These are hiking trips, not walking trips, so you should have experience hiking in the mountains. We hike 4-7 hours per day with a comfortable lunch stop and other stops as needed. In order to enjoy the trip fully, you should be in good physical condition.
Our groups generally include many singles as well as couples. We take pride in making everyone feel comfortable.
Every group differs. Generally, the ages range from 35-65 with some in their 20's and 70's. It seems age makes little difference. As long as you are in good physical condition and enjoy meeting people of all ages, you'll enjoy the trip.
