Phang Nga Marine Parks Closing: What It Means for Your Phuket Trip

Planning a Phuket Getaway? Here’s What You Need to Know About the Marine Parks Closure

If you’ve been dreaming about snorkeling in crystal-clear waters or exploring Thailand’s most iconic islands, we’ve got some important news that might affect your travel timeline. Two of Phang Nga’s crown jewels—the Surin Islands National Park and the Similan Islands National Park—will be closing their doors to visitors for five months, from May 15 through October 15, 2026.

Before you panic, let’s break down what this closure really means for your Phuket adventure and how you can plan accordingly.

Why Are These Marine Parks Closing?

The Department of National Parks, Wildlife and Plant Conservation made this decision to protect these precious ecosystems during their most vulnerable season. The May-to-October period is monsoon season in Thailand, bringing rough seas, strong currents, and challenging weather conditions. Beyond safety concerns, this closure allows the marine environment to recover and regenerate—crucial for protecting coral reefs, seagrass beds, and the incredible marine life that makes these islands world-famous.

It’s actually good news for conservation-minded travelers who care about preserving Thailand’s natural beauty for future generations.

How Does This Affect Your Phuket Travel Plans?

If you’re thinking about visiting during the traditional peak season (November through April), you’re in luck! The closure only impacts the off-season months, which means the best time to visit these islands remains perfectly accessible.

However, if you’re a budget traveler or prefer smaller crowds, this closure eliminates the possibility of visiting during the shoulder months of May, June, or early October when prices typically drop.

Alternative Activities While the Parks Are Closed

Don’t worry—Phuket has plenty to offer even if the Surin and Similan Islands are temporarily off-limits. Consider exploring:

Phang Nga Bay’s Limestone Wonders – Kayak through dramatic karst formations and hidden lagoons. The scenery rivals any island destination, and you’ll likely have a more intimate experience than the crowded main islands offer.

Nearby Island Alternatives – Islands like Koh Panak, Koh Lanta, and Koh Samui remain accessible year-round and offer equally stunning underwater experiences.

Land-Based Adventures – Trek through jungle canopies, visit elephant sanctuaries, or explore Phuket’s vibrant night markets and cultural temples.

Whatever you choose, GoGo Phuket’s comprehensive tours can help you craft the perfect itinerary that works around the marine parks closure.

Smart Travel Tips for 2026 and Beyond

Book strategically: Plan your island-hopping adventures between November and mid-May to experience the Surin and Similan Islands at their absolute best—calm seas, excellent visibility, and perfect weather.

Consider shoulder seasons smartly: Late April and early May offer great deals and fewer tourists, though you’ll miss these specific marine parks.

Flexibility is your friend: If you’re flexible with your dates, you can take advantage of lower prices during off-peak months and explore alternative attractions that don’t have seasonal closures.

The Bigger Picture

While this marine parks closure might seem inconvenient, it’s actually a positive sign. Thailand’s commitment to environmental protection means that when you do visit these islands, you’re experiencing them at their healthiest and most vibrant. The five-month rest period helps ensure that coral bleaching is minimized, fish populations remain robust, and the underwater landscape you came to see remains spectacular.
