From Hanover follow Route 10 south through West Lebanon to Route 12A, then bear right directly onto scenic River Road, which hugs the shore of the Connecticut River, affording outstanding views of Vermont's countryside (try to ignore the occasional glimpse of busy Interstate 91). The bucolic road also passes several old mansions, including Plainfield's stately Home Hill Inn. The narrow lane is slow going in places, all the better to take in the views. After about 7 miles, River Road puts you back onto the more prosaic Route 12A in Cornish.
