💡 Pro Tip: Richardson Grove is the first old-growth redwood forest you encounter heading north on Highway 101 — park and walk among the groves for an unforgettable first impression. The South Fork Eel River offers excellent swimming in summer (water levels drop significantly by July–August). Book campsites early for summer — sleeping beneath ancient redwoods is a bucket-list experience. Note that Highway 101 narrows through the park and cannot accommodate oversized vehicles — check Caltrans advisories for large RVs.
