Highly recommended! We booked for 9:30 AM, checked in at 9:00 AM, and gathered for group departure at 9:20 AM. The entire tour was on foot and lasted about 1 hour and 15 minutes. I want to highly praise our guide, Colin B. He was extremely friendly, provided commentary throughout the entire tour, and proactively helped us take photos of ourselves and the scenery. He didn't explicitly ask for a tip, but he certainly deserved one.
