Steven D the Pros and Cons of Lake Atitlan Guatemala
Three Panajachel negatives.
Street dogs, a clear and present danger followed by road conditions and idiotic drivers with an extra helping of NGO Christian soldiers turning Mayan people into beggars while doing the government's job.
Why not help your neighborhood at home first,
Bonus round-Lake Atitlan is an ecological disaster, not swimable nor are the fish edible. Sorry Charlie.
Another plus: inexpensive! Also I enjoyed most of the expats and Mayans I met. And yes, the beauty of the lake and volcano is beyond compare. Definitely, as Marco says, the dogs are a problem., though I never experienced them as a threat.
