The 26.4 mi trail begins south of Grants Pass on Shoshone Lake Trail
and ends near Cave Falls in YNP's southwest corner. The trail climbs 650 ft in the first 2 mi to the first of 2 Continental Divide crossings. The trail dips to cross a stream flowing west to the Firehole River then again crosses the Divide at 3 mi. The Firehole Rive flows to the Gulf of Mexico via the Madison, Missouri, and the Mississippi rivers. The Bechler River drainage ahead of you flows west to the Pacific Ocean via the Bechler, Falls, Snake, and Columbia rivers.
The trail crosses Littles Fork and enters its lovely meadow at 5 mi, continues past Douglas Knob, and crosses the Gregg Fork at 7.2 miles. Thereafter, the short Twister Falls Trail (on right) leads to an overlook of the 55 ft falls (misplaced upstream on some maps). The trail continues along the Gregg 2 more miles, passes the Farris Fork Spur Trail (on left), crosses the Farris Fork, and reaches Three Rivers Junction at 9 miles.
Three Rivers is special! Here the Gregg, Farris, and Phillips forks join to form the Bechler River, named for Gustavus Bechler, chief topographer for the 1872 Hayden Survey. Little attention was paid to the park's southwest corner for the next 50 years. Then, in the face of attempts to dam the Bechler for irrigation, William Gregg explored the area and published articles describing its numerous waterfalls. There are 30 falls and cascades within 2 miles of Three Rivers, including 45-ft Ragged Falls, just up stream on the Farris Fork.
For 6.7 miles the trail follows the river through Bechler Canyon
, passing Three Rivers Cabin Trail (at 9.7 mi), Treasure Island (at 13.5), 45-ft Iris Falls (at 13.6), stunning, two-tiered Colonnade Falls (35 ft & 67 ft; at 14 mi), before entering Bechler Meadows. Along the way youll cross numerous streams and twice ford the Bechler. By early August the Upper Ford (at 11 mi) is usually knee-deep but the Lower Ford (at 12.6 mi) may be hip-deep (look for a shallow course on the downstream side).
The trail passes Bechler Meadows Cutoff Trail
(at 17.2 mi) and skirts the east side of this beautiful meadow, passes Mountain Ash Creek Trail
(at 20.4), and makes its final knee-to-hip-deep ford of the Bechler at Rocky Ford (at 21.4). It then follows the Bechler (past Bechler Cuttoff Trail at 23.4) past 15-ft Bechler Falls and the Falls River confluence (at 25.4), and reaches 250-ft wide & 20-ft high Cave Falls at 25.2 miles. No need to take the last 1.2 mi along the road.
