The stretch of the Thames from Twickenham Bridge to Petersham and Ham is one of the prettiest in London. The action is mostly around Richmond Bridge, built in 1777 and London’s oldest surviving crossing, only widened for traffic in 1937. The lovely walk to Petersham can be crowded in nice weather; best to cut across Petersham Meadows and continue to Richmond Park for peace and quiet. There are several companies near Richmond Bridge, including Richmond Boat Hire, that offer skiff hire (adult/child £5/2.50 per hour, £15/7.50 per day).
