What are the Best Islands for an Island-Hopping Excursion from Koh Samui?

Thailand is one of the best-known countries of South East Asia and is among the top ten bucket list destinations, popular among travellers. There is much to see and experience here. Many travellers visit areas like Koh Samui in Thailand to both experience this authentic feel of the environment as well as to explore nearby islands that are equally captivating. Whether you're in search of world-class snorkelling, laid-back beach life, or unspoilt marine parks, Koh Samui is the perfect launchpad for unforgettable island adventures and island-hopping excursions. Take a closer look at the best nearby islands you can explore from Koh Samui, and why island hopping should be at the top of your holiday checklist.

Koh Phangan – More Than Full Moon Fever

Just a 30-minute boat ride north of Samui lies Koh Phangan, an island globally known for its Full Moon Party (Which is an all-night party that happens during the full moon) but has so much more than its party persona. Beyond the beach raves, there’s a rugged, unspoilt charm to this island, with jungle-covered mountains, peaceful temples, and secluded coves like Haad Yuan and Than Sadet. The journey here often starts with a private longtail boat or speedboat from Samui’s northern piers, which are conveniently close for guests staying in resorts like NH Collection Samui Peace Resort. Whether you're keen on snorkelling, yoga retreats, or a lazy beach day far from the crowds, Koh Phangan delivers a rewarding mix of adventure and calm.

Koh Tao – The Diving Capital of the Gulf

About 90 minutes away by ferry, Koh Tao is a diver’s dream. The waters here are among the clearest in Thailand, and the underwater ecosystem teems with life, ranging from graceful sea turtles to colourful coral reefs and shimmering schools of fish. You don’t need to be PADI-certified to enjoy Koh Tao’s aquatic wonders. Expert-led snorkelling excursions that cater to all skill levels can be engaged in if this is what you like. The journey to Koh Tao is as scenic as the island itself, and many day tours depart early from Koh Samui’s main harbours, allowing you to return just in time for a sunset cocktail back at your resort.

Ang Thong National Marine Park – Thailand’s Hidden Eden

If there’s one island-hopping destination that deserves an entire day to itself, it’s none other than Ang Thong National Marine Park. This is a well-protected archipelago and certainly feels untouched by time. With its towering limestone cliffs, dense jungle, and glimmering emerald lagoons, this is a paradise to visit. A day trip here might involve some sea kayaking through caves, climbing up to the breathtaking viewpoint on Koh Wua Talap, or simply swimming in the crystal-clear waters off Koh Mae Koh. While many tour boats depart from Nathon or Bangrak, some of the best resorts in Koh Samui offer private or semi-private excursions, including early access before the crowds arrive.

Koh Madsum and Koh Taen – Rustic Simplicity

Often overlooked in favour of their better-known neighbours, Koh Madsum and Koh Taen are two of the closest islands to Koh Samui, located just south of the main island. Both are ideal for half-day trips, making them perfect for travellers who prefer shorter excursions without compromising on beauty. Koh Madsum is famous for its free-roaming beach pigs, which have become a quirky but beloved attraction that’s an Instagram staple. Its quiet shores are ideal for picnics, paddle boarding, or simply soaking in the island vibe. Nearby Koh Taen, by contrast, is more about snorkelling and exploring mangrove forests. The calm waters and rustic charm offer a glimpse into island life before the advent of mass tourism.

Tips for Seamless Island Hopping

Island hopping around Koh Samui is generally easy to plan, but a few travel tips can make your excursions even more enjoyable:

Book in Advance: Popular tours to Ang Thong and Koh Tao fill up fast during peak season.

Pack Smart: Bring reef-safe sunscreen, a dry bag, water shoes, and a sarong or light towel.

Consider Private Charters: While group tours are budget-friendly, private charters offer flexible schedules and more privacy, which is ideal for honeymooners or families.
