.Rocks Guesthouse was the original hostel on Koh Tao then named Koh Tao Backpackers Hostel back when the local taxi drivers didn't even have the word hostel in their vocabulary and was the very first hostel on Koh Tao.  Since then as with dive school before hostels and pharmacies and then Tattoo parlours there has been an explosion in hostels popping up all over the island, at one point any spare room in a shop or hotel was being stuffed with dorm beds and advertised as a hostel.  .Rocks Guesthouse sticks with the original idea of cheap basic accommodation and is located close to the beach in a surprisingly quiet soi in the middle of Sairee.
