Olana's 250-acre artist-designed landscape is free and open every day from 8 a.m. (8:30 a.m. in some listings) to sunset, for hiking, walking, cross-country skiing, snowshoeing and paved-surface biking. Guided tours of the historic house and landscape are offered year-round through The Olana Partnership, and reservations are strongly recommended. Self-guided and audio tours are also available. Groups of 10 or more need advance reservations. A second phone listed is (518) 828-0135.
