It depends where? The Adirondacks are huge.
Some of my favorites:
Tracey Road ( county route 6)
Ensign Pond Road( county route 4)
Route 9N over Tongue Mountain
County Route 7 north of Ticonderoga going to Elizabethtown N.Y.
Schroon River Road out of Warrensburg N.Y.
Around Sacandaga Lake - beautiful road around lake
Anywhere around Lake Placid
If you wan more detailed information, p.m. me. I live in Lake George and woul be happy to give you additional information if you are coming to this part of the Adirondacks.
Fun and safe riding
