Park Overview

Miller Peninsula State Park Property represents one of Washington’s largest undeveloped state park holdings, stretching across the Peninsula between Sequim Bay and Discovery Bay in the heart of the Olympic rain shadow. This unique microclimate receives significantly less precipitation than surrounding areas, creating distinctive dry forest conditions rare in Western Washington. The property’s 3,000 acres contain valuable carbon sink forest ecosystems and beach environments that have remained largely untouched by development.

Currently designated as undeveloped park property, Miller Peninsula State Park Property exists in a transitional phase as Washington State Parks conducts extensive planning processes including Environmental Impact Statement preparation and community engagement. The property offers informal hiking and equestrian access through its forest landscape, providing visitors with a sense of the Peninsula’s natural character before any formal development occurs.

Gear Up for Washington Weather

Washington trails are wet more often than not, and the right gear makes the difference between a great day out and a miserable one. We recommend KEEN Targhee IV Waterproof Hiking Boots for solid traction on muddy and rocky terrain, a North Face Alta Vista Rain Jacket because you will need it even on days that start sunny, and the REI Co-op Flash 22 Pack to carry your layers, water, and snacks. All three are available in men's and women's versions. (affiliate links)
