At a Glance

  • Views into the North Fork Kings River canyon from the reservoir rim
  • Mixed conifer forest with minimal elevation gain for the views gained
  • Less-visited alternative to the more popular Dinkey Lakes and Kaiser routes
  • Year-round access when the access road is clear

Overview

The Wishon Rim Trail accesses a quieter section of Sierra National Forest in the southern portion of the forest near the Dinkey Creek area, following the rim above Wishon Reservoir with views into the North Fork Kings River canyon. The trail is less publicized than the forest's headline routes (Kaiser Peak, Dinkey Lakes, Rancheria Falls) and sees a corresponding fraction of the visitor traffic, making it a reliable choice for hikers who want the Sierra Nevada conifer forest experience without the crowds.

The 5-mile round trip gains 800 feet on a trail that follows the natural topography of the rim, with the reservoir visible below and the canyon stretching below the rim edge. The mixed conifer forest through which the trail moves is typical of the 5,000-6,000 foot elevation band in the Sierra: white fir, incense cedar, ponderosa pine, and black oak in the lower reaches transitioning to red fir higher up.

No permit or fee is required for this hike. The access road from the Dinkey Creek Road network is unpaved for the final approach. Before visiting, check current conditions for road access and any seasonal restrictions. Leave No Trace principles apply; the rim edge in places has significant drop-offs and staying on the established trail is both safer and better for the surrounding vegetation.

The Route

Miles 0 to 2: Forest Approach and Rim

From the trailhead near the reservoir, the trail climbs into the mixed conifer forest and begins following the rim above the water. The reservoir comes into view within the first mile. The North Fork Kings River canyon is visible below the rim edge in several places. The forest is open enough to allow views while providing good shade.

Miles 2 to 2.5: Canyon Viewpoint

At roughly mile 2.5, the trail reaches a high point with the best views of the canyon stretching south and east. The Kings River canyon here drops significantly, providing a sense of the elevation range that characterizes the southern Sierra. This is the natural turnaround for most hikers. Return the same route.

When to Visit

May through October. The access road to the trailhead opens earlier than the upper wilderness routes, making this a practical early-season option. Summer is pleasant at this elevation (5,000-6,000 feet) without the extreme heat of the lower Kings River canyon. Fall color in the oaks along the lower rim section is good in October.

What to Bring

  • Many hikers carry 1.5 liters of water for this length and elevation gain; individual needs vary.
  • Layers: morning temperatures at the reservoir rim are typically cooler than the valley floor.
  • Sturdy footwear with ankle support for the rocky rim sections.

Practical Details

No permit or fee as of 2026. No restrooms at the trailhead. Day hike; no overnight camping facilities at the rim. Dogs allowed on leash; keep dogs away from the rim edge.

Getting There

From Shaver Lake on Highway 168, drive south on Dinkey Creek Road approximately 20 miles toward Wishon Reservoir. Turn right on the signed road toward the reservoir. The final mile or two to the trailhead is unpaved. A high-clearance vehicle is helpful. From Fresno, take Highway 168 northeast to Shaver Lake, then south on Dinkey Creek Road. Total drive from Fresno is approximately 1.5-2 hours.

Trailhead Parking

Trailhead near Wishon Reservoir, off Dinkey Creek Road south of Shaver Lake. Gravel pullout for approximately 10 vehicles. No fee as of 2026.

Frequently Asked Questions

What is Wishon Reservoir?
Wishon Reservoir is a small reservoir on the North Fork of the Kings River in Sierra National Forest, created by Wishon Dam. The dam is operated by Pacific Gas and Electric. The reservoir and surrounding public lands are managed cooperatively between PG&E and the USFS.
Is this trail appropriate for beginners?
The 800-foot gain over 5 miles is mild and the trail is well-defined, making it accessible for hikers with basic fitness. The lack of crowds and generally good trail conditions make it a reasonable option for newer hikers building Sierra Nevada trail experience.
Are there views of the water from the Wishon Rim Trail?
Yes. The reservoir is visible from several points along the rim trail. The views into the North Fork Kings River canyon below are the primary visual attraction.
How crowded is the Wishon area compared to the Dinkey Lakes?
Wishon Reservoir and the surrounding trails receive far fewer visitors than the Dinkey Lakes and Huntington Lake areas. This is one of the quieter corners of Sierra National Forest despite its relative proximity to the main recreation hubs.
Can I fish at Wishon Reservoir?
Fishing is possible at the reservoir. Check with the USFS and California Department of Fish and Wildlife for current access rules and fishing regulations specific to this reservoir, as PG&E operational needs can affect access.
