map The 8 Underrated Islands to Discover

1. Koh Kood (Ko Kut): The Pristine Paradise

Often hailed as Thailand's answer to the Maldives, Koh Kood, located in the Trat province near the Cambodian border, is a sanctuary of unspoiled beauty. It's the fourth-largest island in Thailand but remains remarkably underdeveloped, preserving its lush rainforests, pristine white-sand beaches, and crystal-clear turquoise waters. Unlike its bustling neighbor Koh Chang, Koh Kood maintains a tranquil, laid-back atmosphere.

Location & Accessibility

Getting to Koh Kood requires a bit more effort, which contributes to its untouched charm. The primary gateway is Laem Sok Pier in Trat province. From Bangkok, you can take a bus or fly to Trat Airport (TDX) [Source: Thai Airways, Bangkok Airways]. From Trat town, a taxi or songthaew (shared pickup truck) will take you to Laem Sok Pier. Several ferry operators, including Boonsiri High Speed Ferries and Koh Kood Express, offer daily services to the island. Travel time from Laem Sok to Koh Kood ranges from 1 to 2 hours, depending on the boat type. Prices typically range from 350-600 THB for a one-way ticket, based on current operator websites [e.g., Boonsiri Ferry].

Why It's Underrated

• Unspoiled Nature: Dense jungles, spectacular waterfalls (Klong Chao, Huang Nam Keaw), and mangrove forests.

Budget options start around 500 THB for basic fan rooms [Source: Agoda, Booking.com estimates].

Dining & Nightlife

Dining is focused on fresh seafood and authentic Thai cuisine. Many resorts have excellent restaurants, but local eateries offer more affordable and traditional options. Try the seafood BBQ at one of the small beachfront shacks. Nightlife is minimal, typically confined to a few quiet beach bars, perfect for stargazing. Hyper-local tip: Visit “Noochy Seafood” near Klong Chao for exceptionally fresh and affordable grilled fish.

Are there ATMs on Koh Libong or Koh Sukorn?

No, there are generally no reliable ATMs on Koh Libong or Koh Sukorn. These islands are very underdeveloped in terms of tourist infrastructure. It is critically important to withdraw sufficient Thai Baht in a larger town like Trang or Krabi before you travel to these islands. Most local businesses operate on a cash-only basis.

What's the best way to get around Koh Lanta?

The best way to get around Koh Lanta is by renting a scooter. Prices are typically 200-350 THB per day. This allows you the freedom to explore its long beaches, Lanta Old Town, and Mu Ko Lanta National Park at your own pace. Alternatively, you can use songthaews (shared pickup truck taxis) or motorbike taxis, but these can add up in cost for extensive travel.

Can I find vegetarian or vegan food on these smaller islands?

Yes, finding vegetarian or vegan food is generally possible on these smaller islands, though options might be more limited than in major cities. Most Thai dishes can be made vegetarian or vegan by requesting 'jay' (vegan) or 'mangsawirat' (vegetarian) and asking to omit fish sauce (nahm pla) and oyster sauce (nahm man hoy). Look for dishes like 'Pad See Ew Jay', 'Pad Thai Jay', 'Gang Keow Wan Jay' (green curry), or 'fried rice with vegetables'.

Is Koh Phayam good for surfing?

Yes, Koh Phayam is one of the few islands in Thailand that offers decent surfing conditions, particularly during the monsoon season (May to October). The waves are generally mellow, making it suitable for beginners and intermediate surfers. Aow Yai (Big Bay) is the main surf spot, with several surf schools and board rental shops available during the season.
