It is strongly recommended that you use the directions below. They are
exceptionally accurate. Relying on a navigational system can lead you to
OSP on roads that are much less desirable than the ones outlined in our
Remember: sunset at this time of year is around 8:00 PM. Please try to arrive
before dark. But if you are unable to do so, be cautious of deer or other
animals on the roads, particularly around dusk or dawn. Anticipate an hour
drive from Prineville to the site. Roads are paved except for the last four
miles, which are gravel and in good shape.
Those arriving after 8pm should plan on spending their first night parked
at the entry Late Night Arrival Area.
The road into the main area will be blocked and you will be asked to camp
in the late night arrival area at the entry near the registration tent. The
road will reopen at 10am in the morning.
We have had some trouble in the past with local hunters removing our signs,
so if you follow the mileages listed, you will find OSP without any problem.
Please check the Oregon Department of Transportation web page
tripcheck for up-to-date road
information. The link for Incident Maps will take you to a 9 section grid. The Indian
Trail Spring site is in Central Oregon. The site is east of Prineville along Highway 26.
Contact us, if you need additional directions. A good idea
is to pick up either a Pittmon’s map for Crook County, or a National Forest Service
map of the Ochoco's for detailed information about the area.

From western Oregon, western Washington & California:
Travel east out of Prineville on State Highway #26.
Zero your trip meter at the US Forest Service Headquarters at the east end of
town. Stay on Hwy 26 for approximately 14 miles (A), then turn right onto the
Ochoco Ranger Station Road. It is not marked, but there should be an OSP sign
placed shortly after you turn.
Zero your trip meter again and travel 8.4 miles, until you come to a Y in the
road just past the Big Summit Ranger Station (B).
Zero trip meter again, stay right on NFS 42 and go 19 miles to NFS 4240 (C).
Turn right onto NFS 4240 and proceed for 2.7 miles, turn right onto NFS 800 (D).
Go 1.5 miles west on NFS 800 and you will arrive at the OSP site.
From eastern Oregon, eastern Washington, & other states:
Coming from places east of Indian Trail Spring, there are several options. From the
north and east several good paved roads lead eventually to the town of Mitchell along
Hwy 26. It is recommended that those coming in from this direction continue west on
Hwy 26 to the turnoff for the Ochoco Ranger Station Road.
There are several gravel Forest Service roads that can be taken if one has an Ochoco
National Forest map and feels comfortable with navigating back roads. But it is always
a good idea to contact the Forest Service right before OSP to make sure these roads are
open. From the southeast, the main roads will take you through Bend and then to
Prineville. Hwy 27 is a shortcut available off of Hwy 20 to Prineville, it is graveled
from Hwy 20 until the Prineville Reservoir where it becomes paved.
