Lake Wintergreen is a great place to get outside for a good run, and it is just a quick 10-15 minute drive from downtown New Haven. There is ample parking available at the park, and many families go for hikes with kids and pets at all times of the day. There is a trail circling the lake, it can take 15-30 minutes to cover the entire loop, depending on pace. There are so many beautiful views of the lake, dam, and surrounding fields. Classic New England landscape.
