Day trip to Similan Islands

All you need to know about a day trip to the Similan Islands.

The Similan Islands form an archipelago of nine islands, as the name “Similan” suggests, as it translates to ‘nine’. These islands are a protected area, declared a National Park, with a daily tourist limit to help preserve the ecosystem. You can read more about the park here.

Although I had heard the opposite, I didn’t find the islands crowded. In fact, it was quite peaceful, and we had plenty of space on the beach without being surrounded by crowds. However, depending on the day or season, everyone’s experience may be different.

There are only a few operators running these tours, and tickets can be bought at travel agencies, dive centres in Khao Lak/Phuket, or even at your hotel’s reception. Our trip was organised by WOW Andaman, and everything went smoothly.

The package typically includes:

  • transport from hotel to Khao Lak pier and back
  • pre-departure breakfast at the pier
  • snorkelling equipment
  • snacks, fruit and water throughout the day
  • lunch on one of the islands
  • light dinner on arrival at the pier

The WOW Andaman staff gave us a briefing on our day before we boarded the boat. They reinforced good wildlife interaction practices, which is always a good reminder for some people.

The trip to the first island takes about an hour and a half, and believe me, the boat is REALLY fast as it has multiple engines! Fortunately, no one in our group got seasick, although I could see it happening. The crew were always handing out sweets which prevents sickness, and I think that really helped.

At one point the captain turned off the engines so we could watch a family of whales pass by – what a privilege!

My only criticism of the trip, if I have to have one, was the waiting time. We were picked up from our hotel in Khao Lak very early in the morning, and there was a bit of a wait at the Khao Lak pier before the boat left. This is because three or four boats leave at the same time, and as some people come from Phuket, which is further away, and it takes them longer to get to the pier. Still, it was well worth getting up at 6 am!

As this is a protected area, this tour is only available between 15 October and 15 May, when the National Park reopens after the conservation period.

Final thoughts on the Similan Islands

I loved the day! While the snorkelling itself wasn’t that great, the beaches are absolutely stunning. The turquoise water is crystal clear and even warm! There’s a lookout point on one of the islands that you can climb, but we decided to stay and enjoy the gorgeous beach.

Alternative to the Similan Islands: the Surin Islands

Another popular trip that leaves from the same pier is the day trip to the Surin Islands. Although the snorkelling is considered better here, the longer travel time (two hours each way) can be a challenge, especially with children. Still, it might be worth considering.
