Home Page Miller Peninsula State Park (Undeveloped) Downloadable PDF The PDF is a large file with enough detail for zooming in and printing at 300 dpi This park is located on the north Olympic Peninsula between Sequim and Port Townsend. As it is undeveloped, there is little active management by state parks. The trails are user-maintained, primarily by Backcountry Horsemen. Trail names are informal ones used by bicycle and horse users. Since the terrain is mostly flat, it is easy to get lost here, so try to stay oriented on the map. If you have a GPS the latitude and longitude scales at the edge of the downloadable map will help identify where you are (set coordinate display to show fractions of minutes).
