Overview

Lake Pillsbury is the largest lake in Mendocino National Forest, a 2,040-acre reservoir surrounded by mixed oak woodland and gray pine forest in the southern portion of the forest. The 6-mile loop circles the lake through characteristic inner Coast Range terrain, with consistent water views and multiple fishing access points. This is the most family-accessible hike in the Mendocino area, combining gentle terrain with the lake as a consistent destination.

No permit required.

The Route

Miles 0 to 2.0: North and west shores. From the campground parking area, the trail heads counterclockwise along the north shore through blue oak, gray pine, and manzanita. The lake is visible throughout. The character is dry and sunlit on the open hillside sections above the water.

Miles 2.0 to 4.0: South shore. The southern end of the lake has the most secluded sections, away from the main campground. The forest becomes denser here with canyon live oak and some Douglas fir on cooler north-facing sections. Bank fishing access is excellent.

Miles 4.0 to 6.0: East shore return. The east shore returns toward the campground through the more developed recreation area. The boat launch and picnic area are visible across the water.

When to Hike

April through June for wildflowers on the hillside sections. July and August for lake swimming after hiking. September and October for bass fishing and fall color in the oaks.

What to Bring

Many hikers carry 1.5 liters of water. Water and flush restrooms are available at the campground. Fishing gear recommended. Sun protection on the open south-facing hillside sections.

Frequently Asked Questions

How is fishing at Lake Pillsbury?
Lake Pillsbury is one of the better fishing lakes in the Coast Range, holding largemouth bass, smallmouth bass, channel catfish, and rainbow trout. The lake is large enough to support boating, and the trail provides bank fishing access throughout the loop. Summer and fall are the best bass fishing windows; trout fishing is better in spring when water temperatures are cooler. A California fishing license is required (as of 2026).
Can I bring a kayak to Lake Pillsbury?
Yes. Lake Pillsbury has a boat launch at the main recreation area, accessible to kayaks, canoes, and motorized boats. The lake is open to all types of watercraft with a valid Coast Guard-required safety equipment. Paddling the lake while doing portions of the loop trail on foot makes for an excellent full-day experience.
Is Lake Pillsbury Loop popular?
Lake Pillsbury is one of the more accessible destinations in Mendocino National Forest and the loop trail is the most commonly hiked route in this part of the forest. Compared to typical California lake destinations, however, Pillsbury remains uncrowded. Summer weekends bring RVs and boaters to the campground, but the trail away from the main campground area is generally quiet.
