Info: Clear all the way, no snow on trail. Parked at Princeton towers and ran / hiked up and down. I would not take a dog on this one, as there is a lot of big rocks that I saw one couple with two dogs having a hard time!

Info: Great conditions bottom to top. 1 snowfield about 40 feet long that's easy to cross. A little bit of wind going up, but not nearly as much as predicted...guessing 10-15mph on top, sunshine, and in the 40s. The "4WD" road up to the 4WD trailhead is quite easy if you have a little bit of clearance, and a little bit of wheel placement knowledge; you really don't need 4WD, just a little bit of clearance and skill. Having said that, if it were wet, you'd want 4WD. I took my stock Jeep Renegade with all-weather tires up to the camping spots above the radio towers with no issues. Be prepared to walk on rocks over half of the way!

Info: Beautiful day. No moisture on trails. 4x4 road is good enough for high clearance vehicles (i.e. lifted jeeps). It is unsafe to drive further than possible for a sedan.

Info: Summer conditions all around. Was able to drive up past the radio towers and parked at the last switchback at 11,600'. There were a few patches of snow that got slushy by afternoon but manageable. Poles very helpful as others have indicated, but no traction required.

Info: There are still 3 snowfields to traverse. They are doable without microspikes though. I recommend poles to help with footing but it is otherwise packed down. Where the trail splits off of the road initially is still covered in snow, so keeps your eyes out for a cairn on your right to mark it or keep checking your maps for where to turn after the last switchback on the road. Otherwise, all other snow is melted on the trail.

Info: Thanks so much to Omatt89 for the ski beta! I never would have normally considered Princeton in snow season. I followed his beta (and tracks) almost exactly, and skied down the far climber's right gully until the snow ran out in the trees. This was probably only a couple hundred feet past where Omatt89 traversed, and definitely not worth it. I basically did a straight traverse til I hit thick trees, then decided it would be easier to climb above the trees than bushwhack through them with skis on my back. The trees kept going higher the further I went around, so I kept angling higher, and finally, I hit the road at a snowy switchback just above where the highest car parked (An FJ cruiser went up to where a drift was covering all but a couple feet of the road and parked right before that on the road). I dropped in around 10:30, the snow was ridiculously soft, and I was sending medium roller balls by the bottom, but by then the angle was low.

Info: I hiked from the lower trailhead- started at 6am and summitted at 11am. Road is clear up to radio towers, and snow doesn't really start until the trail begins. There is snow covering the turnoff to the trail. Other than that, several large snowfields that spikes could be helpful for. I used crampons on the way up but not on the way down. Poles were very helpful overall. The ridge is pretty snowy too in spots-- didn't use any traction though. Trail very hard to follow at this point, hope hopping through scree is something you enjoy if you're headed out soon. Overall great day!

Info: 4wd rd clear past radio towers. Room for maybe 12/15 cars. Past there you can find like 4 spots. Can park 3 cars at the last switchback above treeline before road goes up to left very steeply. Some snow on standard trail. Atleast 2.5 medium sized snowfields to cross. Some more snow near the top ridge to navigate. All fairly easy but engaged style hiking. Hiking poles a luxury. Floatation or spikes not needed. Bootpacks packed down nicely but Some light postholing on way down for partner around 11/1130. Was getting very warm and no wind. I skied far right Gulley. 20 mins traverse from summit over to drop in point. Had to climb down 20 / 30 feet. Then dropped at 1045 from about 14000 feet and got extremely good flat corn. Not bumpy. A crazy good ride. Probably skied down To about 11800 ish?? and while the snow on the Gulley kept going down, I picked what i thought was easiest point to traverse back to standard trail near ridge crest by carefully Boulder hoping and climbing snow. Get these similar conditions for another 5 or 6 days maybe? Have fun

Info: Road is completely clear up to the towers, snow blocks the road shortly after that. We ascended over Tigger Peak and came back across the standard route. Going over Tigger only required crossing two short snow sections. One pretty quickly after the towers, and another closer to starting the boulder field up to the peak. The standard route had a few more snow crossings in the gullies, snow was pretty boot packed and stayed just hard enough to only post hole a few times on the way down at ~11AM. Micros could be useful, though I left mine in my pack. All in all, surprisingly summer like conditions for how early in the year it is.

Info: Ski descent of east face. Traversed North from summit before dropping off small cornice at 14020'. Continuous snow to 10,800'. Even with 30mph wind, snow was thawed at summit by 10a. Snow was a weird mix of porous melt-freeze grains with deep runnels, but actually made for some wonderful turns for over 3k. Bushwhacked up to treeline and contoured out of the descent drainage to regain the road about a mile from where we parked. Get it soon, won't last more than a couple weeks. Zoom in to see the line, lookers right of the summit.

Info: Almost summer conditions on Princeton today. Made it with our Jeep just past the radio towers. The road further than that is currently impassible with a car due to snowdrifts. Walked up the road to the chalet and went up and over Tigger (we completely missed the turnoff to the standard route that goes around Tigger due to snow). A lot of class 2 scrambling up Tigger & Princeton, minimal snow on the way up and never put our microspikes on. The top was beautiful and dry with minimal wind. We came down the standard route. There was much more snow this way and route finding was difficult with snowfields and scree. Overall took us about 5 hours round trip.

Info: Myself and 3 other people summited Mt Princeton yesterday. I started from the lower trailhead & took this route up. Returning I hiked along the Tigger-Princeton ridgeline and came down off Tigger back to the road at 11,800 ft. ASCENDING: The long switchbacks road (past the radio towers) below treeline is still mostly covered over with snow, although sometimes it had a thin rock border on the downhill side. Most of it seems to have an older, fairly solid snowshoe trench in place if you can manage to see/stay up on it. The gully crossings up higher were deep in snow and very sloppy and soft, it made for slow going and I told myself I'd return on the ridge and avoid them all a second time. DESCENDING: I like the solid Tigger-Princeton ridgeline and the view from it is incredible. Faint trails leave Tigger's' summit going toward the very end of the Mt Princeton road, and also going back toward the Mt P road/standard route junction. I aimed for the second one and most of this area was snowfields.

Info: I climbed just a day before a storm cycle but it was warm and calm. I left car at 5AM from summer trhd. Snowshoes carried from car to comm. towers where they became very useful. 1 ski pole was useful. At open slope, old avalanche debris facilitated passage across slope. Removed flotation on lower ridge near treelike. Tried to traverse upper slope toward Tigger-Princeton Col but soft snow forced my hand and I headed straight up slope to Tigger, where I cached snowshoes. Traverse along ridge was still snowy enough to be rather slow. Spikes were not used but could have been employed in places where neve' was firm. On return to Tigger, I descended the ridgeline directly and put flotation back on at treelike again. The boulders and snow fields made for a long day even in ideal conditions.

Info: Just a small update on top of the previous report: The road is trenched until the last switchback at 11600'. There, the road crosses a huge avy chute full of debris (very well packed) and instead of crossing it once again, the trench goes up directly on the ridge where it soon becomes rocky at ~ 11800 (perfect place to cache your snowshoes if you need to). We did not use snowshoes/spikes at all. Parking lot is full of snow and I did not want to take any chances and parked my Honda Accord right next to the parking entrance. That said, it is probably OK to park a capable car there (even like a Subie). Overall, long and tough route, took us 11.5 hours car-to-car and we finished at the dark at around 6:50. Haven't met a single person on the trail though.

Info: Started from 8,900' at the Frontier Ranch entrance. Earned every step going up Princeton after the recent snow storms. Ended up being two of us and a lone skier making tracks. Once we got to around 11,600-11,700' stashed our snowshoes and followed northern windblown slopes till we reached around 12,000' where the standard route connects. From there only microspikes were needed as we ascended to Tigger Peak's summit. Eventually the skier we had met turned around and we continued our progress up Tigger. Our strategy involved "connecting the dots" by boulder hopping to the top of Tigger while avoiding sections of unconsolidated snow. From there Princeton's summit was easily attainable by following sections of the standard route that was still exposed or by following the connecting ridge proper. Ended up being a full day effort, but was worth every step earned. Stunning sunset on the way back over Tigger before descending our snowshoe trail in the dark. 14.4 miles roundtrip. Elevation gain: ~5,500'.

Info: We didn't summit, so this is just conditions up to Tigger Peak. Was a bluebird day. We tried to take a 4wd F150 up the road, but only made it 0.25mi before turning back from snow. Instead we put on hiking boots + spikes to hike up the cat-tracked snowy road, which was easy going all the way up to the Princeton comms towers. Left our shoes and put on the boots+skis+skins to continue up the road from here. Often, the snow was windswept across the road such that traversing even in skins was annoying, requiring balance with poles to avoid side-slipping. We made it through the switchbacks like this on skins until the point where, in winter, route advises to summit Tigger rather than traversing the north slopes. We slogged it nearly all the way up tigger class 2+ scrambling in ski boots on mixed rock+ice+snow... not enough snow to boot pack except further south, which looked a bit too avy risky to ascend there. Needless to say this was brutal, and we decided about 200ft shy of Tigger to head back down. From there, the ridge to Princeton looked very windswept and the typical ski routes were fairly sparsely covered, although there were ski tracks. Anyway, we ripped the skins off, took a few steep, windblown turns on the ESE aspect of Tigger's ridge (not the couloir), a handful of good turns in there where sun had softened it a bit. Fairly easy descending all the way to the comms towers... once we were back on the cat tracked road, it was a rock-avoiding pizza roller coaster all the way down to the parking lot, except for one ~50ft stretch where we needed to remove skis and walk. Fun, alert descent.

Info: The road has been tracked out by a snowcat to the radio towers so no snowshoes were needed to that point. Beyond that it was packed powder, but we were able to get by with no snowshoes to the summit.

Info: Nearly summer conditions. There's a big tree down about 2 miles up the road, so not feasible to get to the towers, which was okay, I always start at the bottom to earn more beer.

Info: Packed down snow on the trail pretty much consistently from 11,900 ft to the summit, but not enough to necessarily need traction (might help though) and definitely not floatation. Gorgeous day today!

Info: Trail is fairly dry, though there's a couple of spots where snow is inconvenient, particularly getting to the ridge. Had my spikes and almost used them but didn't for no real good reason.
