Speedboat to Phi Phi
Private Speedboat Transfer is the next most popular way of getting to Phi Phi. Basically, it’s a private charter of a speedboat, so departure and drop-off points are a little more flexible and you can go right up to the front of your chosen resort, which can save a lot of time.
For most of the year, the ride is flat, but it’s advisable to avoid speedboats in low season (from September to November) as things can get a little bumpy. Obviously, speedboats are more expensive than the ferry, but they can represent excellent value for larger groups as the cost of the boat hire is divided.
The cost of 4 Seater Speedboat would be around 11,000THB till Phi Phi Island.
