About Tup Island (Ko Tap / Koh Tup)
Tup is tiny, and its whole appeal hinges on the tide. When the water drops, a Y-shaped sandbar surfaces and links it to Chicken and Mor islands, so you can literally walk across the sea between them. That is the magic moment.
Show up at high tide and it is honestly just a small beach, pleasant but not remarkable. So this is one where timing makes or breaks the visit.
It is a quick stop on the 4-Islands tour, so plan the trip around low tide if the sandbar walk is what you are after.
Highlights
- Y-shaped sandbar linking three islands at low tide
- Walk across the sea between Tup, Chicken and Mor
- Small, calm beach to relax on
- Quick, easy stop on the 4-Islands tour
Tips
- Everything depends on low tide, check the timing
- At high tide it is just a small beach
- Bundled into the 4-Islands day trip
- National park fee applies, often via the tour
