    Pak Bia: Krabi's Most Dramatic Cave Island

    Why Pak Bia?

    Image

    Dramatic Cave Systems

    The caves here are extraordinary. Sea caves with high ceilings, stalactites hanging like natural sculptures, and geological formations that tell stories of deep time.

    Exploring these caves adds an element of discovery and adventure.

    Remote, Less-Visited

    Pak Bia is far less visited than the famous islands. This isolation means fewer tourists and more authentic experience.

    Excellent Snorkeling

    Despite being remote, the snorkeling is exceptional. Healthy reefs host diverse marine life.

    Geological Interest

    For anyone interested in geology, Pak Bia is fascinating. The cave formations, rock stratification, and visible geological processes provide insight into earth science.

    What Our Guests Say

    TripAdvisor★★★★★

    We’ve visited the Phi Phi Islands on a previous trip to Phuket, but I can confidently say that our experience with Simba Sea Tours was on another level! Firstly, the boat was noticeably more modern, exceptionally clean and comfortable compared with our previous experience. The crew were incredibly professional, genuinely friendly and attentive throughout the entire day. There was also an abundance of food, snacks and refreshments available, so we were certainly never left hungry! One thing that really stood out was the tour guides’ willingness to actually get into the water with us, helping us explore and pointing out things we otherwise might have missed. It’s these little touches that make such a big difference. A couple of recommendations: I highly recommend organising a private transfer to the departure point. Also, don’t be put off by the early start! Getting out on the water before the crowds arrive is fantastic, and the sea is generally much smoother in the early morning, making for a far more enjoyable boat ride. You’ll probably notice that Simba Sea Tours is considerably more expensive than many of the other Phi Phi Island tours available in Phuket. However, having experienced both, I can confidently say you absolutely get what you pay for. The quality of the boat, professionalism of the crew, attention to detail and overall experience make the extra cost completely worthwhile. If you’re considering a Phi Phi Islands tour, I wouldn’t hesitate to recommend Simba Sea Tours. Five stars and worth every cent!

    This trip was great. Transport actually came early and we were on the boat by 6am. Sara gave us a quick brief and we watched the sunrise on the way to Maya beach. The beach was pretty empty and the breakfast was good with plenty of food. We had a lot of time to swim and snorkel at the stops and they pointed out cool fish and baby sharks to see in the water. There were only 7 of us so plenty of room on the boat although the seating was enough that it wouldn’t feel too crowded even when full. Everything was well organized. Sara and crew were great definitely recommend this island boat tour it was my favorite tour of my trip!

    Do not skip this tour if your are in phuket. 100% worth it. Ask for Momo as your tour guide. She is amaizing and made the trip x10 times better. Maya beach was closed due to the date but the alternative is really good as well. All spots were on point. The food at the end of the tour was amaizing. Best pad thai we had since we arrived to thailand
