Full description
Explore the beauty around the Phi Phi Islands on a 6-hour longtail boat tour. Watch the sunset over the Phi Phi archipelago and enjoy some included snacks, then take a dip with bioluminescent plankton once the sun has gone down.

Make your way to the meeting point in front of McDonald's in Tonsai Bay at 1:30 PM. Once you have boarded your boat, depart for Monkey Beach, one of Koh Phi Phi's most interesting beaches inhabited only by monkeys. Encounter the macaques on the island, which are also known as crab-eating macaques as they are often seen foraging for crabs.

Next, sail to discover the mysteries of the Viking Cave, famous for the seemingly prehistoric painting of a Viking boat on its wall. The cave was once used for the extraction of birds' nests, prized ingredients in Chinese culture for making medicinal soups believed to help with longevity.

Continue your tour to Pi Leh Lagoon, and marvel at the azure/turquoise waters in this beautiful enclosed lagoon encircled by towering limestone cliffs. See certain spots glow from beneath the water, and take advantage of this fantastic photo opportunity.

After Pi Leh Lagoon, head to Loh Samah Bay to snorkel with diverse marine life on a coral reef. Admire this wonderful paradise, which provides an alternative to the world-famous Maya Bay from the film “The Beach” due to its proximity. Maya Bay is closed for another 2 years to allow recovery from over-tourism but is separated from Loh Samah Bay by only one limestone mountain.

Finally, enjoy a spectacular sunset with views of the Phi Phi archipelago before swimming with bioluminescent plankton at night. Delight in the glow of the plankton as they are touched in the water, making it look like you are swimming with stars in the night sky. The tour concludes with a transfer back to the port at around 7:30 PM.

The activity is great, in a typical long tail it's really good. Two stops to take the time to swim and snorkel, lots of beautiful fish ... By cons, we were really not alone, which distorts a little everything else and the guide was really bad, he just announced each place and the duration we had on site! No comments on the rest and hardly goodbye ...! Others seemed more sympathetic, it really depends on who you come across ...

The tour was ok! Price-performance ratio is also okay, but I went on many other better tours. The organization was not as good as on other tours and the driver of the longtail boat could not speak English as stated. You didn't know exactly where you were and you didn't get any information. Well, you can do it - you don't have to.

I actually took the island hopping trip twice! Was super happy I could book this tour last minute since I was not able to communicate with the long tail boat guys at the pier. The first time taking the tour the weather wasn’t so great so I decided to take it a second time. Very glad I did because the weather was amazing the second time round and the water super clear and snorkeling spots were stunning. Being able to swim in glowing plankton was also a highlight of my entire trip. The boatman was friendly and he helped get up on the boat and down the entire trip. Didn’t feel awkward at all as a solo traveller.
