Grants Pass Area Hiking Medford/Ashland Area Oregon Trip report

Cathedral Hills and Sterling Mine Ditch Tunnel – 05/02/2023

The second day of our Grants Pass vacation had the highest chance of rain showers with a forecast of 40% chance. We had a pair of hikes planned for the day. The first was a tour of the Cathedral Hills trails system just South of Grants Pass.

We made the roughly 10-minute drive from our cabin in Grants Pass to the Espey Trailhead arriving just before 7am.

We had seen one of the two wildflower species that were on our bucket list for this trip the day before. Red larkspur and been blooming in good numbers along the Rogue River Trail (post) and today we were hoping to check of the other, Indian Warrior.
IMG_6763The area is home to a good number of wildflowers that bloom throughout Spring and Summer.

Sullivan’s featured hike here is one of four short hikes that make up hike #83 – Grants Pass Nature Trails (“100 Hikes/Travel Guide Southern Oregon & Norther California” edition 4.2). He describes the 3.4-mile Outback Loop. We were hoping to add more of the trails to our hike and decided on modifying the featured hike by adding on the Skycrest Loop and Ponderosa Pine Trail.

As was the case on our hike the day before we spotted our bucket list flower at the trailhead.

We started the Outback Loop in a counter-clockwise direction climbing 1.1-miles to a junction at a saddle. The Indian warrior was blooming in mass along with many other wildflowers.

At the saddle we turned right onto the Timber Riders Trail then veered right after approximately a tenth of a mile following pointers for the Skycrest Loop.

We hiked the Skycrest Loop counterclockwise. There were a few different flowers along the loop.

When we got back to the saddle and junction with the Outback Loop we got confused and wound up sticking to the Timber Riders Trail which was the furthest to the right.
IMG_6900Even though it didn’t look familiar we both thought we’d come from the trail to the left earlier when in fact that was the continuation of the Outback Loop.

We followed the Timber Riders Trail for 0.9-miles thinking we were on the Outback Loop then we came to a junction with said loop and realized our mistake (after looking at the map). It had started raining at some point along this stretch and as a bonus a thunderstorm was heading our way.

We turned right back onto the Outback Loop and picked up our pace a bit. We did decide to stick with the plan of detouring onto the Ponderosa Pine Trail in hopes of seeing a 117′ tall knobcone pine that is registered as the largest in the U.S. We turned right onto the Ponderosa Pine Trail but a combination of heavy rain, increasingly close lightning, and no signage for the tree caused us to miss it entirely.

IMG_6922Back onto the Outback Loop.

Once we’d turned right onto the Outback Loop it was just over three quarters of a mile back to the Espey Trailhead. We were pretty well drenched by this point (we hadn’t put our rain gear on, just our pack covers) and hustled our way back to the car.
IMG_6925Quite a bit more water on the trail as we finished up.

In the end our hike here came to 5.4 miles with about 450′ of cumulative elevation gain.

We decided to retreat back to our cabin and wait out the weather. We put our wet clothes in the dryer and relaxed for a bit until things began to clear up. A little after 11:30 that happened, and we headed back out with dry clothing and shoes. For our second hike of the day we were tying up a bit of a loose end on a featured hike that we’d already checked off as done, the Sterling Ditch Tunnel. In June 2017 we had done an 11.8-mile loop starting from the Deming Gulch Trailhead. (post) We had counted that toward the featured hike, but it was actually part of the “Other Options” for the entry. In most cases the other options include part of the main hike and so we count those but, in this case, none of that previous loop was part of the 4.8-mile loop that is featured.

The featured loop Sullivan describes begins at the Tunnel Ridge Trailhead, passes by the Sterling Mine Ditch Tunnel, and ends with a 0.6-mile road walk between the Bear Gulch and Tunnel Ridge Trailheads. When road walks are involved, Sullivan tends to end the hike with them, but we prefer to start with the less exciting road walk so we opted to start at the Bear Gulch Trailhead instead. (There is less parking available at Bear Gulch so on busier days parking here might not be an option.)

The road walk was pleasant as road walks go and we soon found ourselves at the Tunnel Ridge Trailhead.

The trail climbed gradually for a mile gaining a little over 500′ to a junction on a saddle.

IMG_7007Couldn’t really get a good picture but this might be a bushtit.

IMG_7009There were a couple of nice benches along the trails here.

IMG_7024At the saddle a faint trail continued straight ahead toward the Little Applegate Trailhead. It didn’t appear to get much use.

We followed the pointer for Bear Gulch and quickly found ourselves at the tunnel. Built in 1877 the tunnel is part of a 26-mile long ditch used to divert water from the Little Applegate River to the Sterling Gold Mine.

IMG_7031I didn’t go all the way through so as not to disturb this napping bat.

From the tunnel the trail follows the ditch and sometimes uses it as it traverses the hillside toward Bear Gulch.

We turned left at a sign for the Bear Gulch Trailhead and followed this path a mile downhill back to our car. This trail seemed a bit steeper than the one leading up from the Tunnel Ridge Trailhead so whichever you start at it seems best to do the loop counterclockwise.

IMG_7126There was a decent amount of water running through parts of Bear Gulch as we neared the trailhead.

This loop came in just under five miles with 550′ of cumulative elevation gain giving us a total of 10.3 miles and 1000′ for the day.

After the morning drenching and surprise thunderstorm the day turned out really nice with partly sunny skies and some of the warmest temperatures that we’d have all week. Happy Trails!
