Best Beaches in Koh Samui: A Guide to Choosing the Right Beach

Koh Samui is one of Thailand’s most popular island destinations, known for its white-sand beaches, turquoise waters and different coastal experiences. Unlike some islands where beaches feel similar, each area of Koh Samui has its own atmosphere, from the lively energy of Chaweng to the peaceful surroundings of Maenam and Choeng Mon.

Choosing the right beach can shape your entire holiday. Some travellers prefer to stay close to restaurants and activities, while others look for a quieter escape away from crowds.

For those who want to enjoy Koh Samui’s beaches while staying in a more private setting, Mantra Samui Resort offers a hillside retreat in Mae Nam with panoramic ocean views overlooking the coastline and easy access to explore the island’s beaches.

Chaweng Beach: The Most Popular Beach in Koh Samui

Chaweng Beach is Koh Samui’s most famous beach and one of the easiest places to stay for first-time visitors. Stretching for around 6–7 kilometres along the east coast, it offers soft sand, clear water and a wide range of restaurants, beach bars and activities.

The main advantage of Chaweng is convenience. Everything is close by, from dining and shopping to nightlife and water activities. However, this also means it is one of the busiest areas on the island, especially during peak travel periods.

The southern part of Chaweng offers a quieter atmosphere compared with the more active northern section, making it a better choice for travellers who want access without being directly in the busiest area.

• Location: Chaweng Beach, Bo Put, Koh Samui

• Distance from Mantra Samui Resort: Around 9 km (15 minutes by car) 

• Best for: First-time visitors, nightlife, activities and travellers who want everything nearby.

Bophut Beach: The Best Choice for Dining and Evening Atmosphere

Bophut Beach offers a different experience from Koh Samui’s larger beach areas. Located on the northern coast, its main attraction is not only the beach itself but the nearby Fisherman’s Village, where travellers can find restaurants, cafés and a relaxed waterfront atmosphere.

The beach has a calmer, more boutique feeling compared with Chaweng. While it may not offer the island’s best swimming conditions in every area, it is an excellent choice for travellers who enjoy sunset walks, seaside dining and exploring local shops.

• Location: Bophut Beach, Bo Put, Koh Samui

• Distance from Mantra Samui Resort: Around 3 km (5 minutes by car)

• Best for: Couples, food lovers and travellers who enjoy a relaxed evening atmosphere.

Lamai Beach: A More Relaxed Alternative to Chaweng

Located south of Chaweng, Lamai Beach offers many of the same benefits with a slower pace. The beach stretches for around 4 kilometres and provides plenty of space for swimming, relaxing and enjoying the coastline.

Lamai has a good balance between convenience and relaxation. There are restaurants, cafés and shops nearby, but the atmosphere feels less crowded than Chaweng. The southern end of Lamai is also home to Hin Ta Hin Yai Rocks, one of Koh Samui’s most recognisable natural landmarks.

For couples who want a beautiful beach with enough dining options while avoiding a busier atmosphere, Lamai is a popular choice.

• Location: Lamai Beach, Maret, Koh Samui

• Distance from Mantra Samui Resort: Around 16 km (20 minutes by car) 

• Best for: Couples, longer stays and travellers seeking a balance between relaxation and convenience.

Choeng Mon Beach: A Peaceful Beach for Swimming and Relaxation

Choeng Mon Beach is located on the northeastern side of Koh Samui and is known for its sheltered bay, soft sand and calmer waters. Its quieter setting makes it one of the island’s better choices for travellers who prefer a more peaceful beach day.

Compared with Chaweng and Lamai, Choeng Mon has fewer crowds and a more private resort atmosphere. The calm water also makes it suitable for relaxed swimming and enjoying the sea at a slower pace.

• Location: Choeng Mon Beach, Bo Put, Koh Samui

• Distance from Mantra Samui Resort: Around 10 km (20-25 minutes by car) 

• Best for: Couples, families and travellers looking for a quieter coastal escape.

Maenam Beach: A Quiet Base Away from the Crowds

Located on Koh Samui’s northern coast, Maenam Beach offers a slower and more peaceful side of the island. The long sandy coastline, views towards Koh Phangan and relaxed surroundings make it ideal for travellers who prefer space and privacy.

Unlike the busier eastern beaches, Maenam has a more laid-back atmosphere with fewer crowds and a slower daily rhythm. It is a great choice for couples who want to enjoy the island’s natural beauty while staying away from the busiest tourist areas.

This is also where Mantra Samui Resort is located, offering a different way to experience Koh Samui — staying above the coastline rather than directly on the beach while enjoying panoramic ocean views and easy access to explore nearby beaches.

Location: Maenam Beach, Mae Nam, Koh Samui

Distance from Mantra Samui Resort: Around 3 km (5 minutes by car) 

Best for: Couples, wellness travellers and those looking for a peaceful island stay.

A Hillside Retreat Near Koh Samui’s Beaches

Located close to the island’s northern coastline, the resort is around 2-3 km from Maenam and Bophut Beach, while popular beaches such as Choeng Mon, Chaweng and Lamai can be reached easily by car for a day of exploring.

After exploring the island, guests can return to panoramic ocean views, relax at Jai Spa, enjoy wellness experiences through SAOL Wellness Retreat, or unwind by the infinity pool. With spacious rooms, an infinity pool, and an adults-only atmosphere, Mantra Samui provides a peaceful base to discover Koh Samui while enjoying a slower island escape.
