This tour promises a quick boat ride from Phuket’s coast to three small, stunning islands, each offering its own flavor of tropical bliss.
While it’s a well-loved option with over a thousand reviews averaging 4.2 out of 5, it’s worth digging into what makes it a solid choice — and where it might fall short.

The fact that it offers both half-day and full-day options means you can tailor your experience to how much adventure or relaxation you want. Plus, the inclusion of snorkeling gear, snacks, and insurance underlines the focus on value, making this a practical pick for budget-conscious travelers.

The Itinerary in Detail

Starting/Meeting Point:
Most travelers will meet at Asia Marina Pier, with check-in starting around 8:45-9:00 AM for the morning and full-day options, or at 1:00 PM for the afternoon tour. The staff, donning bright orange shirts, are easy to spot on the pier. It’s important not to arrive too early or late, as late arrivals after 9:15 AM (morning) or 1:15 PM (afternoon) won’t be accommodated.
The Journey Begins:
Once aboard the speedboat, you’ll quickly realize that this is a lively ride—fast and bumpy, but part of the adventure. The boat, equipped with 2-3 engines, can hold 30-45 passengers, so it’s sizable but not crowded, and the ride typically lasts about 15-20 minutes to the first island.
Khai Nai (Cat Island):
This is the star attraction for many. Just about 15 minutes from Phuket, it’s known affectionately as Cat Island for the many friendly cats lounging on the soft sands. The shallow waters make it ideal for families. You’ll have around an hour for relaxing, swimming, and snorkeling here in the company of the island’s feline residents. Several reviews mention the charm of spotting the cats and the beauty of the beach, although some note that the shore is crowded with umbrellas and beds that might not be to everyone’s taste. As one traveler put it, “If you’re allergic, you can still go coz they don’t come to you,” highlighting the calm nature of the cats.
Khai Nui:
A tiny, uninhabited island with no beaches but rich marine life. Here, the focus is on snorkeling among coral reefs and tropical fish. The stop lasts about 30-45 minutes, and you’ll be encouraged to jump into the water directly from the boat. This is a highlight for snorkelers who want to see colorful fish and coral close-up. Multiple reviews praise the underwater experience, with one noting “plenty of fish and beautiful coral,” although some mention the water can be murky if the sea is choppy.
Khai Nok (Nok Island):
The last stop is a gorgeous, quiet beach with minimal development. Sunbathing or swimming are top activities here, and you’ll have about an hour to enjoy the natural beauty. Snorkelers and relaxers alike love this spot for its peaceful vibes. Guests appreciate the freedom to choose their activity, whether it’s a quick dip or lounging on the sand. One reviewer calls it “the perfect peaceful escape,” especially compared to busier mainland beaches.
Return & Free Time:
After the island visits, the boat heads back to Asia Marina, where some guests enjoy a short window of free time to explore or grab a beverage. The entire trip wraps up around 1 PM if you chose the morning tour or by 5:30 PM for the full-day experience.
