The 10 Most Beautiful Beaches in Koh Samui (2025-2026): choose the right beach for your vacation style

Koh Samui (often simply called Samui) is one of Thailand’s easiest islands for a dream vacation: postcard beaches, calm bays, lively areas, great food, and day trips to nearby islands. This 2025-2026 guide highlights 10 must-see beaches with practical tips (vibe, access, best time of day, snorkeling). And if you want to add more action: Koh Phangan for parties (including the famous Full Moon Party) and Koh Tao for diving and snorkeling.

Best time to visit Koh Samui for beach days

For the best “turquoise water” moments, focus on calmer sea conditions and early mornings for clearer visibility. High season brings better availability of tours and services, but also higher prices—book beachfront stays early for popular areas like Chaweng and Lamai.

Pick the right beach (based on your travel style)

Party & nightlife: Chaweng (bars, beach clubs).
Balanced & convenient: Lamai.
Postcard bay + snorkeling: Silver Beach / Crystal Bay.
Quiet sunsets: Lipa Noi.
Local charm: Bophut / Maenam.
