Our guide Alex was great. He was very patient with us. The crater and the lake was absolutely beautiful. I took many pictures on the way down. It was actually very cool, almost cold as well as windy on the rim but it quickly warmed up on the way down and I needed to take off a couple layers. They way back up was steep and difficult so I took the Quilotola Uber, a mule for $10, well worth the expense. Your shoes and pants will get full of dust from the trail. I would definitely recommend this tour.
