We booked this tour as part of our honeymoon adventure along the west coast. It was the best decision! Both Dawn and Alexandra were super. The pace was steady with a few breaks to catch our breath. It was a great way to see a new city. We would definitely recommend this hike for people in good health (for reference, we are both in our late twenties and have been regularly going to the gym for the past six months) as it was a rather steep and narrow climb to the summit of Twin Peaks. Dawn and Alex kept us right on schedule with the timing, but did not rush us when we wanted to take photos at several points throughout. We would highly recommend this tour and can't wait to do another when we visit SF again!
