We did the midnight ATV ride (which was at 9pm as it was late July). Our guides Shane, Jeremiah, and Danny were clear, fun, and knowledgable (one of our guides is a science teacher during the year, so was very passionate about sharing Alaska's efforts to keep the land and waters healthy). As for the ride itself: A BLAST. We got side-by-sides because I didn't trust my driving, although I wish I got a single-ride ATV instead as it's more of a motorbike situation. However, being in the passengers side of a double-ATV allowed me to take amazing footage on my go-pro while taking in the sights (and staying fairly dust-free). There were 3 stops with lovely views. The sun was still pretty high when we ended around 11:00, and set during our 4-hour ride back to Denali. The shuttle bus driver, Becca, was also super friendly and knowledgable. Would recommend as this was a great way to take in the sights of Denali mountain!
