This memorial pays tribute to General Ulysses S. Grant and his wife, Julia Dent Grant. The largest tomb in North America, General Grant National Memorial overlooks Riverside Park and the Hudson River. Visit in the warmer months to enjoy the trees and flowers in full bloom, or bundle up in the autumn and winter to view equally beautiful (if chillier) landscapes. Around Halloween, you can take a guided tour of the tomb by candlelight. Or enjoy concerts and walking tours in Riverside Park when weather permits.
