Each week, we list opportunities to get outdoors or learn about nature. Click through to the organization hosting each event for more details -- some events require registration or charge a fee.
This week's highlight: Sunday morning, the Sierra Club is leading a 5 mile hike in Montgomery County that will explore the impact of the Inter-County Connector (ICC) on the Paint Branch Watershed. "We will look at the massive current destruction/construction, and discuss the history of the ICC, impacts to local watersheds, as well as the natural beauty and ecological significance of the area. Paint Branch is unique to the area, for supporting the last remaining native brown trout population, and this is a beautiful hike. Meet at 10 am in the parking lot of Valley Mill Park (1600 Randolph Rd., Silver Spring; 0.8 mi. west of US 29, Columbia Pike). Contact leaders for Metro pick-up. Bring bag lunch to continue conversation. Leaders: Kris Unger, email@example.com or 301/980-5621, and Mike Darzi, firstname.lastname@example.org or 301/580-9387."
