Diamond Peak Area High Cascades Hiking Oregon Trip report

Yoran Lake – 09/05/2026

September began with some much-needed precipitation including snow at higher elevations. Checking the forecast for a hike to start the Labor Day weekend revealed that the Willamette Pass area was expected to be partly sunny Saturday morning before a chance of showers and thunderstorms developed later in the day. I narrowed it down to two loops, one in the northern end of the Waldo Lake Wilderness the other in the northern end of the Diamond Peak Wilderness. Both loops would have us visiting multiple lakes however the northern end of the Waldo Lake Wilderness has been through two large fires in the past 30 years while the northern end of the Diamond Peak Wilderness has not endured a large fire. There would be more views hiking through the fire scars, but we weren’t sure if the partly sunny forecast meant that the Cascade Peaks would be visible, so we opted for the Diamond Peak Wilderness.

The loop we’d chosen was Midnight and Yoran Lake, a hike we’d done back in 2014 post. We also hiked half of the loop on our longer loop around Diamond Peak (post). For both of those outings we’d parked at the Trapper Creek Trailhead. To mix things up a bit (and cut 1.4-miles from the total distance) we decided to begin the loop from the Pengra Pass Trailhead located near the Pacific Crest Trail.

The next decision to make was which direction to hike the loop in. We chose clockwise for two reasons. The first being that we would be starting out on a short downhill which would allow us to warm up a bit versus starting with a climb. The second reason was that the longest stretch without passing near a lake at almost 4-miles and we prefer getting the less exciting stretches done first. Speaking of less exciting the first 0.2-miles followed a gravel road before reaching the Whitefish Creek Trail.

The Whitefish Creek Trail immediately entered the Diamond Peak Wilderness and gradually climbed for 0.7-miles to a junction with the Yoran Lake Trail.

We turned right onto the Yoran Lake Trail and climbed steadily for 2.8-miles to the first (unnamed) lake.

The Yoran Lake Trail was well maintained with no trees down across the trail.

We continued past the unnamed lake and in just over a mile came to a familiar unsigned junction next to a dry creekbed.

The trail to the right was a user created trail until 2019 when the Forest Service officially decided to connect the Pacific Crest Trail near Lils Lake with the Yoran Lake Trail. Before continuing on the Yoran Lake Trail we veered left and climbed steeply up the hillside to Karen Lake.
IMG_1593

We’d camped at this lake on the final night of our loop around the mountain. We took a break along the lake shore near where we’d camped before and waited to see if Diamond Peak, which was now partly shrouded by a cloud, would make a full appearance.
IMG_1594

IMG_1595

We spent half an hour at the lake watching the clouds tease a reveal only to have more arrive.
IMG_1607

IMG_1610

IMG_1621
So close.

After 30-minutes we were starting to get cold from not moving around so we continued on our loop hoping that maybe things would clear up when we reached Yoran Lake which was less than a quarter mile away.

The trail climbs above the lake on a rocky shelf where we again stopped to give the clouds some time to move on. It took about 15-minutes for that to happen, and we finally had a view of the full mountain.

Mount Yoran was not dealing with clouds.

After getting the view we’d been hoping for we continued on. The trail passed several more viewpoints above Yoran Lake before passing through the forest and arriving at Lils Lake.

We turned right onto the PCT and started a stretch of trail that passed a number of named and unnamed bodies of water.

After visiting Hidden Lake we continued on the PCT passed several more unnamed bodies of water before arriving at Arrowhead Lake a mile from Hidden Lake.

After a short break at Midnight Lake we continued our loop. It was 0.2-miles from the lake to a junction with the Midnight Lake Trail and then another 0.9-miles to the Pengra Pass Trailhead.

This is a nice loop with a variety of lakes and few good mountain views (when the clouds cooperate). We were a little surprised to have only run into 9 other hikers all day. The trails were also in excellent shape with only a couple of small logs to step over. The fresh snow on Diamond Peak was a nice bonus and a good reminder that Fall is on the way. Happy Trails!

Diamond Peak Loop Days 3 & 4 – 08/24 & 8/25/2020

**Note the 2024 208 MF Fire burned over a portion of this hike near Blue Lake.**

Morning of day three was a little less smoky and we were eager to get an early start to try and avoid doing the long climb from Notch Lake to the divide above the Pacific Crest Trail in the afternoon heat. We were up with the sunrise and after coffee and some granola we were back on the Diamond Peak Trail heading north.
IMG_4667

IMG_4676

IMG_4678Some blue sky again.

The trail lost 500′ of elevation over the next mile including some steeper drops before arriving at a junction with the Happy Lake Trail.
IMG_4679Happy Lake Trail junction.

We detoured left here for the half mile hike down to Happy Lake.
IMG_4680

Unlike the Blue Lake Trail the Happy Lake Trail was fairly level losing less than 100′ of elevation before passing by a large meadow and arriving at the lake.
IMG_4687Just a small part of the meadow.

IMG_4692

IMG_4693

We set our packs down and then followed a path to a hard to see waterfall along the lakes outlet creek.
IMG_4698

IMG_4699

It might have been hard to see the whole thing but it sounded wonderful. There were also a lot of wonderfully ripe berries in the area.
IMG_4710

A viewpoint along the cliffs gave us a look at the rocky pillar of Mt. Yoran which we would be passing on the way to the divide later in the day.
IMG_4713

After enjoying the lake and waterfall (and consuming quite a few berries) we returned to the Diamond Peak Trail and continued on. It was a mile and a half to our next trail junction and we were pleasantly surprise to find that this stretch of the trail had seen some recent maintenance which made the going that much easier.
IMG_4717

IMG_4721

IMG_4725We think this was Bear Creek. Other than the outlet of Happy Creek no other creek beds had flowing water on this side of the mountain.

IMG_4727Diamond Peak from the trail.

At the junction we left the Diamond Peak Trail and turned right onto the Diamond Peak Tie Trail.
IMG_4730

IMG_4731

This trail had also recently been cleared and was lined with huckleberries. It was also apparent that this was a much wetter area than we’d been in so far along the loop which meant mosquitoes which kept us from stopping for long.

IMG_4746The creeks were still dry though.

After two miles on the Diamond Peak Tie Trail we arrived at the Vivian Lake Trail. We had been on the other end of this trail when we visited Vivian Lake in 2013 (post).
IMG_4753

IMG_4755

We turned right onto this trail and in a quarter mile arrived at rock rimmed Notch Lake.
IMG_4759Small unnamed lake just before Notch Lake.

IMG_4760Another little lake/pond near Notch Lake.

IMG_4761Notch Lake

This was a really neat lake and we would have loved to stick around a bit but all the standing water in the area made for a lot of pesky mosquitoes so we unfortunately had to move on pretty quickly.
IMG_4766

Approximately .2 miles beyond Notch Lake the Vivian Lake Trail veered left and the Mt. Yoran Trail split to the right.
IMG_4776

IMG_4778

The Mt. Yoran Trail climbed at an increasingly steep grade over the next 1.7 miles before gaining a ridge and leveling out.

The mosquitoes weren’t nearly as bad here so we were able to take a nice long break before resuming our trek.

IMG_4853Thank goodness it was a seed.

When it was time to continue we followed the Mt. Yoran Trail around Divide Lake and past two smaller unnamed lakes before making the steep 300′ climb to the divide.

After crossing the divide the trail dropped down to the Pacific Crest Trail.
IMG_4876

We turned left here and followed the PCT downhill for 2 miles.
IMG_4879

Along the way we bumped into another backpacker who was doing the same loop in the other direction. We were able to let him know about the trail conditions ahead and he let us know that the Yoran Lake Trail now continued past Yoran Lake all the way to the Pacific Crest Trail. When we had done our Yoran Lake hike in 2014 (post) we had bushwacked from Yoran Lake to Lils Lake and the PCT so this was welcome news.

We had originally intended to set up camp here but there were already a number of people at this lake and we weren’t (I wasn’t) feeling all that sociable so we decided to press on to Karen Lake which was less than a quarter mile away. I don’t have a lot of patience to begin with and my Garmin had quite working at Divide Lake due to the memory being too full (at least that’s what I hoped it was, and it was) and that had put me on edge.

IMG_4913Right hand fork to Karen Lake.

Things were much more solitary at Karen Lake aside from a lone duck patrolling the waters.
IMG_4916

IMG_4917

We had camp set up by 3pm and spent the rest of the afternoon and evening enjoying the lake (and the decreasingly smoky skies).

IMG_4957

IMG_4963Is this a tadpole? We first thought it was a newt then a fish but it’s got feet.

While the smoke was clearing there were more clouds coming and going, but we had kept a close eye on the forecast before leaving and there hadn’t even an inkling of a chance for precipitation for the trip or the next couple of days.
IMG_4965

IMG_4968The moon was really showing up well over the mountain.

We had just gotten settled in the tent for the night when the light outside turned orange. I threw my clothes back on to try and catch the sunset which was spectacular.

After a whole lot of picture taking I got back into the tent and we tried to sleep. It didn’t come easy though. I don’t know if knowing we had less than 5 miles the next day before heading home had us excited or if our spot just wasn’t all that comfy but we had a hard time falling asleep. Then just after 4am we both woke up for some reason. Heather was the first to realize why when she asked why her quilt was wet. It took a moment to register but it was raining! Luckily we always carry our rain fly even if there isn’t any rain in the forecast for just such an occasion. We hopped out of the tent and threw it on before it really started to come down which kept everything pretty dry. We heard a couple of rumbles of thunder in the distance and I never could fall back asleep. The showers had mostly stopped by 5:30 am when we decided to start packing up.

IMG_5019Another light shower passing over as we were leaving.

After some coffee we were on our way. It was before 6:30 so it wasn’t very light but it was plenty light for hiking.
IMG_5025Some funny looking beargrass along the trail.

A half mile from Karen Lake we crossed the dry bed of Karen and Yoran Lakes outlets.
IMG_5029

In another half mile we passed a small unnamed lake.
IMG_5035

We encountered a little blowdown along this trail but nothing too bad.
IMG_5045

Two miles from the little unnamed lake we were passing a large meadow on the left when we noticed another lake at it’s end. I decided to go check it out and left the trail. As I neared the meadow a deer jumped up and splashed off into the grasses.
IMG_5049The lake doesn’t show a name on the map but West Bay Creek flows out of it (of course it too was dry at this time of year).

Over the next three quarters of a mile we encountered two little girls hats laying in the trail. We picked them up and left them at the junction with the Whitefish Creek Trail not knowing if the owners were still at one of the lakes and if so which way they’d come from.
IMG_5066

We turned left at this junction following the pointer for the Trapper Creek Trailhead. It was just under half a mile to the closed bridge over Trapper Creek.
IMG_5071

While the bridge didn’t appear to be in that bad of shape we honored the posted closure signs and made our way down to the ford.
IMG_5072

IMG_5077

IMG_5079

The water was cold but it was an easy ford and with only .2 miles left to get back to the car we didn’t have to deal with wet feet for long. We completed our loop having covered 13.1 miles on the third day and 4.7 on the final day for a grand total of 48.4 miles. The trip allowed us to cross the Diamond View Lake, Marie Lake and Diamond Peak, Corrigan and Blue Lakes, and Divide Lake hikes off of our featured hikes to-do list leaving us with just the Erma Bell Lakes hike to complete the 100 featured hikes in Sullivan’s Central Cascades book. Happy Trails!
