The answer from Crystal Mountain Resort:
We do not provide lift-served mountain biking, but some trails are open to mountain bikes via muscle-power. Some trails are closed to bikes entirely, like the Pacific Crest Trail and some spur trails that lead up to the PCT.
Bicycles and unicycles are not uploaded on the Gondola.

Good to know, but I wish I had read this thread before my trip:
In August 2015 I rode the lift with the muni twice in Whistler. In the line and at the bottom no one said anything (actually on the second ride I got a thumbs up from 2 different lift personnel), but while unloading at the top they asked me if I was going to ride down the trails and I answered, “Planning on trying it”. They seemed to not think it was allowed but were unsure and so just told me to stay out of the way of bikers and told me it was dangerous because of the high-speed bikers but then didn’t prevent me from riding off… (as an experienced downhill mountain biker I pretty much know what to expect).
I did the beginner track down and ended up passing about the same number of bikers as passed me, which surprised me a lot (as I ride way faster on the bike). Everyone was friendly and most people were totally shocked and impressed.
Almost all of the mountain bike parks in Germany/Italy/Austria that I have tried have allowed unicycles. Samerberg in southern Germany is very uni friendly and even hosts an annual muni downhill.
I have never tried during the ski season. With the new fat mountain bikes it seems like ski areas will probably need an official winter policy soon too.
Purgatory in Durango, CO was great
The folks at Purgatory in Durango, CO couldn’t have been more supportive this summer. In fact the only person who acted like it wasn’t a regular occurrence was the guy at the top of the lift, who genuinely believed at first that half my bke hadn’t made it up. I couldn’t figure out what he meant when he asked, with genuine concern “what’s going on back there??” I had to assure him that’s all the bke I had loaded at the bottom. Hikers were happy to share the trail and other cyclists gave me plenty of room.
Another update: Crested Butte, Colorado not only allows unicycles, the lift personnel were supportive and interested. I did 2 runs in August 2016: the black run “Avery” was pretty awesome and I was able to ride all but 2 really rocky sections (a few UPDs and reattempts necessary). I tried the double-diamond track “Psycho Rocks”, and while I probably was able to ride over 60% total, I had to walk most of the really hard drops and steeps.
They said they had never seen a unicycle there before.
Whiteface Mountain in the Adirondacks has lift access for mountain biking and while I was there I heard that a couple unicyclists had rode it (anyone on here?).
Bagnères de Luchon (France)
here is a strava trail (very difficult but plenty of other trails)

Puy St. Vincent in France takes mountain bikes and mountain scooters. https://www.theguardian.com/travel/2015/feb/28/great-little-ski-resorts-puy-saint-vincent-france-alps They have graded runs - same grades as ski runs.
My aim is to take my uni up next year.
I am sure they will take me…
Ski Apache, Ruidoso, New Mexico
Great day riding the ski resort at Ski Apache in Ruidoso, NM. Everyone was really supportive. Including, I suppose, the supervisor who didn’t know I could hear and told one of the employees “He signed a waiver, let him do what he wants.”
You should add that one on the “Quote of the Day from Non-Riders” thread. 
But really, having signed the waiver is for the park’s benefit, so they don’t have to be paranoid (or otherwise not let you ride). They want happy customers, and this way they can relax also, and let you have your fun. Just like unicycle convention hosts have to do, to make those events palatable to host.
Just to update for the Lake Tahoe area:
I ran into a problem at Stratton Ski Resort yesterday in Vermont and they wouldn’t let me ride. Do you or does anyone have any blanket letters I can use to convince them to allow mountain unicycles? I have the managers email and want to send a nice letter with important info including maybe a couple links to some good muni videos so any help would be appreciated. Thanks!
For what it’s worth, here’s an old (2011) but friendly reply from the Whistler Mountain Bike Park manager at the time, when I’d followed up after the same thing occurred in Whistler:
Sorry, I don’t have anything official.
At Unicon unicyclists were allowed at Giant’s Ridge Recreation Area in Minnesota.
In Europe I have had few problems but Europe has a different stance on liability.
I think the idea with links is good. Maybe emphasize that you won’t be on the jump line and know not to stop at blind spots after a jump and such. I would also argue if they don’t prohibit kids then you are probably faster and stop less than many 6-8 yo kids do when they are learning.
Might also be nice to have (maybe here?) a list of resorts where resorts are known to have ridden. This list is super old (2011), but from a past time when this happened:
Northstar at Tahoe
Lutsen Ski Resort, Minnesota
Snowqualmie Summit (1998-2002)
Camp Fortune (Ottawa)
Gunstock (Gilford, NH)
Copper Mountain. CO
Telluride, CO
Big Sky MT
Beaver Creek, CO
Breckenridge, CO
Attitash (NH)
Snowshoe Mountain, WV
Wintergreen, VA
Mt Hood Ski Bowl, OR
Whakapapa Ski Area, Mt Ruepehu, NZ
Marble Mountain (Western Newfoundland)
Ray’s Indoor Bike Park (USA)
Dundret in Gellivare in Sweden
Snow World in Landgraaf, The Netherlands (Indoor Ski Resort)
Haha just realized that I started this thread way back in 2005, should have checked!
I have ridden my Flansberrium 29+ at Bryce Mountain Bike Park in VA. The employees and lift operators were all very encouraging and nobody complained about me.
But I’m not sure if unicycles are officially allowed.
