Nice trail within reach of Washington DC. The trail is hilly when you start at Chain Bridge and head west and eventually flattens out as it runs by the river. The trail was well marked and ran along side GW Parkway for a short distance and at one point you have to cross a road. The trail starting from about 3 miles west of Chain Bridge looked less used as there were many trees that had fallen across the trail that you had to climb over. At one point, within about a mile from Chain Bridge, you have to cross a stream by hopping stones if you don't want to get your feet wet. Overall an enjoyable hike and not very crowded, especially if you go earlier in the morning.
