Access and camping

Dunsmuir fly fishing access points, north to south

Thirty eight miles of trout river run beside a freeway, a railway and a string of small towns, and the state has signed public access to it at intervals for the whole length. Very few trout rivers in the western United States are this easy to reach, and knowing the character of each stretch turns that into an advantage.

In short

Access runs from the Cantara Loop north of Dunsmuir down to the Delta and Lakehead area at the head of Shasta Lake, with signed public entry at freeway exits, bridges and town streets. Upper reaches are colder and smaller, lower reaches are bigger and warmer. Never cross or walk the railway: it is live, private and dangerous.

The shape of the river

The Upper Sacramento begins at Box Canyon Dam below Lake Siskiyou near Mount Shasta City and runs south for roughly 38 miles into Shasta Lake. It gathers water the whole way, so the river at the top is a small, cold, brushy stream and the river at the bottom is a substantial freestone river that warms markedly in summer.

That gradient is the most useful planning fact on this page. In hot weather, work the upper reaches early. In cold weather, or early and late in the season, the lower canyon is often several degrees warmer and correspondingly more productive.

Signage, parking and permitted entry change over time, and some points that were open one season are closed for construction or safety the next. The state publishes current public access information for the river, and the towns along it post local notices. Treat the table above as a description of the corridor rather than a guarantee about any single lay by.

The railway rule

A mainline railway runs the length of this canyon, often within a few metres of the water, and it carries freight day and night. The track and the ballast beside it are private property, and walking, crossing or fishing from them is both unlawful and genuinely dangerous. Modern locomotives are quiet and the canyon walls confuse the sound.

Use the underpasses and the marked crossings. Where there is no legal way from the road to the water, there is no access at that point, and there is another one a few minutes down the highway.

Sharing a narrow river

  • Look before you park. If a car is already at the lay by, someone is in that stretch. Drive on.
  • Enter downstream of another angler, never above them, and leave a generous gap.
  • Walk on the bank, not through the river, when passing water someone else is fishing.
  • Respect private land. Access points are specific for a reason. Fenced ground on either side of them is not public.

Building a day around access

The practical way to use this corridor is to plan three stops rather than one. Fish the first at dawn, move by mid morning, and keep the third in reserve for the evening. Because everything is close to the freeway, moving costs minutes rather than hours, which is a luxury this river offers and the McCloud does not.
