Rhododendron Trail and Foothill Trail Loop

Overview

This loop stitches together some of Prairie Creek Redwoods State Park’s most varied forest: quiet upland redwood slopes on the Rhododendron Trail and grand, creek-cut groves on Brown Creek and Foothill. Plan on roughly 9.0 miles total. It’s a real hike—expect roots, short steeps, and occasional obstacles—but the payoff is a crowd-thinning first half and classic giants near the end.

Route Snapshot

Most hikers start at Prairie Creek Visitor Center, take a short piece of Cathedral Trees Trail, then commit to the Rhododendron Trail across the hillside. After crossing Cal Barrel Road, continue to the junction with Brown Creek Trail and descend through a lush redwood glen. Turn left on the Foothill Trail, cross the long high bridge over Corkscrew Creek, pass Big Tree and Rotary Grove, and finish the last short segment back to the visitor center.

What You’ll See and Feel

• Rhododendron Trail: narrow tread contouring a shaded slope with rhododendron thickets, classic redwoods, and a memorable hollow “chimney” redwood along the way. Scenery opens up after Cal Barrel Road with larger trees and livelier creeks in winter/spring.
• Brown Creek: one of the loop’s highlights—an intimate redwood glen where the trees steadily size up.
• Foothill: initially closer to the road with smaller trees, then dramatically better as it dips into bigger, darker ravines. The bridge over Corkscrew Creek is a standout. The finale at Big Tree is textbook North Coast redwoods—about 1,500 years old, 286 feet tall, with a 74.5-foot circumference.

Keep an eye out for seasonal rhododendron blooms (late spring into early summer), carpets of false lily-of-the-valley, bright-blue clintonia berries, ghost pipes, banana slugs, and bigleaf maples tracing the drainages.

Conditions and Reality Check

Rhododendron is beautiful but can be overgrown and rooty, with steep sidehill cuts. Recent reports mention big downed trunks and even a broken bridge—detours may be necessary. Wayfinding is generally straightforward, but pay attention at road crossings. Early Foothill segments can carry highway noise before the trail dives into better forest.

Best Time to Hike

Year-round. For flowers and flowing creeks, late spring through early summer is prime; winter and early spring bring the best creek soundtrack and very few people. Start early to enjoy the quiet Rhododendron stretch and hit Big Tree before mid-day visitors. Soft, even light under the canopy makes photography forgiving all day; low-angle morning light adds atmosphere in the ravines.

Tips

• Dogs aren’t allowed on these trails.
• Waterproof footwear helps on slick roots and bridges; long sleeves make rhodie brush more pleasant.
• If conditions are rough on Rhododendron, you can bail to the road and drop back to the flats via signed connectors rather than re-earning the obstacles.
• Want a mellower sampler? Stay on the flats with Karl Knapp (Prairie Creek) and Foothill for a short loop among giants.
