Ellicott’s BridgePublic (Eldorado NF)
Road access off Eleven Pines Road. Parking area, with the Hunter Trail leaving from the north side.
Hale’s Crossing · 6.75 mi hikePublic (Eldorado NF)
About 6.75 miles upstream of Ellicott’s Bridge on the Hunter Trail, 3 miles above the South Fork confluence. Remote, and the fishing reflects it.
Upper canyon to Hell Hole · 10 mi hikePublic (Eldorado NF)
The trail carries on about 10 miles from Ellicott’s Bridge to Hell Hole Reservoir. A sweeping canyon with steep cataracts; the upper reaches still carry debris from the 1964 Hell Hole Dam failure.
Buckeye Flat (Nevada Point)Public (Eldorado NF)
Volcanoville Road off Wentworth Springs Road (7.5 miles from Georgetown), then Woodpecker Road to the Nevada Point trailhead and down to Buckeye Flat.
South Fork RubiconPublic (Eldorado NF)
Around 2 miles of flat water with big pools and plenty of small rainbows near Loon and Shadow Lakes; a steadier middle section below the falls (about 116 adult rainbows per mile); busy near the Ice House Road forebay, better below it for rainbows and browns.

About this water

A rugged Sierra Wild Trout river with freestone character, high-country access questions and a short practical season once snow and runoff settle. It carries official designated-water status, but don't mistake that for an easy roadside fishery — high-country access and a short season are the reality.
