Is Koh Tao Safe for Tourists in 2026?

Rental shops at Koh Tao document pre-existing damage poorly or not at all, then claim tourists caused scratches or dents upon return. Charges of 3,000–15,000 THB are demanded to cover 'repairs' that are never actually made. Some shops retain the tourist's passport as deposit collateral, giving them significant leverage. The island's winding hilly roads make minor scratches genuinely common.

How to avoid: Photograph every angle of the scooter before riding, including existing scratches and dents, and send photos to yourself with a timestamp. Never surrender your passport as a deposit — offer a cash deposit instead. Inspect the bike with the rental agent present and have damage noted in writing.

Where: Scooter rental shops along Mae Haad pier road, Sairee Beach main road, and near Chalok Ban Kao — concentrated around the ferry arrival area where tourists rent immediately on arrival

Fraudulent websites mimicking legitimate Koh Tao dive schools accept online payments for PADI or SSI courses then disappear or deny the booking on arrival. These clone sites appear in search results and on social media ads, often using stolen photos and reviews from real operators. Victims arrive at the island having paid hundreds of dollars with no recourse. The real school has no record of the booking and the scam site is unreachable.

How to avoid: Book directly through the official website of established schools like Big Blue Diving, Crystal Dive, or Ban's Diving Resort — verify the domain carefully. Pay via credit card for chargeback protection. Confirm your booking via email with a human response before departure.

Drinks spiked with sedatives are reported in beach bars around Sairee Beach. Victims are robbed while unconscious. Some reports involve bucket cocktails purchased from beach vendors.

How to avoid: Never leave a drink unattended. Avoid shared buckets with strangers. Travel in groups at night and look out for friends who seem suddenly very intoxicated.

Where: Beach bars along Sairee Beach (the main tourist strip on the west coast), and at Freedom Beach and Tanote Bay bars on the east coast of Koh Tao, Surat Thani province, Thailand

Koh Tao has a well-documented pattern where dealers sell drugs to tourists then tip off corrupt police officers who arrive shortly after to arrest the buyer. The 'fine' to avoid formal arrest typically runs 20,000–50,000 THB. The island's remote location and limited legal recourse make it difficult for victims to challenge demands. Some operations involve the dealer and officer working as a coordinated team.

How to avoid: Refuse all unsolicited drug offers — even seemingly casual ones from friendly strangers. Be aware that acceptance can trigger an immediate police encounter. If confronted by police, request to contact your embassy before paying anything.
