Coral Island Day Trip From Phuket: What to Expect

By Phuket Thailand Travel · Local Phuket travel experts · Published October 11, 2026

Fifteen minutes from Chalong, and the water is already a different colour.

A Coral Island day trip from Phuket is the island’s easiest island escape — Koh Hey sits just 15 to 20 minutes by speedboat from Chalong Pier, making it ideal for half-day trips, families with young children and anyone short on time. The island has clear, shallow water for snorkelling, two main beaches including Banana Beach, and a full range of watersports. It’s often combined with Racha Island or a sunset cruise on a full-day programme.

Why Coral Island is so popular

The closest proper island

Coral Island, known locally as Koh Hey, sits just off Phuket’s southern coast and is reached in 15 to 20 minutes by speedboat from Chalong Pier. That proximity is the whole appeal: you spend almost no time in transit, the crossing is short enough that seasickness is rarely an issue, and a half day is genuinely enough to enjoy it. For families with young children or visitors with one spare morning, it’s the most practical island trip from Phuket.

Clear, shallow water

The water around Coral Island is noticeably clearer than the main Phuket beaches, and shallow enough near shore for confident snorkelling without a boat. That combination makes it a good introduction to snorkelling for children and first-timers.

The beaches

Banana Beach and Long Beach

• Banana Beach — the smaller, quieter of the two, popular for snorkelling
• Long Beach — the main beach, with most facilities and watersports
• Facilities — loungers, restaurants and toilets at the main beach
• Water — shallow and generally calm, good for children

Most tours base themselves at Long Beach, with Banana Beach either included or reachable separately.

Half day or full day?

How to structure it

Because the crossing is so short, Coral Island works beautifully as a half-day trip — out in the morning, back for lunch, with the afternoon free. For a full day, most operators pair it with Racha Island, which has clearer water for snorkelling, or extend into a sunset cruise. A private speedboat or yacht charter can combine both at your own pace. See speedboat charters and yacht charters.

Costs and what to budget

Rough expectations

Shared speedboat trips to Coral Island are among the more affordable island options from Phuket, generally cheaper than a Phi Phi day trip because of the shorter distance. Budget separately for optional watersports, which are paid on the beach, and bring some cash as not every vendor takes cards. Private charters are priced per boat and start from around 15,000 THB for a half day. See our day tour cost guide.

Coral Island vs the alternatives

How it compares

• vs Phi Phi — far closer and calmer, but less dramatic scenery
• vs Racha — closer, but Racha has clearer water for snorkelling
• vs Khai Island — similar shallow-water appeal, both family-friendly
• vs Phang Nga — Coral is about swimming; Phang Nga is about scenery

Best time to go

Season and time of day

November to April brings the clearest water and calmest conditions. Because Coral Island is close to shore and partly sheltered, it also holds up better than open-sea trips during the green season, making it a reliable choice when Phi Phi or Similan trips are weather-affected. Mornings are quieter and the water is usually clearest before the day’s boat traffic builds.

Practical tips

Before you go

1. Take the morning departure for clearer water and fewer people
2. Bring reef-safe sunscreen and a hat — shade is limited
3. Carry cash for optional watersports and drinks
4. Confirm whether lunch and snorkelling gear are included
5. Consider pairing with Racha Island if you want a full day
