Foothills is a local trail, too short or interesting to be a destination ride, but worth checking out if camping in the area.
There are some views of Port Angeles and the Strait of Juan de Fuca, but otherwise the main attraction is the long riding season, due to low elevation and seasonally dry conditions.
The north and east sides of the Olympic National Park are relatively dry and sheltered from Pacific storms, due to Mount Olympus and surrounding ranges wringing hundreds of inches of moisture year round, resulting in an extended riding season and better trail conditions than one might expect for coastal Washington biking.
Expect a few technical sections, with a hard packed and sometimes rooty trail surface. Extensive use keeps the trail clean and easy to navigate and there are signs posted at major intersections.
The H-1000 parking areas are the usual TH. H-1200 could also be used, which would require some gravel road climbing.
The technically challenging Dry Hill area has about 6mi of trails and is mostly for downhill riders, but worth checking out as well.
White Knuckle was the original DH run and is one-way, like the other DH trails. Plenty of stunts and jumps. Park at Walkabout Rd and ride as much of it as skills allow.
Shown on the Area Map, the 5.5mi (5100' ascent) Heather Park Trail ascends the northern slopes of Mount Angeles, and can be combined with 6mi of Lake Angeles and Switchback trails to form a very challening loop. An ice ax may be needed to hike Lake Angeles during the spring and early summer.
From Kiaski Rd, the 3.4mi (1200' ascent) Heart of the Hills trails is a far more intermediate hike, for those not seeking high elevation wilderness climbing.
The 7mi (4500' ascent) Little River Trail is another day-hike option requiring intermediate skills and stamina, and could even be shuttled from Hurricane Ridge Rd.
Hurricane Ridge is often accessed from Lake Mills, using the Wolf Creek trail and the Elwha-to-Hurricane trail.
From the Whiskey Bend TH, the Elwha River trail passes through lowland forest and valleys, passing Lillian River Camp, Mary's Falls Camp, Canyon Camp, Elkhorn, Hayes River Guard Station, Camp Wilder and Chicago Camp along the way.
The Chicago Camp, river crossing limits access to the Low Divide upper reaches, but that leaves the the lower 23mi of trail to explore. Expect plenty of fellow hikers, as this is a very popular hike.
Elwha to Hurricane Hill Trail and Wolf Creek Trail combine to form a challening 16mi (7000' ascent) CCW loop day hike, which includes 4mi of hiking along the Whiskey Bend Road.
The Long Ridge Trail, Bailey Range Way and Appleton Pass trails can be combined into an epic 31mi (13500' ascent) loop, far beyond a typical day hike.
Needless to say, the Mount Olympus climbing routes should only be attempted by experienced mountaineers who have glacier travel and crevasse rescue skills and gear. Camp areas are located at Caltech Rocks and Snow Dome, with no camping between Glacier Meadows and Blue Glacier.
The National Park includes most of the National Forest, with some wilderness areas at the periphery.
Always carry the 10 Essentials: map, compass, flashlight, knife, matches, nylon cord, extra food and water, and rain gear with warm clothes.
For ONP camping permits, go to the Wilderness Information Center (WIC) in Port Angeles, which is shown on the Area Map. No reservations necessary.
