If you're craving a peaceful escape close to Bangkok, with fewer crowds and 100% pure nature, then Koh Kham is calling your name. This small island, located in Sattahip District of Chonburi Province, is under the care of the Royal Thai Navy, which has helped preserve its pristine condition. There are no permanent structures, no resorts, and no shops here – just soft sand, crystal-clear sea, and serene surroundings that make you feel like you've stepped into another world.

When people think of beaches near Bangkok, names like Koh Larn, Koh Si Chang, or Bang Saen often come to mind – and for good reason. These places are well-known and well-loved. But what many don’t realize is that there’s another hidden island quietly waiting to be discovered: Koh Kham. It's a small, charming island within the naval base area of Sattahip in Chonburi. Over the past few years, it's been gaining more attention and is now becoming a favorite spot for chill travelers in 2025 – all thanks to its raw, unspoiled beauty.

Even without flashy promotions or viral travel reviews, Koh Kham has quietly made its mark. Its calm, natural vibe has captured the hearts of nature lovers, earning it the reputation as a beloved hidden island. Once you’ve been, chances are… you’ll fall in love and want to return.

The waters around Koh Kham are so clear you can see straight to the sandy bottom—even when you're only ankle-deep! Tiny fish swim around your feet, creating a magical scene perfect for snorkeling. You don’t have to be a pro diver to enjoy it here. The coral reefs remain beautifully intact, thanks to strict environmental protection, offering visitors a glimpse of nature in its purest form.

Koh Kham’s beaches are silky smooth with no litter in sight. With a daily visitor cap of around 300 people (as of 2025), the beach remains uncrowded and serene. It’s ideal for reading, relaxing under the sun, or taking barefoot strolls along the shoreline—a perfect minimalist retreat.

No hotels. No cafés. No honking horns or beach vendors. Just the sound of nature—gentle sea breeze, waves lapping the shore, and the soothing rhythm of your own heartbeat. It’s the ideal setting for a digital detox, romantic getaway, or peaceful solo retreat.

Koh Kham is a protected area managed by the Royal Thai Navy. Environmental rules are taken seriously:
❌ No littering (you must take all your trash back)
❌ No collecting shells, corals, or marine life
❌ No sunscreen with oxybenzone or octinoxate (which harm coral reefs)
✅ All visitors receive a short briefing on marine etiquette before visiting

Because travelers who’ve been there can’t help but share their experiences—especially nature lovers and backpackers who seek places that are quiet, simple, and genuinely beautiful. If you’re tired of overcrowded beaches and want a true slow-travel vibe, pin Koh Kham on your travel list!

Koh Kham is a dream for ocean lovers. Its shallow coral reefs are rich and thriving, and the crystal-clear waters allow you to see schools of colorful fish—like clownfish, butterflyfish, and parrotfish—without diving deep. It’s beginner-friendly and safe for kids.
Snorkeling gear is available to rent on the mainland or you can bring your own. (Eco-friendly gear is highly recommended—avoid chemical-based masks.)

This long wooden bridge stretching out into the sea is Koh Kham’s #1 landmark. Designed for sightseeing and photo ops, it offers panoramic views of the ocean with stunning blue-to-green gradients.
