We went here on New Year's Day this year! There are easy-moderate hikes anywhere from 3-7 miles, with great overlook views! You'll be able to see this mountain from the wedding ceremony site! There's also a winery, Sugarloaf Mountain Vineyard, at the bottom of the mountain.
This is a great American restaurant in downtown Leesburg. They also have fun cocktails!
Lot's to do here, from hiking (with great overlook views over the river), Harpers Ferry National Historical Park, tubing down the river, ice cream, restaurants, and local shops.
