Tacoma to Cannon Beach Road Trip: Complete Guide

This 160-mile route from Tacoma, WA to Cannon Beach, OR takes you along Interstate 5 south to US Route 26 west, crossing the Columbia River and the Oregon Coast Range. The drive typically takes 3 to 3.5 hours without stops, but the real value lies in the detours. The route passes near the 1980 eruption zone of Mount St. Helens, a geological event that reshaped the landscape and continues to influence local soil fertility.

Key highways: I-5 south from Tacoma to exit 36 for US-26 west near Portland, then US-26 all the way to Cannon Beach. Estimated driving time: 3 hours 15 minutes. Local milestone: milepost 0 on US-26 at the Oregon coast.

Road quality is excellent on I-5 and good on US-26, but watch for fog near the coast and logging trucks on the winding sections. Cell service drops significantly between mileposts 30 and 45 on US-26.

Family stop: The Oregon Zoo in Portland (exit 35 off I-5) is a great midday break. Pet-friendly: Dogs on leash are allowed on Cannon Beach, but not on the sand near Haystack Rock during nesting season (March-September).

• Rest zones: Plankton Rest Area (US-26 milepost 20) has picnic tables.
• Fatigue management: Take a 15-minute break every 2 hours. Ideal stop: St. John's Bridge viewpoint in Portland.
• Hidden off-route: The unusual 'Octopus Tree' at Cape Meares, a 10-mile detour near Tillamook.

The drive transitions from Puget Sound lowlands to the Columbia River estuary. Near the coast, US-26 winds through Sitka spruce forests with moss-draped branches. Notable stops: Mount St. Helens National Volcanic Monument (detour from I-5 exit 49) and the Tillamook State Forest.

Local commerce: In Cannon Beach, browse local galleries selling driftwood art and Haystack Rock photographs. The town's main street is lined with seafood shacks and chowder houses.

1. Stop at the Astoria-Megler Bridge viewpoint on US-101
