Getting to the water around Dunsmuir, Castella and McCloud

Fly fishing near Mount Shasta California: the geography in one paragraph

In practice this comes down to two rivers, plus a handful of small streams on the Trinity Divide. Mount Shasta City, Dunsmuir, Castella and the town of McCloud sit within about twenty five miles of each other. Interstate 5 runs north to south through the Sacramento canyon, with the river and the Union Pacific mainline squeezed into the same gap. Highway 89 runs east from the freeway at Mount Shasta City to the town of McCloud, and the road to the Lower McCloud leaves from there, running south past the reservoir and then dropping into the canyon on gravel. Driving from Dunsmuir to the town of McCloud takes roughly half an hour. Driving from the town of McCloud to the water at Ah Di Na takes about an hour more, most of it slow.

Access on the Upper Sacramento

Public access on the Sacramento is unusually good and unusually specific. Signed fishing access points appear at freeway exits and at bridges from the Cantara Loop north of Dunsmuir down to the Delta and Lakehead area at the head of Shasta Lake. Some are short walks from a lay by, others involve a genuine scramble down a bank. Dunsmuir itself gives street level access through the town park and neighbouring roads.

Two rules apply everywhere along this river. First, the railway is live, in constant use, and private property: crossing tracks is both dangerous and unlawful, and the underpasses and marked crossings exist for a reason. Second, access signs mark public entry to a river that is otherwise bordered by private land in many places. The detailed run through, north to south, is on the Dunsmuir access points page.

Access on the McCloud

The McCloud divides into three quite separate propositions. Above the reservoir, near the town of McCloud, the river runs past a series of waterfalls with easy roadside access and campgrounds beside it. The reservoir itself is a lake. Below the dam, the Lower McCloud runs into a steep canyon, and the practical public access is the Forest Service ground around Ah Di Na, reached by the graded dirt road out of McCloud, plus the walk in nature preserve immediately downstream, which limits the number of anglers on the water at any one time and applies its own fishing rules. Below the preserve the river runs through private holdings to Shasta Lake.

What that means in practice: the McCloud rewards planning and punishes improvisation. The road is slow, there is no fuel and no phone signal in the canyon, and turning around at four in the afternoon because you misjudged the walk is a long evening.

McCloud River camping and river access

Almost all of the camping on both rivers is public land, run by the Shasta Trinity National Forest or by California State Parks. Sites fill in July and August, and some operate on a first come basis while others take reservations. Opening dates depend on snow.

Fees, opening dates and reservation systems change from season to season, so check with the managing agency before relying on a site. Dispersed camping on national forest land is permitted in places and prohibited in others, and fire restrictions in late summer are strict and enforced.

What the canyon asks of you

• Poison oak is everywhere below about four thousand feet and is at its most potent in spring. Learn the leaf.
• Rattlesnakes use the same warm rock ledges anglers scramble over. Look before you place a hand.
• Black bears are common around the campgrounds. Food goes in the locker, not in the tent.
• Ticks are active from late winter through spring in the brush above both rivers.
• The wading is the real hazard. Round rock, strong current, and by August a coat of algae. Studded soles and a staff are ordinary equipment here, not precautions.

What to carry for a day of that is set out in the gear checklist, and two workable weekend structures are on the trip planning page.
