The drive

Route 100 is the Brandywine Valley's main road: DE 100, Montchanin Road, runs north from the edge of Wilmington through Montchanin, then crosses into Pennsylvania as PA 100 and ends at Chadds Ford. It's 7.4 miles and about 15 minutes, with mostly gentle curves and a climb of about 300 feet.

The Montchanin Road section is part of the Brandywine Valley National Scenic Byway, and it received scenic designations in 2002 and 2005. Delaware's tourism office describes the valley as rolling hills and grand estates.
