A nice ride from Walople NH south…
Start here: https://maps.app.goo.gl/twZJ5sknTCPJjcLU7
Park at the farm that is closed. Head south on River Road. This will take you back to RT12.

When you get back onto RT12, continue south for about 5000 feet, and make a right onto RT 63. Stop for a Creamy or snack at Stuart & Johns Sugar house. Continue South and there is a second River Road on the right, which goes all the way to West Chesterfield with lots of other smaller roads and places to explore.
