We really lucked out that it was mostly a clear day, so the view was amazing! Lots of people that we've talked to didn't have any view at all. The downside is we didn't anticipate that and all got really sunburned.
There are a series of stations along the way with snacks, water, oxygen and commemorative stamps they will burn into your walking sticks. You can also stay the night in one of the stations and get up early the next day to hike to the top for the sunrise. This probably would have been a better option than doing what we did and hiking it all in one day, but we had left Danielle and Avie back at the hotel and I didn't want to leave them overnight. Most people start hiking from the 5th station where a bus will drop you off. There are some that hike from all the way at the bottom! We met one guy along the trail that was doing that, yikes! It didn't take us long to get to the seventh station. There are only 10 so you're thinking to yourself, 'hey, this isn't bad, we'll be to the top in no time!'
