There's a lot more to the Grand Canyon than can be seen from the top. Walk seven miles down and you arrive at the river that created the spectacular chasm, the Colorado. Stay overnight at a rustic lodge at the bottom, and you begin to get a different sense of scale about the place.
Then it's on to the main attraction. The group stays on the South Rim in Grand Canyon National Park before heading down the South Kaibab Trail. The night is spent at Phantom Ranch, which features cabins and a dormitory-style lodge reachable only on foot or by mule, before a nine-mile hike back to the top the next day.
Selected trips in this series are led by veteran guide Andre Potochnik, who has a doctorate in geology and has led river trips in the canyon for more than four decades.
When: Trips depart April 10 and 25, May 1 and 12, Sept. 10, 15 and 22 and Oct. 6, 11 and 29. (Check the website for trips guided by Potochnik.)
