Overview
Tillamook State Forest is a 364,000-acre publicly owned forest managed by the Oregon Department of Forestry, located approximately 40 miles west of Portland in the Northern Oregon Coast Range. The forest is currently open and operating normally. All non-motorized trails remain open year-round, though some may be temporarily closed for timber operations, fire safety, or weather-related hazards. Most developed campgrounds are seasonal, typically open from mid-May through September or October, with some OHV campgrounds (Browns Camp and Jordan Creek) closing October 31st. The Tillamook Forest Center visitor facility is closed during winter months (December-February). The forest receives over 100 inches of annual rainfall, so winter conditions can be wet and muddy. Fire season restrictions were in effect during summer 2025 with a county-wide burn ban starting July 15th, but these are seasonal and lifted post-summer. The forest offers extensive recreation including OHV trails (some with hour restrictions during high fire danger), hiking, biking, horseback riding, fishing, hunting, and dispersed camping. Recent blog posts indicate normal winter operations with no major closures as of late 2025. Check the ODF recreation page or Tillamook State Forest blog for real-time trail and road closure updates before visiting.
