Taxis on Koh Tao to be fair aren't cheap

One of the reasons for this is they do not have meters and all prices for journeys are now fixed and for sure must be amongst the most expensive in the world per km.

What this means when you arrive at Koh Tao is that unless you have also booked in to go diving with Davy Jones Locker and have pre arranged your free pick up from the pier (you can call the dive shop office on 077 456 604 if you're reading this on the ferry on your way here) then you will either need to take the 20 minute walk along the beach road from the pier to the Guesthouse or take a taxi from the pier.  The price to get a taxi from the pier to Sairee is 440 baht, but that price is for the taxi regardless if there is 1 or 8 people on it, so if you are heading here and planning on getting a taxi it's worth asking other travellers if they are also heading to Sairee and sharing the taxi, as otherwise all of the taxi drivers will be happy to take 1 or 2 customers each for the same price.
