The nearest campground is the Gore Creek Campground, a National Forest Service fee area with vault toilets and water. To get there from the Exit #180, you'll need to drive SE on Big Horn Road past the trailhead parking for the Deluge Lake and Gore Creek TH. Reservations may be made for campsites at reserveamerica.com. Other than that, there is virtually no other place close by with at-large/primitive camping. Your best bet may be to go up to the summit of Vail Pass and drive down the Black Lakes Road where there is a pullout parking area right where the road is barred from vehicular traffic and becomes the Vail Pass bike trail, east end. This is not a primitive camp location but you may be able to sleep in your vehicle.
The small parking area for the Pitkin Lake Trail has a sign warning about a 2-day parking limit. If planning on being there longer, call the Vail Police Department - Enforcement Division and ask for permission to park there longer. Be prepared to provide license plate and vehicle description.
The trail begins by ascending gently along the east side of the stream, then crossing on a sturdy bridge. A short distance farther on, it abruptly begins an incredibly steep ascent with well-positioned logs to reduce runoff and provide steps for the arduous climb with full packs. For the next half mile, you might as well be climbing a mountain, but after that, the trail begins to level off, still maintaining some distance from and above the creek. Overall, this trail is in fairly good condition and after the initial section was not too arduous.
After about two miles up the trail comes right beside the creek. After the section near the creek, the trail remains very moderate until it crosses an open meadow and then begins climbing up to another bench level. At about 3.25 miles in the trail crosses the west fork of Pitkin Creek and there is a large campsite past that crossing. In 2010, the campsite was not well-used. It's a short distance before the trail makes a left turn to begin a steep ascent out of the valley to Pitkin Lake. We are calling this the "lower campsite." It can be used as a base camp for Mt. Solitude, Peaks X and Z. The waterfall shown on the map is somewhat obscured from here.
After passing the campsite, the trail begins climbing steeply for about 1/3 mile before leveling off in the upper valley that leads to Pitkin Lake. We arrived in the vicinity of the lake in about three hours from the trailhead. We found a very nice site 100 yards east of the trail and down from the lake by about 150 - 200 yards. It had some nice trees for some shelter, a fire ring and several level spots for tents and was located right at the foot of the prominent south ridge of East Partner. Close by and down a little from the campsite are some scenic ponds with a view down the valley. This is the "upper campsite" and can be used as a base camp for both Partner summits and Peak Q.
Our route for Peak X begins from the "lower campsite" along Pitkin Creek that's 3.75 miles upstream from the trailhead. If starting from Pitkin Lake, adjust accordingly. The Round trip mileage and elevation gain are measured from the trailhead. RT mileage and elevation gain from the lower campsite only would be 4.5 miles and 2,635 ft.
From the lower campsite head back up the east fork of Pitkin Creek, utilizing the faint trail that follows on the east side of the creek. (You will need to cross the creek at the easiest place you can find near the campsite.) One section of the trail will take you up on a flat shelf where there's a little flat area with nice grass, trees and surrounding protection from some rock outcrops. This could also serve as a nice campsite. After here, the trail works down to the creek again where you will pass some small ponds and will wade through lush flowers and grass that can be damp from previous days rain.
In about an hour you can make it up to the head of the valley where you will need to start climbing up to “Useable Pass.” See our map for the location of this pass. It may require another 45 minutes to hike up to the pass. The hike up to the pass is fairly easy over mostly tundra and smaller broken rock & rubble. Useable Pass is just a means of crossing the ridge south of Pt.12,710 and accessing the slopes of Peak X or dropping into the headwaters of the north fork of Boulder Creek. The east side of this pass is extremely steep for the first 100 feet down or so. Carefully work your way down, descending on mostly unstable gravel and dirt. Lower down, you will see an opportunity to head over to the base of a cliff wall to the left. At the base of the wall, there is just enough flat space to walk along on more stable ground. In fact, there appeared to be a faint trail here. Lose perhaps another 100 feet in elevation before deciding to contour over toward the saddle between Peak X and 12,710. Hike on mostly rubble, small boulders and small shelves of tundra. In short order, gain the SSW ridge of Peak X. From here on, it is just another ridge hike. Most of it is class 2 or 2+ with a few scrambles around boulders, small cliffs or other obstacles, but in all, you should be able to follow the ridgeline. We found the ridge to be stable, a welcome relief from previous days on the Partners and Peak Q.
Time from the lower campsite to the summit is under three hours. We felt some relief that this peak was a little easier than anticipated. The descent from Useable Pass was probably the most difficult part. Either return as you came or continue on to Peak Z.
Peak Z is sequenced with Peak X. One way mileage and elevation gain from Peak X will add an additional 1.25 miles and 1,350 feet of gain. On the return trip, you'll also have to gain between 400 and 500 feet elevation to get back over "Usable Pass." RT mileage and elevation gain from the lower campsite will be 7.25 miles and 4,485 feet of elevation gain. In this terrain, that's a serious enough day as it is.
The connecting ridge over to Peak Z looks pretty rugged, by way of Peak Y, so we ruled that option out, partly in the interest of time and partly because we didn’t want to find ourselves cliffed-out. Head back along the SSW ridge of Peak X to where you can start down the East ridge The ridge from the summit appears to be fairly difficult, but a better view of the east ridge prompted us to stop and reconsider. After some more study, we decided to attempt this east ridge, even though we had no information regarding it. For several hundred feet you can descend with relative ease, even though it is fairly steep. There was a drop further down where we could not see for sure what would happen, but thought we could manage it. So down we went.
As we descended this unknown ridge, the more we went down, the steeper it became. When we came to the section that appeared from above to drop off some, we left the ridge and began descending off to the right on steep tundra slopes with some rock. At times, it was so steep that we found ourselves gingerly crab-walking down short sections. Below us we could see that the ridge intersected a large couloir/trough that led directly south down to the more level, valley terrain. We headed over to the head of this couloir and then began descending it. There was some nice scree that allowed us to plunge-step our way down rapidly for a while, but it gave way to more rocks until things began to level out at about 12,000 feet. We were relieved to have successfully negotiated this descent without any overly difficult problems. Once out of the couloir, we turned eastward, walking over more gentle, tundra terrain now, interspersed with rock outcrops and flowers. We hiked past a beautifully colored shelf lake just above 11,880 feet with a few small trees around it. Once past the lake, we began ascending toward Peak Z.
Most of the lower ascent section is over tundra, with some boulder fields thrown in. Instead of going for the saddle/low point between Peaks X and Z, we decided to head right of the connecting ridge toward a steep slope that appeared to have some tundra, at least lower down, and that climbed up through a steep, rocky outcrop that guarded the flat south ridge of the peak. This flat area is very distinguishable on Peak Z from afar. The ascent through here is steeper than you might anticipate and we found ourselves using a cliff wall section for handholds as we ascended. Further up, we had to work our way through boulders and steep scree and then finally broke through to the flat southeast ridge. At this point, you are little more than 200 feet below the summit to the north. The remainder of the hike is easier, but still involves a little scrambling around boulders, etc. Looking back at the ridge between Peaks X and Z, we were glad we had not attempted a traverse. It was a very rocky ridge and had at least one section that dropped vertically. It most likely would have become a minimum of 4th class scrambling or even some 5th class work. Perhaps there's a report on it somewhere.
It took us about five hours to arrive at the Peak Z summit from the lower Pitkin Creek campsite and Peak X. Across the Boulder Creek drainage to the south, you are able to view Keller Mountain. To the north, there's a great view of Peak L, one the most difficult summits above 13,000 feet in this range. To return, descend back to the flat ridge area and if looking for some variety, take the southwest ridge back to the saddle and then turn south toward the bench area above 11,800 ft. You can follow that bench back to Useable Pass. We should have taken that SW ridge to begin with. Hiking down it was easy compared to how we went up and it was no problem hiking down to the bench level. A short distance beyond the shelf lake at 11,880 ft., the real fun begins. Following the bench southwest past the lake, we came to what we had avoided earlier in the day – a field of boulders that stretched a good 2/3 mile, all the way back to the base of Useable Pass. By descending the east ridge of Peak X, we had avoided almost all of this (and that was another motive for taking that descent), but now it's time to pay the piper.
Make your way west slowly and tediously, across the boulders of all shapes and sizes. Now a quick jaunt across a boulder field can be somewhat entertaining, but 2/3 mile is just plain pain in the rear, especially towards the end of the day. It seemed to take forever to get across and to the base of Useable Pass, (12,380 ft.) but we finally arrived there and then made the 300 foot ascent back up. The last 100 feet are difficult as anticipated, but we made it without injury and then began the hike back down the Pitkin drainage to our campsite. Return either to your campsite or the trailhead. If you manage to do this entire hike in a day, you are to be congratulated.
