    Join MAREP for a Spring Frog and Wetland Walk!  Spring is a wonderful time to experience the sights and sounds of the wetlands coming back to life after a long, quiet winter.  The tour will be led by Peyton Doub, an ecologist with the Nuclear Regulatory Commission (NRC) with over 30 years of professional experience and a current member of the MAREP Board.

    Pre-Walk Social: We will meet at the historic Old Angler’s Inn (10801 MacArthur Blvd, Potomac, MD 20854) at 5:30 pm for dinner before starting the walk. Please park in the trail lot (https://maps.app.goo.gl/gcP49xFTs3hfcBoG9) directly across the street from the Inn. While there is no cost for the walk, dinner and drinks will be at participants' own expense.   

    In case the lower trailhead parking lot is full, you can park in the upper lot, located just a few steps north of the lower lot. Parking in the trailhead lots is free, and there is no admission fee to enter the C&O Canal Historical Park. 

    Frog Walk: The walk will begin promptly at 7:30pm. Anyone planning to join us for just the walk should plan to meet the group at the trailhead parking lot (https://maps.app.goo.gl/gcP49xFTs3hfcBoG9), directly across the road from Old Angler's Inn. The walk will take place along the Chesapeake & Ohio Canal in Montgomery County, Maryland. We will walk about a mile westward on the flat canal towpath to a place where the normally narrow canal widens out into a small lake. The walk will be slow and easy, and you will not have to get your feet wet.

    ImportantComfortable walking shoes recommended!  Also bring a flashlight or headlamp or you have one. Trail level of difficulty considered Easy (flat/level).  The walk is less than 2 miles total.  Feel free to bring binoculars and a camera!
