You have one hike you can do in Shenandoah National Park. Any distance. What is it and why?
We did a few short hikes in a park. Favorite was the short Bearfence Rock Scramble: only one mile long with a 311 foot elevation gain. It required climbing over rocks and hoisting yourself up and over boulders so there was a fun factor. Brief description of the other 3 hikes we did are here: https://www.tripoverlife.com/shenandoah-national-park/
Lewis Spring Falls Trail is a nice trail that will accommodate hikers of varied levels. It’s a 2.8 mile loop and considered “moderate.” Our dog did fine on this one. Gorgeous views of the falls, nice open views of the valley. It’s a little rocky in some areas but not a ton of elevation gain (816 feet). It’s also close to Big Meadows Camground, so definitely check this trail out if you’re staying there!
