It's hard to believe there is a way down to the San Juan River in this area. But back in 1893, Henry Honaker constructed a trail as a supply route for gold prospectors. The gold mining didn't pan out (pun intended) and legend has it that Honaker only collected enough gold to make a wedding ring for his wife.
Running up the Honaker Trail is a classic San Juan River rafting activity, though many groups will turn around at Horn Point after about 1.3 miles, when the trail reaches a rock outcrop almost directly above the starting point below, rather than climb the entire 1200 ft.
From the parking area on the rim above, the descent and climb back out aren't difficult per se, but they do follow steady grades. However, your effort is rewarded constantly by fantastic views and an often-beguiling interaction of light and water.
