Top 3 Rainy Season Hikes: Mill Creek, CA

Rains summon salmon and slugs.

In any season, the 300-foot-tall redwoods lining Mill Creek in Jedediah Smith Redwoods State Park would be reason enough to hike this 5.4-mile (round-trip) trail—but autumn rains conjure a bonus. As precipitation plumps up Mill Creek, steelhead, coho, and chinook salmon take advantage of the deeper waters to swim upstream and spawn. Rain-lubricated leaves also create smooth sliding surfaces for neon-yellow banana slugs. Spot them among understory vines and maple leaves glowing brilliant red and yellow from October through December. Start at the western trailhead on Howland Hill Road and follow Mill Creek Trail as it bobs among the ferns on the stream’s west side. At 2.5 miles, you’ll hike right through a grove of fat, wrinkled old-growth redwoods before arriving at Stout Grove parking lot, your turnaround point.
