Priest Lake Road Trip, Day One the Thoroughfare, Upper Priest Lake and the Sliding Rocks.

On Tuesday I made the two and a half hour drive to the north end of Priest Lake with my camping gear. I had a reservation at the Lion Head unit of Priest Lake State Park.

The first thing I noticed at Lion Head is that this amazing wreck that I photographed years ago has finally fallen apart to the point that it isn’t all that recognizable anymore. This old wreck is right next to the boat ramp. That’s my old rig in the background with my kayak on top.

On a bright sunny day were the temps were heading into the triple digits, I launched my kayak at 9:00 AM and made my way across aptly named Mosquito Bay towards the entrance of the channel that connects Lower Priest Lake to the upper lake.

Looking back across Mosquito Bay towards the campground I noticed a notch in the mountains east of it. If I had time after my ride my plan was to check out a place about six miles up that valley. On the right side of the photo you can see the end of the replacement breakwater that protects the outlet of the Thoroughfare.

The Thoroughfare is an about two and a half mile long flat water stream that connects the two lakes. The entire course of the waterway is a strict no wake zone which makes kayaking it much more enjoyable than it otherwise would be.

As it is wide and relatively deep, the waterway has a minimal current and the paddling is easy. A lazy river indeed, at least after the snow melts. I read that it can be very challenging in the late spring.

About half way to Upper Priest Lake, a small stream called Caribou Creek flows into the waterway from the east. It is just big enough to push a kayak up about a thousand feet and around several bends. The ice cold water is crystal clear.

Caribou Creek was so cold I could hear my kayak contracting from the temperature difference. My feet got cold in a hurry too. Not a place you would want to go for a swim.

It was fun pushing it as far up this stream as I could in my Free State America brand kayak. This tree across the creek finally told me I shall not pass.

It was a short trip back to the Thoroughfare. I wish I could have traveled up this amazing creek all day, but even if I got around the deadfall across the stream, it was getting awfully shallow in a hurry.

Around one more bend is the lake with the Selkirk Mountains in the background.

As soon as you enter Upper Priest lake there is a camping area complete with bear boxes and picnic tables on the east side of the river. Here is where the rules for the lake are posted. Upper Priest Lake is a no water ski zone. Tubing and wake boarding are prohibited as well.

Upper Priest is a lot smaller than the main or Lower Priest Lake, but it’s still an impressive body of water at about two miles long north to south and an average of half a mile wide. The deepest spot is about 119 feet below the surface.

This interesting rock is well off shore near the south end of the lake.

Rocky bluffs dominate the eastern shoreline.

About two thirds of the way towards the north end of the lake I found this wonderful little beach and had it to myself. By now it was hot so I cooled off in the clear blue water. It almost looked tropical.

It would have been a nice place to camp. There are several beaches mostly on the eastern side of the lake and most of them had someone camping or visiting in a boat. This one was unoccupied.

The Selkirk crest is east of both Lower and Upper Priest Lakes. Many of the granite peaks are over seven thousand feet above sea level making them the highest mountains in the Idaho panhandle.

Four and a half hours after I started, I was back at my campsite and took another swim, this time in Lower Priest. This is the beach behind my campsite.

The kayak trip in itself would have made for a successful trip, but I still had five or six hours of daylight left so I decided to check out the Natural Sliding Rocks east of the campground.

This stream, Lion Creek enters the lake just south of the campground. A forest road follows it up the canyon for five miles before it ends at a trailhead for the sliding rocks.

Large granite outcroppings loom over the trailhead. Here you’re getting into the heart of the American Selkirks. This mountains continue into Canada.

The peaks on the south side of the creek are even bigger.

The rocky single track trail was a little over a mile and a half long each way. It had a bit of a grade and numerous small stream crossings, one of which was at the base of a pretty little waterfall.

About half a mile in I came to this beautiful place with bare slabs of granite and open views down the canyon. It was a nice place to linger but these are not the sliding rocks. These rocks would kill you if you tried to slide down them.

The trail overlooked the creek at many places. Here a deeper pool of emerald green water made for a nice picture.

I love me some giant red cedars and here I did come across a nice grove of old growth. By now the rays of the sun were noticeably hitting the ground at a lower angle indicating time was getting short.

Just before the Natural Sliding Rocks, the trail forces you to cross Lion Creek itself. It was about mid thigh deep and extremely cold.

And finally I reached the sliding rocks. I wasn’t about to try them myself. I was the last person here for the day and an injury would have been a big problem. Beside that, I didn’t feel like hiking the mile and a half back soaked and cold.

I heard there was a sizable waterfall or to be more accurate a cascade just above the sliding rocks so I found it. I pushed a little further looking for the pool at the top in the failing daylight, briefly lost the trail and decided that it was time to turn around. This is a popular place for folks to visit, but the idea of being the last one out in the dimming light and knowing there are serious critters in the Selkirks encouraged me to make good time on the way back.

On the way out I paused to take one more photo of this impressive cleft in the granite canyon wall. Those are probably one hundred foot tall trees on the top.

Just before the trailhead I caught up with a few stragglers with kids in tow so I grabbed one more photo, this time of that pretty little waterfall I saw on the way up. Next came the five mile drive back down the canyon to the campground on the lake.

Due to the heatwave dusk turned into a purple haze as I enjoyed the view from behind my campsite. I’m glad I wasn’t the only one kayaking on this beautiful day on this beautiful lake.

I called it an evening and made plans for the next morning. A four and a half hour paddle followed by a three and a half mile hike and two lake swims made for a full day, oh and let’s not forget the two and a half hour drive to the campground.
