The most striking feature of this town is that it has practically no roads — everything is reached by thin foot paths through trees and between buildings. Handmade signs direct you to the most common destinations at any intersection.
The homemade paths have a very intimate feel to them. They are shaped by the plants and flowers that create almost fences that guide you in the correct path.
There are minimal streetlights and not many signs so I would recommend paying attention to where you are going and don't be scared to ask the locals if you are lost! Many of the roads are narrow and curvy so I suggest your full attention to where you are going!
Most of the modern infrastructure resides in San Pedro where streets are paved and there are more signs dedicated to the comprehension of lost tourists.
Majority of the travel within the area around Lake Atitlan is by boat. There are fifteen 'major' pueblos or small towns surrounding the lake, San Marcos included.
