GLOBAL ONE NEWS (G1) — If  you plan to explore the beauty of Thailand’s Similan islands—let’s say for a night or two—well, we’re giving you a heads up—you can’t for now.

That’s because the Thai government on Oct. 9 banned overnight stays on the island due to environmental issues caused by mass tourism.

According to The Telegraph, starting in January 2019 the island will also limit its daily tourists from 5,000 to 3,325 visitors.

They will also include a ban on boats with a capacity of more than 100 people.

Reportedly, the only exception is those activities operated by licensed deep-sea diving companies.

The famous 11-island Similan archipelago is known for its beaches and colorful coral reefs.

But over the last 10 years, its once-pristine environment reportedly showed rapid degradation due to the harm brought by marine activities like snorkeling, diving, and boating, among others.

The Thai government has not yet clarified how long the restriction will be effective.
