The route is mostly trail with some old road and a little bit of the Centennial Trail. There are great views from the top of Pine Bluff, a scenic section that follows along the Spokane River, and a rocky section that will lead visitors through geologic basalt formations. The trail surface becomes rocky in sections especially as visitors travel through the basalt formations.

Need to Know

You'll need a Riverside State Park Discover Pass to park at the trailhead. They can be purchased at the State Park or at various locations in Spokane or online. More information can be found here: discoverpass.wa.gov/


This route starts with a short incline on Pine Bluff Road. Be careful here and watch out for cars. Look for Trail 25 (North) on your right, and start heading this way.

You'll remain on Trail 25 (North) as it continues out to a terrace between the dry Deep Creek below and Pine Bluff above. Be sure to look up at the basalt cliffs above you. At the first junction you turn left and head uphill to the top of the Bluff. There are benches there to catch your breath after the climb and views to enjoy.

Stay on the trail that goes past the benches close to the Bluff - it forks soon. Take the left junction to stay on Trail 25 (North) which heads inward from the bluff. Follow the trail across the bluff, and as it starts to go downhill watch for the next junction is to the right- Trail 401. Take Trail 401, but you'll only be on this one for a short while.

The next junction that you'll reach takes you back to Trail 25 (North). Turn right and follow Trail 25 for just a little bit before coming to Trail 400. You'll take a left here, which will take you to the Centennial Trail.

When you reach the intersection with the Centennial Trail, take a right to reach the picnic area by the Deep Creek Bridge. This is a beautiful spot to enjoy the river. If you have time explore Deep Creek Canyon, you won't be disappointed.

When you've finished exploring, keep a look out for a rock fall where you'll see a sign and a trail going up into the rocks. Take this trail up into the rocks above the canyon. It is a lava/basalt field and great for photographs. Not a lot of vegetation as of yet. As you go up make sure you look back at the bridge below and the rock formations across the creek.

At the top of this rocky route, turn left on Trail 25 (North) as it goes down into Deep Creek. Head up Deep Creek watching for the continuation on the left where Trail 25 (North) goes up to the other side. There you'll find an old road.

To get another view of Deep Creek formations find your way out to the road, watching for the overlook to the left. Then retrace your steps back from the overlook, and continue on the road.

Eventually, you'll come to a white gate where you'll pass through. Once you've reached a parking lot, look for a trail that leads back to the creek on the right. While there are no signs, it will take you down and then back up to the starting point. There are 2 choices of trails - both lead up to the parking lot.

Flora & Fauna

Fall colors and spring wildflowers.

Fairly easy hike. Some switchbacks and steep inclines at parts but easy coming from the north. However, you have to cross deep creek. 5.7mi

River is washed out so be careful...you have to go around instead of being able to do the complete loop.
