Palouse to Cascades State Park Trail: Hole in the Ground to Rock Lake

This section of the Palouse to Cascades State Park Trail is generally considered to have a moderate difficulty level. It largely follows an old railroad bed, so the path is relatively well-maintained, but the surface is typically loose and dry gravel. You'll encounter cuts through basalt rock formations and sections with pine trees.

The trail is rich in history, following the former Chicago, Milwaukee, St. Paul & Pacific Railroad route. You'll witness the striking geology of the Channeled Scablands, an "oasis of pine trees," and dramatic basalt formations. Highlights include Rock Lake, the largest natural lake in eastern Washington with sheer basalt cliffs, and the "Hole in the Ground" area where Pine Creek and Rock Creek converge, offering a lush contrast to the arid surroundings. A unique historical point of interest is the presence of derailed boxcars from a 1980 train accident, still visible near Pine Creek Bridge #7.

Yes, the trail includes historic bridges, trestles, and "creepy tunnels" that were once part of the railway. Specifically, Tunnel 43 (756 feet long) is in relatively good condition, while Tunnel 44 may have rockfall. A flashlight or headlamp is highly advisable for navigating these dark passages. Some trestles and bridges might be unimproved or closed due to deterioration, potentially requiring detours.

The best time to hike this trail is typically during the spring and fall when temperatures are milder. Summer can be very hot and dry, while winter conditions can bring snow and ice, making some sections challenging or inaccessible. Always check current trail conditions before you go.

Yes, the Palouse to Cascades State Park Trail is generally dog-friendly. However, dogs must be kept on a leash at all times, and you are responsible for cleaning up after your pet. Be mindful of the gravel terrain, which can be hard on paws, especially in hot weather.

Yes, as this trail is part of a Washington State Park, a Discover Pass is required for vehicle access to trailheads and parking areas. You can purchase a day-use or annual pass online or at various vendors. Always check with Washington State Parks for the most current regulations and any potential closures or specific permits needed for certain activities.

Access to this section can be remote. The primary access point is typically near the "Hole in the Ground" area, often via Hole-in-the-Ground Road. Due to potential detours and ongoing improvement projects, it's recommended to check current trail conditions and access points with Washington State Parks before your visit to confirm the best parking options.

While the trail follows a relatively flat railroad bed, the moderate difficulty level and the length of the full out-and-back (around 17.4 miles) might be challenging for very young children or absolute beginners. However, shorter sections or out-and-back hikes to specific features could be suitable for families with some hiking experience. The gravel surface and dark tunnels are factors to consider.

Beyond standard hiking essentials like water, snacks, and appropriate footwear, a flashlight or headlamp is crucial for navigating the dark tunnels. Given the remote nature of parts of the trail, consider bringing a map, compass or GPS device, and a first-aid kit. Sun protection is also important due to exposed sections.

Be aware of the loose, dry gravel surface, which can be challenging underfoot. The remote nature means limited services, so plan accordingly. Some trestles and bridges may be unimproved or closed, potentially requiring detours. Always check for current trail conditions and potential closures with Washington State Parks before heading out, as improvement projects are ongoing.

This section of the Palouse to Cascades State Park Trail is quite remote, so amenities like cafes, restaurants, or extensive accommodations are not directly at the trailheads. It's best to plan for self-sufficiency and bring all necessary supplies. You might find limited services in small towns further afield, but don't rely on them being immediately accessible.
