Tucked away off the southern coast of Cambodia, Koh Tonsay—more affectionately known as Rabbit Island—is one of the country’s best-kept secrets. Just a short boat ride from the quiet town of Kep, this peaceful tropical paradise remains untouched by mass tourism. With its gentle waves, swaying palms, and barefoot lifestyle, Koh Tonsay is ideal for travelers seeking an escape into nature, solitude, and authentic Cambodian coastal charm.

If you’re looking for a destination that offers rustic simplicity with warm local hospitality, Rabbit Island deserves a top spot on your itinerary. This guide provides everything you need to know before visiting Koh Tonsay, including how to get there, what to expect, and why it’s an unforgettable addition to any Cambodia tour package.

Where Is Koh Tonsay Located?

Koh Tonsay lies about 4.5 kilometers (roughly 2.8 miles) south of Kep, a sleepy seaside town near Cambodia’s border with Vietnam. The island is part of Kep Province and can be seen from the mainland shoreline on a clear day. It takes about 20–30 minutes by boat to reach the island from the main pier in Kep.

Despite its growing reputation, Rabbit Island is still relatively off-the-radar compared to Cambodia’s more famous destinations like Phnom Penh or Siem Reap. Its location near the Vietnam border also makes it a convenient stop for those combining Vietnam tours with Cambodian coastal escapes.

Why Is It Called Rabbit Island?

While many assume the name has something to do with actual rabbits, Koh Tonsay gets its nickname from the island’s supposed rabbit-like shape when viewed from above. The name “Tonsay” is derived from the Khmer word for rabbit. Despite the name, don’t expect to find bunnies hopping around—what you will find, however, is a serene, slow-paced environment that feels worlds away from city life.

What Can You Expect on the Island?

Koh Tonsay is the kind of place where time seems to slow down. There are no cars, limited electricity, and internet access is sparse. Instead of resorts or high-rise hotels, the island offers charming bamboo bungalows nestled among coconut trees. Most accommodations are family-run, giving visitors the chance to experience genuine Khmer hospitality.

The island’s main beach—where the boat arrives—is lined with casual beachside eateries serving fresh seafood, tropical fruits, and local favorites. Hammocks sway in the breeze while friendly dogs laze in the sun. It’s the perfect place to unplug, unwind, and reconnect with nature.

Electricity is typically available only in the evenings, usually powered by generators. Bring a flashlight and charge your devices beforehand if needed, although many travelers find joy in going completely offline during their stay.

Activities to Enjoy on Koh Tonsay

While Rabbit Island isn’t packed with structured activities or attractions, that’s part of its charm. The simple pleasures here are what make the experience so memorable. Swimming in the warm, shallow waters is safe and enjoyable year-round. You can snorkel around the rocks at either end of the main beach, though the marine life is modest compared to more developed snorkeling destinations.

Adventurous visitors often explore the small trails that circle the island. These paths lead through dense greenery, offering occasional views of untouched beaches on the far side of the island. Pack water, wear good sandals, and be prepared to share the trail with local goats and chickens.

Massage services are also offered along the beach, often by locals trained in traditional Khmer massage techniques. For a few dollars, you can enjoy a relaxing session just steps from the shoreline.

How to Get to Koh Tonsay

To reach Koh Tonsay, you’ll first need to arrive in Kep. If you’re traveling from Phnom Penh, buses and shared vans make the journey in around 3–4 hours. Kep is also a great detour from Kampot, which is only 30 minutes away by road.

Once in Kep, head to the main pier near the Crab Market, where local boat operators offer transfers to Rabbit Island. Boats typically depart in the morning and return by late afternoon, but overnight stays are common and encouraged. Tickets can often be arranged through your Kep guesthouse or directly at the pier.

Round-trip boat rides typically cost around $10–$20 USD depending on the group size and whether you charter a private boat or share with others.

What to Pack for Your Visit

Pack light and think beach casual. Essentials include sunscreen, bug repellent, swimwear, a flashlight or headlamp, and some cash in small denominations. There are no ATMs on the island, and very few places accept cards. A reusable water bottle and eco-friendly toiletries are also a good idea, as the island’s waste disposal infrastructure is minimal.

Since the island is still relatively undeveloped, it’s best to bring any personal medications, hygiene products, and other essentials with you.

When Is the Best Time to Visit?

The dry season—from November to early May—is the best time to visit Koh Tonsay. The weather is sunny and warm, with calm seas perfect for swimming and beach-lounging. While the monsoon season (June to October) can bring heavy rains, some travelers enjoy the lush landscapes and fewer crowds that come with the off-season.

Because tourism on the island is still low-key, even peak season doesn’t feel overly crowded, making Rabbit Island a peaceful destination no matter when you go.

Can You Stay Overnight?

Absolutely—and it’s highly recommended. While many visitors come for a day trip, spending the night allows you to experience Koh Tonsay’s true magic. As the day-trippers return to the mainland, the island becomes quiet, lit only by the moon, stars, and the occasional lantern from the bungalows.

There are several small guesthouses and bungalow-style accommodations along the beach. Most are simple but comfortable, often featuring a mosquito net, a fan, and a basic bathroom. Prices range from $5 to $20 per night, depending on the season and amenities.

Overnight stays allow for early morning beach walks, stunning sunsets, and a connection with the rhythms of the island that day-trippers often miss.

Is Koh Tonsay Right for You?

If you’re searching for nightlife, luxury resorts, or jam-packed itineraries, Rabbit Island might feel too quiet. But if your idea of a perfect vacation involves sandy toes, hammock naps, and grilled fish eaten with your fingers, Koh Tonsay might just become your favorite stop in Southeast Asia.

It’s ideal for couples, solo travelers, and backpackers who want to disconnect and embrace a slower pace. Families with young children also find it safe and welcoming, though amenities are basic.

Rabbit Island also fits beautifully into broader Cambodia tour packages, especially those combining cultural experiences in Phnom Penh or Siem Reap with coastal relaxation. Travelers working with a Vietnam tour agency can often arrange cross-border packages that include Koh Tonsay, making it a hidden highlight of Vietnam tours that cross into Cambodia.
