Crescent City is a compact, scenic coastal town (population ~6–7K) that feels like a livable, walkable base for multi-week assignments — think oceanfront views, Battery Point Lighthouse, beaches and tide pools, plus immediate access to towering redwoods and trails in Redwood National & State Parks and Jedediah Smith Redwoods State Park.
For quick variety, Brookings, OR — a lively coastal town with more dining and beach options — is only about 26 miles north, and Arcata (home to Cal Poly Humboldt and a bigger restaurant/arts scene) is roughly 71–72 miles away, so you have easy day-trip choices if you want more nightlife, shopping, or college-town energy during a several-week stay.
