BOU AVENUE
Chopaka Mountain And Joe Mills Mountain

On 24 July 2026, Zosia Zgolak and I climbed Chopaka Mountain located about twenty-five kilometres west of Oroville, Washington.  A fairly easy ascent route via the south ridge is described in Summitpost.org.  Several other officially-named summits in the vicinity can also be tagged at the same time, but we would ultimately add only Joe Mills Mountain.  Accessing both mountains requires a lengthy drive along forestry roads, but the roads are generally pretty good and should be suitable for most 2WD vehicles.

From US Highway 97 in Oroville, turn west onto 12th Avenue.  Drive 450 metres and cross a bridge over Similkameen River (12th Avenue becomes State Highway 7).  Continue for another 18.5 kilometres and turn right at a T-intersection with Loomis-Oroville Road.  Drive 18.5 kilometres to the community of Loomis and veer right at the intersection with Main Street.  Continue for another 3.4 kilometres and turn left onto Toats Coulee Road.  Drive 2.2 kilometres and turn right onto Lower Chopaka Lake Road (2WD gravel).  Drive 5.4 kilometres (with 550 metres elevation gain) to a split.  Keep left on Chopaka Mountain Road and drive 2.5 kilometres to a second split.  Stay left and drive 5.5 kilometres to a T-intersection with Ninemile Creek Road (alternate 2WD approach from the south via Toats Coulee Road).  Turn right and drive 3.7 kilometres to Cold Springs Campground (free with Discover Pass; vault toilet available).  The trailhead (Discover Pass required) is another 350 metres further up the road.  About half a kilometre beyond the trailhead is a loop of extra campsites with another vault toilet at road's end.

From the trailhead, Zosia and I followed a dirt road northward and soon passed a locked gate.  About 600 metres past the gate, we abandoned the road and headed up the forested slope to our right.  The bush was light here, and other than having to pass through one barbed wire fence, navigating the south ridge was easy.  As we climbed higher, the forest eventually thinned out, and we found ourselves on more rocky terrain.  Travel was still pleasant though, and we easily hiked up to the spacious summit without any trouble.  After previously enduring several days of smoky air, it was refreshing to have clear skies for a change, and we enjoyed far-reaching views during our lengthy break on the summit of Chopaka Mountain.
Zosia likes to read everything in the backcountry! At the trailhead, Zosia reads information about Loomis Natural Resources Conservation Area (LNRCA) through which goes the initial approach to Chopaka Mountain.
It's a bit of a leap of faith leaving the road, but the bushwhacking is thankfully pretty light. Zosia leaves the road and heads up the forested slope.
Might even be a good ski route in winter! Open sections in the forest like this one make off-trail travel easy.
Thankfully, it doesn't say "No Trespassing"! Zosia reaches a barbed wire fence likely marking the boundary between LNRCA and Chopaka Mountain Natural Area Preserve.
Already? We must be making good progress!

The summit of Chopaka Mountain comes into sight.

Easy Class 2 hiking here--no scrambling required!

Zosia approaches the summit block of Chopaka Mountain.

 

We're like two little Fonzies here...AYYYYYY!!! Zosia and Sonny sit comfortably on the summit of Chopaka Mountain (2408 metres).
Chopaka Mountain South is also known as Little Chopaka Benchmark, but there is another Little Chopaka Mountain further east. In this view to the southeast, part of Palmer Lake is visible beyond unofficially-named Chopaka Mountain South.
Tiffany Mountain is calling us!  Looking south, the trailhead is somewhere at the bottom of the road on a forested hump (foreground right of centre).

Big Craggy, Windy and Remmel are being added to my to-do list...

Here is a panoramic view to the west.

 

Snowy Mountain is a difficult one to access.

Joe Mills Mountain (left foreground) sits about 1.4 kilometres to the northwest.  Snowy Mountain is located north of the border in British Columbia.

 

Hurley Peak looks higher from here...but it's not! To the north is Hurley Peak.  On the horizon to the right of Zosia is Baldy Mountain which is also north of the border.
When we resumed hiking, Zosia and I opted to head for nearby Joe Mills Mountain by dropping down the north slopes of Chopaka Mountain.  We had no problems intersecting a partly reclaimed road running through the dip between Chopaka Mountain and Joe Mills Mountain.  We turned left onto this road, but instead of following it over a subsidiary bump, we took a brief short cut to directly gain a jeep track running across the south slope of Joe Mills Mountain.  The jeep track winds around to the west ridge and continues past a barbed wire fence.  We left the jeep track here and simply climbed alongside the fence all the way to the summit.

After tagging the summit, Zosia and I dropped directly down the south slope and regained the partly reclaimed road at a saddle between Joe Mills Mountain and the aforementioned subsidiary bump.  We descended this road to the west which included another short cut down a very steep but well-defined trail.  We eventually reached a junction with another overgrown road heading southward.  This road is the very same one we were briefly following past the gate at the start of the trip.  We simply hiked this road all the way back to the trailhead.  The road annoyingly undulates a fair bit with at least one big uphill section, but there are also some creeks along the way which provided refreshing relief from the warm temperatures.  Upon returning to our car, we drove out of the area on different back roads which was a bit of an adventure in itself, but fortunately, we made it to our next destination without incident.
I guess no one has driven this road in awhile... Heading for Joe Mills Mountain, Zosia walks along a road that has been partly reclaimed by lupines.
Probably would've been just as easy to head directly straight up here. Zosia takes a short cut aiming for a jeep track running across the south slope of Joe Mills Mountain.
But it doesn't go all the way up to the summit. Zosia gains the rough jeep track.
Who is Joe Mills? Sonny and Zosia stand on the summit of Joe Mills Mountain (2357 metres).
We were on that summit only 50 minutes earlier. Here is a look back at Chopaka Mountain from the summit of Joe Mills Mountain.
Looks like another great slope for skiing! Zosia descends a road on the southwest side of Joe Mills Mountain with Chopaka Mountain visible at left.
We thought it would be best to avoid Disappointment! Zosia drops down a steep short cut trail that skips a few switchbacks in the road.  The hill right of centre is officially named Disappointment.
Not so easy--lots of ups and downs but at least there are refreshingly cold streams along the way. Zosia turns southward along the road which ultimately leads back to the trailhead.
A good, reliable car is a must to drive this long and lonely road! After the hike, Zosia and Sonny embark on a long drive through some remote terrain along Forest Road 39.
