Many Richmonders go for bank holiday weekends to the river. I don't mean the James River that bisects the city, but to cottages they maintain or rent along the Rappahannock or Potomac Rivers. In the early 1970s, my family would rent a cottage in Bowler's Wharf (near Sharps), Virginia.
'Pony Pasture' is a nice spot to view or swim in the James river. It is located off Huguenot rd, south of richmond. (I am almost positive there is a brown sign telling you where to go) When tide is low (and if you are adventurous) you can climb on the many smooth rocks that are in the river and get a great view! The greenery there is lush and beautiful as well.
