Based off of previous reviews on this activity, I knew it was going to be fun. But boy did I underestimate my level of enjoyment. Waking up at 2am wasn't the easiest but it was worth the fatigue to see the sunrise from the top of Haleakala, above the clouds. I appreciated the company suggestions of where to stop for breakfast on the way down (Kula Lodge). The thrill of riding downhill at such high speeds was really exciting as well--and I am just a leisurely rider with no mountain biking experience. A few things that stuck out to me that I would want to mention to others: Wear warm clothes because at 10,000 feet elevation, it can be chilly. Dress in layers because you will get warm as you decrease in elevation. Wear gloves. The company provides vests, rain coats, backpacks and gloves if you'd like to borrow them. We chose not to take the gloves but regretted that decision as we came down the volcano. I would highly recommend this adventure as it truly was my favorite part of my Maui vacation.
