In Central New York State, the FLCC and OCC publish maps of their club rides. The FLCC maps (updated May 2016) are old chestnuts. The OCC maps are useful too. The OCC has a huge number of rides, many of them well into the Finger Lakes territory. With any such maps, though, if you’re not familiar at all with the region, please get a good backup map and note cell phone coverage is spotty still in central New York.

Onondage Cycling Club map page — it’s a huge library of great routes.
Cornell University — maps of the campus and a bit of surrounding Ithaca.
