Boyce Park, Pittsburgh

Named for William D. Boyce, the founder of the American Boy Scouts, who lived nearby, the municipal park features a wave pool and offers a variety of tennis courts, picnic areas and shelters, each of which has a Boy Scout theme. In the winter, people flock to the park for the ski trails: there are slopes for beginners and intermediate levels, cross-country skiing, night skiing, mogul runs and snow boarding. The Four Seasons Ski Lodge rents equipment, sells passes and is a great place to relax after hitting the trails all day.
