Arrive Early to Check Gear
Meet at Saladan Pier 30+ minutes early to confirm your snorkel fit and life jacket; guides do quick briefings before departure.
Bring Reef‑Safe Sunscreen
Sunscreen is mandatory for skin protection and reef health—apply before boarding to avoid oily runoff in the water.
Be Tide‑Aware for the Cave Swim
Access to the Emerald (Morakot) Cave depends on tide and sea conditions; if currents are strong the operator may reroute to Koh Ngai.
Protect Your Valuables
Stash phones and wallets in a dry bag or leave them on the boat—waves and sand are a fast way to lose electronics.
Reef‑safe sunscreen
Protects your skin and the coral—apply before boarding and reapply after swims.
Water shoes
Useful for rocky boat landings and scrambling onto small beaches and reef flats.
Dry bag or waterproof phone case
Keeps valuables and electronics dry during transfers and while snorkeling.
Light travel towel & swimwear
Quick‑dry towel and swimwear make beach breaks and the return trip comfortable.
