The only bad part of the day was having to wake up at 1:45 a.m. in order to be picked up at 2:15. Other than that, the trip was terrific! We were in our lobby at 2:10 a.m, and the driver was already there waiting for us, and we were the first pickup. Our van was spacious and the driver was friendly. We got to the office location at 3:30 a.m. where a light continental breakfast was served. We left the office and arrived to the top of the mountain at 5:15 a.m. As other reviewers mentioned, dress warmly! It was about 40 degrees at the top of the mountain, and we took the advice of dressing in layers (including sweatpants and gloves) - and we were warm. There was a park ranger at the top of the mountain and he was very protective of the land - it was easy to see how passionate he was about the environment and not straying from the paths. The sunrise was beautiful - the top of the mountain was above the clouds, and it was amazing to see the sunrise. After the sunrise, our driver took us to two other stops at the top of the mountain while giving a brief history of each. After the second stop, we drove down to 6,500 feet and met our guide for the biking portion. Our driver left, and our tour was led by Zep (who rode with us) and a new driver (whose name we cannot remember, but he was also nice). Zep was fantastic - as one of us hadn't biked in over 10 years, we had to disclose this - and Zep was patient and focused on safety. He made sure even the least experienced riders were capable of making to the bottom (and stressed that we could stop anytime and ride in the van instead). We made 2 stops while biking to the bottom - one for pictures and the second for a late breakfast. The ride down was almost entirely downhill and beautiful. We biked at speeds of 10 mph-23 mph (you are not allowed to participate if you go slower than 10 mph, and average speeds are 15-20 mph). The ride was very controlled by the leader of the group. The van follows the bikers in case anyone needs to stop. Our only suggestions are to dress in layers, be ready to wake up early, and bring a bottle of water and some snacks. There was a gap of about 6 hours from the time we left the office to the time that we got to the late breakfast stop.
