Mor Island Krabi Guide: How to Visit, Best Things to Do & Travel Tips

Mor Island is also known as Koh Mor, a tiny, picturesque islet in the Krabi province of Thailand. This small limestone island is part of the famous Talay Waek area. During the low tide, it creates a natural sandbar that connects Chicken Island and Tub Island. You can walk across the ocean from one island to another on foot. It is one of the offbeat places to visit in Krabi. Its clear turquoise waters, coral-rich seabed, and scenic limestone surroundings make it a popular stop on your Krabi tour packages.

Travellers come here not just for the views but also to enjoy swimming, snorkelling, and walking along the magical sandbar that appears between the islands. With its calm atmosphere and incredible natural setting, Mor Island offers a peaceful tropical escape and a chance to witness one of Krabi’s most remarkable coastal landscapes.

Despite its small size, Koh Mor and its immediate surroundings offer a satisfying range of activities for a full-day trip.

1. Walk the Talay Waek Sandbar

One of the best things to do in Krabi is to witness the Talay whale at Koh Mor. At low tide, the seabed between the islands is revealed as a thin, white sand strip. You can wade or walk along it. With the calm Andaman Sea on both sides, framed by the limestone silhouettes of surrounding islands, it is a perfect place to capture Instagram-worthy pictures.

2. Snorkelling in Crystal-Clear Waters

The surrounding waters of Koh Mor are shallow, calm, and clear, making them ideal for snorkelling, even for beginners and families with children. The coral reefs around the island are home to a vivid range of tropical fish, such as parrotfish, clownfish, angelfish, and much more. Visibility is particularly good during the dry season months.

3. Swimming and Beach Relaxation

The beaches around Koh Mor are calm and clean, with the shallow Andaman waters staying at a warm 28–32°C year-round. The island itself is relatively undeveloped, meaning the beach experience is natural and peaceful.

4. Viewpoint Hike on Koh Tup

The neighbouring Koh Tup has a small hilltop viewpoint accessible via a short trail. The climb is brief but rewarding, offering panoramic views across the archipelago, the sandbar below, and the dramatic limestone karsts of the Krabi coastline in the distance.

5. Island-Hopping to Koh Poda and Koh Kai

Koh Mor is almost always visited as part of a wider island-hopping experience. The popular 4 Islands Tour Thailand includes Koh Tup and Koh Mor, Koh Kai (Chicken Island), Koh Poda, and Phra Nang Cave Beach at Railay, giving you a full, varied day across the most scenic corners of the Krabi coastline.

Reaching Koh Mor is quite easy, as the island is part of the famous island-hopping routes near Krabi. The island lies within the popular Talay Waek area, where visitors can walk between islands during low tide.

Join a Four Islands Tour

The most common way to reach Koh Mor is by joining the Krabi Four Islands Tour. These tours usually depart from Ao Nang Beach and include stops at nearby islands like Chicken Island, Tub Island, and Poda Island. I

• Travel time: about 15–20 minutes by longtail boat from Ao Nang
• Tour cost: around ฿400–฿800 (₹950–₹1,900) depending on the boat type

Hire a Private Longtail Boat

For a more flexible trip, you can rent a private longtail boat from Ao Nang Beach or Railay Beach. This option lets you explore the islands at your own pace and visit during the best low-tide hours when the sandbar appears.

Speedboat Island-Hopping Tour 

Many operators also offer speedboat tours from Ao Nang and nearby areas. These are faster and ideal if you want to visit multiple islands in a shorter time.

There is no direct entrance fee for Koh Mor itself, but national park fees may apply depending on which islands are included in your itinerary.

Best Seasons

• November–April (Best Season): This is the best time to visit Karbi and Koh Mor. Expect sunny skies, calm seas, and temperatures around 25–32°C, perfect for island hopping and snorkelling.
• April–June (Hot Season): Temperatures rise above 33°C, with higher humidity. Boat tours still operate, and April’s Songkran brings lively celebrations. Hotel prices are often 30–40% cheaper than in peak season.
• May–October (Rainy Season): The monsoon brings occasional heavy showers and rougher seas, sometimes affecting boat trips. However, the islands are greener and less crowded, and travel deals are easier to find.

Best Time of Day

• Early morning (before 9:30 AM) for the calmest seas, fewer tour boats, and the best chances of catching low tide
• Check tide charts in advance if walking the sandbar is your priority; tide times shift daily.
