I did this yesterday and it was very enjoyable. First the parking was super packed at 9:30am already. I did I two round in the lots then I was trying to find on the road and there was a nice guy pointing at his car that he’s leaving! Thank you sir!!

Anyway if I didn’t know about the trail, I would be sure to get lost. So you should check where the trail sprit. And like everyone said here it’s not 12 miles. It’s more like 16miles. (My phone die on the way coming down, so there is no accuracy but I was glad that I made it to parking lot) Last couple of miles going up was tough. I kept stopping and looking up when this uphill/switchback end.

I finished my entire 1.5l water going up so make sure you have enough water and snack to refill.
Cosmic cafe save my life on summit.

Going down from summit was confusing. There is no sign going down. I had to walk around the parking lot and observatory gate. There is a trail in the middle of parking lot. But again no sign!

Downhill was easy but sandy and easy to slide so be careful. At the white creek ? Trail sprit and I had no strength to go uphill at the beginning of trail, so I went right to chantry flat for another 3 miles.

Going up and down, there is plenty of gnat and mosquitoes. Be sure to spray bug spray everywhere and I saw a sign that there is a bear so maybe bring a bear bell.

I saw a deer family running by me and looking at me so it was a delightful moment and that it self made my day.
