The approach to runway 19 at KDCA has good sightseeing, expecially if you are on the port side of the aircraft. But it's probably a stressful approach for pilots. The HAVE to stay over the river to avoid
prohibited areas and there is a 30-degree turn about one mile from touchdown. That's at less than 500-ft altitude most of the time.
