Koh Taen & Mudsum: Island Hopping and Snorkeling from Koh Samui
If you’re craving a quick escape to Thailand’s tropical waters, this island-hopping tour from Koh Samui might catch your interest. For about $65, you’ll spend roughly six hours exploring Koh Taen and Koh Madsum, both famed for their scenic beaches and vibrant marine life. The tour includes hotel pickup, snorkeling gear, a Thai lunch, and insurance, making it a convenient way to enjoy some down time in the sun.
We like that the tour is flexible enough to suit those new to snorkeling or beach lovers looking for a relaxing day on the sand. The longtail boat ride adds a splash of authenticity, and the guided commentary helps make the most of each stop. That said, one thing to keep in mind is the cloudy waters reported by some travelers, which can hinder the snorkeling experience. This trip is best suited for those looking for a laid-back day rather than a snorkel fanatic’s dream.
For travelers who enjoy easy, organized excursions that combine sightseeing with some beach time, this tour offers good value. It’s perfect if you’re staying in Koh Samui and want to see a couple of different islands without the fuss of planning everything yourself. However, if your main goal is top-tier snorkeling or underwater visibility, you might want to consider other options.

An Honest Look at the Koh Taen & Mudsum Tour
When we think about island-hopping in Thailand, the scenery, marine life, and local culture come quickly to mind. This tour offers a taste of all three, starting with a pickup from your Koh Samui hotel and a scenic ride on a traditional longtail boat. The boat itself is part of the charm—famous in Thai waters, these vessels evoke a sense of adventure just stepping on board.
Once at Koh Tan, the main activity is snorkeling. You’ll be immersed in warm, clear waters, swimming alongside marine creatures. The tour’s highlight is catching glimpses of marine life, though some travelers have noted that cloudy water conditions can make visibility less than ideal. Robert, in his review, pointed out that “the water was cloudy, making it difficult to see the fish.” Still, the experience of floating in tropical waters with a guide explaining the surroundings is rewarding enough for many.
Koh Tan itself is a beautiful, relatively quiet beach with shallow waters perfect for relaxing or wading. The coral reefs and fish are a good introduction for beginners, but if you’re a serious snorkeler, you might find the underwater visibility less than perfect. Still, the experience is authentic—no artificial reefs or crowded spots here—just nature at its slow, friendly pace.
After about two hours, the tour moves on to Koh Madsum, known for its sandy beaches and peaceful vibe. Here, guests get to enjoy a Thai-style lunch that’s included—spicy, flavorful, and served in a casual setting. Following lunch, you’ll have free time to lie on a reserved sunbed, soak up the sun, or take a dip in the warm waters.
The final part of the day involves returning to Koh Samui, usually around 2:45 pm, where you’ll be dropped off at your hotel. The entire trip offers a well-rounded mix of adventure and relaxation—ideal for travelers wanting a taste of Thailand’s marine environment without a strenuous schedule.
