Cycling is huge in Belize, lots of teams. Highways are our velodromes. Just had friends ride from PG-Dangriga, Dangriga to San Ignacio, San Ignacio to Belize City and Belize City to Corozal, a segment per day. Too grueling for leisure riding, but one of these segments should suffice. The most scenic would be the ride from Dangriga to Belmopan, which also has the largest hills.
