Potomac Heritage: Saturday, the Audubon Naturalist Society is hiking from Riverbend Park in Fairfax to Great Falls on the Potomac Heritage Trail ($20-$35). And on Sunday, the Sierra Club is hiking the stretch from Algonkian Regional Park in Loudoun County to Riverbend Park (Free).

Fern Valley: Casey Trees is leading a tree walk on the National Arboretum's Fern Valley Trail on Saturday (Free). It's a beautiful section dedicated to native trees and plants.

Northwest Branch: on Sunday, the Audubon Naturalist Society is back out with a hike on this gem of a trail along the northwest branch of the Anacostia River, in Montgomery County ($20-28).

There are plenty more ideas of things to do on the calendar. We'll see you out there!
