Lincoln Memorial and Washington Monument. Washington DC USA. The 4 of us walked from the Lincoln Memorial to the Capital and then back to our motel. Man did I get a few blisters on my feet, but it was well worth it.
Washington Monument : Though admission into the monument is free, tickets are required and long lines form to get inside every day. A better bet: enjoy the exterior of the monument from the steps of the Lincoln Monument, or from the tidal basin during the National Cherry Blossom Festival in April.
