Mcgrew Trail

Sunday, August 12, 2018

Alt Names

O'brien, Siskiyou National Forest, Grants Pass, Oregon Caves, Sourdough, Sourdough Camp, Mcgrew 4wd Trail, Rock Creek, Elk Creek, Illinois River, Biscuit Creek, Cedar Springs

Last Known StatusVariable Schedule  (special use permit required)

This is a remote area that mainly consists of gravel roads and 4x4 trails. The climbs are gradual (not too steep) but some sections of the trail are pretty rocky. There is a nice staging and camping area next to the stream on the left main entrance at N42.01.615 W123.46.079. You can stage here or drive further. Follow the main road up the mountain, past the gravel pit, and bear right at the fork (go through the yellow gate) and look for a large unmarked open area on the right. This is the actual trailhead.

The trail is primarily traveled from east to west, ending near Sourdough Camp. Sourdough Camp can also be reached by heading about five miles south past McGrew Trailhead on Lone Mountain Road and taking the turnoff for NF-4402/Wimer Road heading west.

Visitors should be aware that this trail is only open to OHVs with a special use permit. The trail also has seasonal closures to help reduce the spread of Port Orford Cedar Root Disease. Those looking for rocky 4x4 trails that don't require a special use permit should check out Rattlesnake Ridge, which is about an hour south off 199. Dirt bike riders should check out High Dome or Elk Camp Ridge.

Some other recommended activites in the area are the Oregon Caves National Monument (north on 199), and the redwood forest (10-15 miles south on 199).

This photo was taken near the main trailhead.  The road is wide and fairly easy to start.  It gets a little bit more narrow and rocky as you go but nothing too challenging.

Scenic view of shallow stream flowing over river rocks surrounded by pine trees.

You will cross over this small stream on the way in.  Great scenery, crystal clear water.

Scenic view of forest and 4x4 trail.

One of many scenic panoramic views to be had from the main trail.  First time ATV riders could have a blast.

There are numerous side roads that dead end quickly.  After taking a couple you'll realize that none of them go anywhere.

Close up photo of shallow stream surrounded by large river rocks.

This small creek is the perfect place to cool off, but watch out for the crayfish that lurk at the bottom!  You can stage very near where this photo was taken.

Another shot of the play area at the gravel pit.  It was fun enough to mess around for a few minutes.

This is a bridge crossing for the stream along the main road.  We didn't know the area so we staged right near the entrance.

Some of the side roads get very little traffic.  There were alot of downed trees and dead ends.

This was a typical fun section in the first mile of the main trail.  Lots of turns with slight climbs and dips.  Not too many rocks.

Some sections of the trail are a bit rocky.  It gets rockier than this too, but not really difficult or steep.

This place may not be the single track twisty that you were hoping for but still, it is a gorgeous ride.
