People flock to seaside beaches, mountain trails, and lake boat ramps in summer. In the cities, festivals showcase music, theater, and crafts. Fall brings leaf-peepers, especially to the White Mountains and along the Kancamagus Highway (Route 112). Skiers take to the slopes in winter, when Christmas lights and carnivals brighten the long, dark nights. Spring's unpredictable weather -- along with April's mud and late May's black flies -- tends to deter visitors. Still, the season has its joys, not the least of which is the appearance of the state flower, the purple lilac, from mid-May to early June.
