Bang Tao Beach & Surin Beach Map
Maps in Asia are notoriously inaccurate, but this map is actually quite good.
Though they are a bit out of perspective - distances are not accurate in relation to each other
 - the actual placement of resorts and restaurants is generally accurate.
Things change, businesses move, go out of business, open new branches, change their names, etc.
 but generally this map will serve you well.
