Only one paved road, Wash. State Rte. 20, goes through the park complex. There are a few unpaved side trips, though. The Cascade River Road, which leaves Wash. 20 at Marblemount, enters the national park proper as an unpaved road. The gravel Stehekin Valley Road above High Bridge also enters the national park. This road does not connect with the outside world, however; rather, the park concessionaire provides a shuttle service along this road from mid-May to mid-October.
From Seattle on the west side, take the Wash. State Rte. 20 exit 230 off I-5 and head east, toward Rockport and Marblemount, into the park. From Spokane, the major metropolitan area on the east side, it's U.S. 2 West, linking up with U.S. 97 North, to Wash. State Rte. 153 and, finally, Wash. State Rte. 20. And remember, in the winter, these roads may close at any time from late October to early May. Be sure to call ahead.
The Nearest Airport -- Seattle-Tacoma International Airport (tel. 206/787-5388; www.portseattle.org/seatac) is 15 miles south of Seattle on I-5. The airport is served by practically all major airlines and car-rental companies.
