The 150-acre Bloedel Reserve (7571 N.E. Dolphin Dr., 206/842-7631, www.bloedelreserve.org [1], 10 a.m.–4 p.m. Wed.–Sun., $12 adults, $8 seniors, $6 kids, free for children under 5) contains many native plants from Washington, a bog, pond, Japanese garden, moss garden, and spacious lawns, plus the old Bloedel home, now used as a visitors center. The reserve is especially popular in the spring when the rhododendrons are in bloom, but the 15,000 cyclamen plants are also an attraction.
Get here by heading six miles west from Winslow on Highway 305, then following the signs another mile to the entrance. Reservations are necessary because they only 200 people per day are admitted.
