Check out the Pawpaw Trail at Blockhouse Point Conservation Park. Park on River Road near the intersection with Petit Way. Follow the Blockhouse Trail for 1.5 miles then take the short Pawpaw trail a quarter mile to a rock outcropping with a spectacular view of the Potomac River and the C & O Canal trail. When the trees are not fully leafed out you can see all the way to Dickerson. There's a perfect rock outcropping to sit on and enjoy the view.
