Why go
Coral Island is a small island off Chalong, close enough for a half-day trip.
It's busy with water sports but has calm snorkelling spots.
Good for children and first-time snorkellers.
Banana Beach and Long Beach on Koh Hey have different moods: lively and calmer.
Glass-bottom boats show reef life.
It's a good choice if you have limited time, small children or an elderly family member who doesn't want a long boat ride. You can be on the sand within twenty minutes of leaving Chalong.
The island has two main beaches. Long Beach is the busier one with restaurants and activities; Banana Beach is smaller and calmer, with better snorkelling around the rocks.
The story
Koh Hey was once a quiet fishing island; now it hosts beach clubs.
Its reefs are being protected.
The island's reefs suffered from overuse; protection measures have helped.
Many Phuket families visit on holidays.
Like many islands close to Phuket, Koh Hey went from being a quiet fishing and coconut island to a busy day-trip destination in a single generation. In recent years, operators have introduced mooring buoys and swimming zones to protect what's left of the reef, and some parts of the coral are slowly recovering.
For many Thai families from Bangkok and the south, a day on Coral Island is a classic beach outing, so on public holidays it's full of Thai visitors as well as foreigners.
