I wandered around Rampart Ridge three years ago and started up the path to the top of Alta Mountain, but started feeling ill and turned back. I promised myself I'd come back and go all the way, and I finally kept that promise yesterday.
I should note that Harvey Manning's description and sketch map is deceptive. He makes it seem like you go straight at the Lila Lakes/Rampart Lakes junction. In fact, this intersection is a T, the only real options are left (to Rampart Lakes) or right (to Lila AND Alta Mountain). Straight ahead is just a brief path to nowhere, tellingly blocked off by branches. To head up Alta Mtn, the most spectacular choice of the three in my opinion, go right toward Lila Lakes. The trail climbs for a little while, staying on top of the ridge. Immediately before it drops off the top of the ridge to the right, there is a junction with a trail in some heather to the left. Turn left there if Alta Mtn is your destination. It pretty much stays on top of the ridge the whole way, an amazing tightrope act, with several false summits. It's not that hard, but watch your step -- one bad slip and you're toast. If you've dropped off the top of the ridge by more than a few feet, you've missed the junction.
It has been so hot and dry lately that even the Rachel Lake trail has only a couple small muddy spots. There were some biting flies and some skeeters, but not too bad. I didn't have to bust out the DEET, so I feel like a flag is not merited. I propose this be the test. If you never use DEET because it will kill the planet or give you cancer or some other silly reason, try to imagine when you WOULD put on DEET if you weren't so silly. All in favor type ""Aye.""
