Small coastal city near the Belize border, located on Lake Bacalar (Lagoon of Seven Colors). We've mapped a nice 9 km out and back run along the main waterfront road -- not a lot of water views, but there are lagoons, a fort, and cool street art!
A lovely run along Chetumal Bay in this waterfront city near the Belize border. A combination path/wide sidewalk follows Boulevard Bahía for ~11 km, with nice palm trees and water views.
