At a Glance

  • Year-round river access with multiple swimming holes in summer
  • Giant sequoia groves accessible from the upper trail
  • Shaded canyon walking with consistent water views
  • One of the most accessible trails in Sequoia National Forest from the San Joaquin Valley

Overview

The North Fork of the Tule River drains the western slopes of Sequoia National Forest through a canyon that climbs from oak woodland to giant sequoia forest in the space of a few miles. The trail following this drainage is the most accessible long hike in the forest from the San Joaquin Valley side, starting just 28 miles east of Porterville on State Route 190 and climbing through progressively cooler and more forested terrain.

At 6 miles round trip with only 800 feet of elevation gain, the trail is gentle enough for most hikers while covering enough distance to sample a meaningful cross-section of the canyon ecosystem. The river is rarely out of sight or earshot for the full length of the trail. In summer, the swimming holes are a draw in their own right, and many hikers treat this as a river walk as much as a summit trail.

The trail also serves as an entry corridor into the higher reaches of the forest. Beyond the 3-mile mark, the canyon opens into broader forest and the first signs of the giant sequoia belt appear. Many hikers treat the Tule River Trail as an appetizer for the upper forest, then drive up State Route 190 to explore the giant sequoia groves closer to Quaking Aspen. For information on responsible visiting practices along river corridors, see our Leave No Trace guide.

The Route

Miles 0 to 1.0: From the Doyle Springs trailhead, the trail descends briefly to the river's edge before settling into a north-trending course along the North Fork. The first mile stays close to the water, crossing several small tributaries on log bridges or rock hops. The vegetation here is a mix of incense cedar, white alder, and canyon live oak.

Miles 1.0 to 2.0: The canyon narrows slightly and the gradient eases. Several broad gravel bars and deep pools appear along this section, offering the best swimming and wading spots on the trail. The canyon walls rise several hundred feet on both sides, and the forest thickens. A few campsites used for dispersed overnight stays are visible set back from the river.

Miles 2.0 to 3.0: The trail climbs more noticeably as it approaches the upper canyon. The first giant sequoias appear scattered among the mixed conifer forest on the north-facing slopes. The river is audible but the trail pulls slightly away from the bank through this section. The turnaround point at 3 miles is not formally marked; most hikers reverse at a natural clearing near a larger tributary junction.

The Return: The route follows the same path back. The gradual descent makes the return faster and easier than the ascent.

When to Visit

The Tule River Trail is accessible for most of the year due to its low starting elevation. Spring (April-May) brings high water and spectacular wildflower displays in the oak zone near the trailhead, but the river can be too high and fast for safe wading. Summer (June through September) is the most popular season, with reliable swimming conditions and shaded canyon walking that stays comfortable even on hot valley days.

Fall is underrated: the canyon maples and alders turn yellow and orange in October, the crowds disappear after Labor Day, and the river conditions are calm. Winter visits are possible in mild years but the trail can be icy in shaded sections.

Check current conditions via the Forest Service's conditions and alerts resources before an early-season visit when water levels are uncertain.

What to Bring

Many hikers carry 1.5 to 2 liters of water for this trail, though river water is available throughout for those with a filter. Individual needs vary. For summer swims, consider water shoes for rocky creek crossings and pool entries.

Consider bringing:

  • Water filter or purification tablets if planning to drink from the river
  • Sandals or water shoes for swimming access
  • Sun protection for exposed sections in the lower canyon
  • Snacks for the river pools, which invite lingering

Practical Details

No permit is required for day hiking. Overnight dispersed camping is allowed in the corridor with a free campfire permit for any open fire. The vault toilet at the trailhead serves the parking area. Dogs are welcome on leash.

The America the Beautiful pass may be required at the day-use parking fee station; verify current requirements before visiting. Veterans and military families should check eligibility for free passes at our veteran benefits page.

Getting There

From Porterville, take State Route 190 east approximately 28 miles to the Doyle Springs area. The trailhead is signed on the left (north) side of the highway. The parking area is paved and accommodates passenger vehicles. Cell service ends before the trailhead; download maps offline before departing. The drive takes approximately 40 minutes from Porterville.

Frequently Asked Questions

Can I swim in the Tule River?
Yes, the North Fork of the Tule River has several swimming holes along the trail corridor in summer. Water levels and conditions vary by season. The river runs high and fast in spring snowmelt (April-May) and drops to calm pools by midsummer. Always assess water conditions before entering.
Are there giant sequoias on this trail?
The upper sections of the trail, beyond the 2-mile mark, enter old-growth forest that includes scattered giant sequoias. The groves are not as dense as those in Sequoia National Park, but individual old-growth specimens appear along the route.
Is the Tule River Trail suitable for beginners?
Yes. The gradual elevation gain and maintained trail surface make this a good choice for beginning hikers or those with limited experience. The 3-mile one-way distance can be shortened by turning around at any point.
Does the Tule River Trail flood in spring?
The trail follows the river closely in several sections and can be affected by high water during peak snowmelt in April and May. Some sections may require wading in high-water years. Check conditions before an early-season visit.
