For the final hike of our trip we’d chosen Aneroid Lake. This would be our 99th featured hike out of the 100 in William L. Sullivan’s “100 Hikes Eastern Oregon” 1st edition (2022) and our 499th out of the 500 featured hikes that we’ve been working on for a number of years now (post). Sullivan gives two options for this hike, a moderate hike gaining 1150′ of elevation in just under 4-miles (round trip) to a waterfall on the East Fork Wallowa River, or the difficult hike to Aneroid Lake gaining nearly 3000′ of elevation in what he lists as a 12-mile round trip. Other reports put the hike to Aneroid Lake at just over 13-miles RT but agree on the elevation gain. Our plan for the day was to once again split up and go our own paces with Heather’s goal being the waterfall and mine being the lake. Heather would return to the trailhead and then head to the Trailhead Coffee stand and do a little shopping in the Wallowa Lake community while she waited for me to get back. We figured that the hike to Aneroid Lake would take me anywhere from 6 to 8 hours depending on how long the hike really was and how well my legs were working after four days of serious hiking.
We began at the Wallow Lake Trailhead which we’d started two other previous hikes from, a five-day backpacking trip (post) and a short hike to B.C. Creek Falls (post). For both of those hikes we’d taken the West Fork Wallowa Trail. Today we would be using the East Fork Wallowa Trail.

The trail began by following a rocky roadbed uphill.

The roadbed soon became a proper trail as it continued uphill.

Entering into the Wallowa-Whitman National Forest.
A little over three quarters of a mile from the trailhead I came to a junction with a connector trail to the West Fork Wallowa Trail used as a loop for horse tours.

Beyond the junction the trail passed through some rocky hillsides with views across Wallowa Lake.

I never saw any but I heard a number of pikas in the rock fields.

When Heather came through the rock fields she did spot a pika.

After checking out the lower portion of the falls from access road bridge I returned to the trail and continued up to a switchback with a view of the upper section of the falls.

From the switchback the trail continued its steady climb arriving at a damaged bridge after a little over 2 miles.

Shortly after entering the wilderness the trail passed through some small meadows with fireweed and various berries.

Elderberry and baneberry
As I was pondering which animals if any might eat the different berries I spotted something brown in the fireweed below the trail. It took a moment to register what I was seeing. I had my camera out and was zooming in to try and identify it, but as soon as it lifted its head I realized it was a bear.
Zoomed in photo.
It didn’t seem to notice me so I quietly and quickly continued on trying to put some distance between myself and it. I wasn’t too thrilled when the trail suddenly made a switchback and I was headed back toward where the bear was, albeit I was now higher up the hillside. I continued with a bit of a quicker pace until I felt that I’d gotten a decent distance away then slowed a bit to avoid missing the scenery. I passed a couple of hikers on their way down who I mentioned the bear to just in case it was still there.

The damaged footbridge.
While the climb had not been steep beyond the footbridge the climb became even more gradual. Just under a quarter mile from the bridge the trail split with inbound traffic staying right.


The inbound trail traversed an exposed hillside with views down to the East Fork Wallowa River.

I arrived at Roger Lake at what my GPS said was the 6-mile mark.

It was another half mile of climbing to reach Aneroid Lake.



Sullivan’s description said to ignore a use trail on the right leading to a campsite and to continue on to another fork that led to the private cabins at Camp Halton. I passed what I believed to be the right-hand fork Sullivan mentioned just before reaching a pair of wooden benches along the trail.
The benches.
Beyond the benches I came to a second fork which I mistook for the trail to the cabins. Sullivan mentioned that despite the cabins being on a small parcel of private land the caretakers accepted respectful visitors.

There were no signs posted at all at this fork, so I proceeded steeply downhill and wound up in a campsite.
I still wasn’t sure if this was the trail to the cabins or the one Sullivan had said to ignore so I continued to follow the trail to the lakeshore.
Groundsel along the trail.

A boat docked on the lakeshore in the distance.

I decided to follow the trail along the lake shore and eventually wound up at the boat dock. At that point I realized that I for sure had taken the wrong fork and backtracked.
An inlet creek to the lake near the boat dock.
East Peak from Aneroid Lake.
I followed a different use path that climbed up from the lake a bit more gradually and wound up on the path down to the private cabins.


I started down the trail but when I got into view of the cabins I decided not to bother anyone and took some zoomed in photos and headed back uphill.



Signs for Camp Halton at the actual junction with the East Fork Wallowa Trail.
I headed back on the East Fork Trail and detoured down the first righthand fork to visit the lakeshore one last time before heading back to the trailhead.



I kept a pretty quick pace on the way back down stopping for a few photos and to let a handful of uphill hikers pass.

Arriving back at the trailhead.
According to the GPS my hike was 14-miles which lines up better with the reported 13.1-mile roundtrip vs Sullivan’s 12. The extra milage is mostly due to my taking the wrong righthand fork and then backtracking before heading down toward the cabins.

I finished in just over 6 hours and located Heather at the Little Alps Day Use Area near where we’d parked. After taking a break at the picnic table she was sitting at I changed my shoes and socks and we drove down to the Khao Neaow Food Cart to get some tasty Thai food to take back to our room.
This was yet another great hike in the Eagle Cap Wilderness which is easily our favorite wilderness area in Oregon. We’re excited that the final hike in our quest for the 500 featured hikes will be in this wilderness, hopefully a little later this year. Of course there are many other hikes in the Wallowas that we’ve yet to do so that won’t be the last time we visit. Happy Trails!
