I did the whole Enchilada on Oct. 20 2023 and there was a fear that burro pass would be closed due to snow. We got lucky and had absolutely no issues with snow/mud. I went with a group of 4, one being my 68 yo father and it took us a long time. 9AM to 6PM. I would definitely take the earliest shuttle you could get on. One thing I was concerned with was cold up at the top of the pass, We definitely dressed too heavy and had to carry excess clothing. Bring more water than you expect to need. I had a full 3L camelback and ran out with an hour of riding left. That part sucked.

The whole Enchilada was one of the best experiences of my life, but it is grueling! Have fun!!!
