Out among the hardwood tree stands and small lakes and ponds of Lebanon Hills, the wintertime trails are nicely groomed and, better yet, never crowded. Best of all is the sense of escape from the cities; houses and paved roads are rarely visible from anywhere in the park. Judging by its proximity to the airport, you'd think passing planes might trouble the tranquility, but we can't think of a single instance of jet noise messing with our ski-induced trance. There are trails for both the novice and the workout-minded expert, and while most parks close at sunset, Lebanon Hills is open until 10:00 p.m., offering the sweet option of a moonlight ski after a long day's work.
