Avoid the tourist crowds and discover the hidden gems of Central Park with the help of a guide. Explore the rolling landscape to find serene areas and ravines in the less-trodden northern section of the park. Encounter one of the most surprising bird sanctuaries in the US, where you can look for robins, tufted woodpeckers or even a rare great horned owl or red-tailed hawk. Walk under Huddlestone Arch to emerge back into the sunlight and climb up to the historic military Bunker to get spectacular views of Harlem. Descend through North Woods to Harlem Meer, surrounded by willow, oak, beech and gingko trees. Skirt the lake and walk up a short flight of stairs to Nutters Battery overlooking north Manhattan. Discover the historic north/south route through the city at McGowan's Pass, and then breathe in the fragrance of roses and magnolia trees at Conservatory Garden.  Sit on a bench under a crabapple tree to discuss your adventure and plan the rest of your day in peace!
