If you haven’t already visited Croton Gorge Park, you should. Not only is it visually stunning (with a soundtrack of rushing water to boot) this is the perfect place to spend an afternoon. Visit on a weekday and avoid paying the $10 parking fee ($5 if you have a Parks Pass) which is collected May-September. Managed by the Westchester County Parks Dept., the entrance booth is staffed Fridays-Sundays, and when the park fills up, they close access. If you are lucky enough to make it in and across the bridge, there is a vast lawn with spots to picnic and a playground for the kiddies. Take the trail up to the top of the dam, worth the hike for the spectacular views. If you are feeling particularly adventurous, bring your bike and hook up to the Old Croton Aqueduct Trail, a 26+ mile park which run from here all the way to Van Cortlandt Park at the Bronx County/City of Yonkers border.
