The boat slips away from Phuket and the horizon opens: sunlight glances off low clouds, gulls pick at the wake and the island grows like a green pebble ahead. Khai Island — often called Koh Khai Nok by locals — is compact: white sand fringes a flat interior and cats roam the shade, curious and unhurried. The water dares you to step in; shallow reefs sit within easy swim from shore and currents nudge you out toward small bommies.

History
Khai's role was traditionally a small fishing stop and temporary shelter; its tourism rise is recent, shaped by Phuket’s growth as a travel hub.
Conservation
Stick to marked swim areas, avoid stepping on reefs and use reef‑safe sunscreen; small islands are sensitive to litter and overuse.

Bring reef‑safe sunscreen
Protect coral and skin—use a mineral sunscreen and reapply often after swimming.
Mind the cats
Admire but don’t feed island cats; human food can upset their digestion and attract pests.
Wear water shoes
Beaches have shell fragments and rocky outcrops; shoes protect feet while entering and exiting the water.
Stay hydrated and shade up
Short trips under tropical sun dehydrate fast—carry water and a hat between swims.
Reef‑safe sunscreen
Protects coral and prevents sunburn during open‑water snorkeling and beach time.
