the bay's natural abundance. Today, it holds equal importance as an ecological nursery for reef fish, invertebrates, and coral polyps.

Loh Samah punches well above its size. Here is what makes it genuinely unmissable on any Phi Phi itinerary.
Float above coral reefs and spot colourful fish, parrotfish, blue tangs, and occasional reef sharks in clear, shallow waters. Snorkelling in the shallow waters is one of the best things to do in Krabi. Most snorkelling areas at Loh Samah sit in 2–5 metres of water, making them ideal for beginners. Visibility often reaches 15–20 metres during the dry season, where you can see parrotfish, clownfish, blue tangs, and occasional blacktip reef sharks.
Explore dramatic limestone walls, underwater canyons, sea fans, and swim-through passages ideal for intermediate and advanced divers. Several dive operators based on Phi Phi Don (including Princess Divers and Blue View Divers) run guided dives to this site.
Experience glowing plankton, nocturnal marine life, moray eels, and crustaceans after sunset. Night dive packages typically depart from Tonsai Pier on Phi Phi Don around 7–8 pm. If you are visiting Loh Samah, this is a worthwhile activity for your Krabi tour packages.
If you prefer to stay dry, hiring a long-tail boat is the best thing to do in Loh Samah Bay. Take a cruise around the bay for scenic limestone cliff views and marine spotting from the boat.
Enjoy calm waters and unwind on a small hidden beach accessible during low tide. Families with young children have consistently praised Loh Samah for how calm and safe the waters feel compared to more exposed beaches.

November to April is the best time to visit Krabi's Loh Samah Bay. It is the peak dry season when the seas are calm, skies are clear, and visibility underwater reaches 20+ metres. This is an ideal time for snorkelling, diving, and photography. For the sweet spot of good weather, manageable crowds, and everything open, visit in late October through early December.
Note: Loh Samah Bay and the broader Phi Phi Leh island close annually from 1 August to 30 September to allow the reef and marine life to recover from tourist pressure.
Reaching Loh Samah Bay is part of the adventure. Since it’s located on Ko Phi Phi Leh, there are no roads or direct land access; the only way to get there is by boat.
If you are staying in Krabi, especially Ao Nang or Railay Beach, the easiest way to reach Loh Samah Bay is by booking a Phi Phi Islands day tour. Speedboats take around 45–60 minutes to reach the area.
You can join a full-day Phi Phi Islands speedboat tour, which usually takes about 1 to 1.5 hours, depending on sea conditions. Loh Samah Bay is included as a snorkelling stop on most standard Phuket itineraries.
If you are already staying on Koh Phi Phi Don, you can hire a private longtail boat to reach Loh Samah Bay in about 15–20 minutes. This option gives you more flexibility in timing and allows you to avoid peak tour hours.

Loh Samah Bay pairs perfectly with a wider loop of Phi Phi Leh and the surrounding islands. All of the following are easily combined in a single-day tour.
