Carderock should be a beautiful spot for a hike now that autumn leaves are here! Billy Goat Trails B and C are each about 3 miles, so you can leave after just one for a short hike, or do both for the full monty!

The route: From the westernmost Carderock parking lot, we’ll walk out to the C&O Canal towpath, turn left, and go down to enter Billy Goat Trail section B. After hiking the section upstream, from east to west, we’ll return to our start point via the canal towpath, a total of 3.2 miles. After a short break, we’ll enter Billy Goat Trail section C and hike downstream, from west to east, and return to our start point via the canal towpath, a total of 2.8 miles.

The walk is two loops, one for each section, for a total of 6 miles of smiles. It should take around 2.5 hours at a moderate pace, given the broken ground and time for breaks here and there. The surface is rocky paths along the Billy Goat sections and smooth gravel along the towpath sections.

How to get there: From the I-495 Capital Beltway (either direction), take exit 41 onto Clara Barton Parkway and follow signs for Carderock. On Clara Barton Parkway, take the first exit right at the brown sign marked "Carderock Carderock Div. NavSurfWarCen." After exiting, turn left to cross over Clara Barton Parkway, then continue straight, going around a curve and through a tunnel under the C&O Canal. At the T-junction, turn right and drive to the furthest parking lot to the west. Here's a couple of Google map directions:
