The Lost Coast Trail is a 25-mile point-to-point coastal route along the longest stretch of undeveloped coastline in the contiguous United States, in Northern California's King Range. The mountains here rise straight out of the Pacific, on terrain too rugged for Highway 1. You'll spend days walking beaches of coarse black sand and wave-smoothed stones, timing your passage with the tides, watching elephant seals haul out on the shore, and camping to the sound of crashing waves. The skills it tests are different from a mountain trail's: reading tide charts, navigating boulder fields, and grinding through miles of energy-sapping sand with a full pack. It's best for backpackers who want solitude and ocean wilderness and don't mind trading alpine scenery for tide-dependent logistics.
Wilderness permits are required year-round for overnight camping and must be reserved through Recreation.gov on a 90-day rolling window (reservations open at 7:00 AM PST exactly 90 days before your start date). Daily quotas are strictly enforced: 60 backpackers per day from May 15-September 15, dropping to 30 per day the rest of the year. Maximum group size is 5 people. No walk-up permits are available.
Hard-sided bear canisters are mandatory; bear bags and hangs are explicitly prohibited. Black bears are active at several campsites, particularly Big Flat and Miller Flat. Before purchasing your permit, verify passable tide windows for your dates, because the BLM will not issue refunds if you book dates with impassable tides.
A California Campfire Permit is required for camp stoves and fires. Campfires are prohibited July through October and are never allowed outside of existing fire rings. During fire season restrictions (typically summer), only gas stoves with a valid permit are allowed, and open fires remain banned on the beach even in developed rings. Several wildfires have been started by camp stoves in recent years.
Camping is prohibited at Black Sands Beach/Shelter Cove and at Telegraph Creek (camping allowed north of Telegraph Creek only). Stay at least 500 feet from the Mattole Campground if beach camping near the trailhead.
Late May through early October has the most reliable weather, with temperatures in the 60s-70s during the day and 50s at night. July-September bring heavy fog, so expect limited visibility and damp conditions even without rain. Shoulder seasons (mid-March to May 15 and September 16 through October) offer excellent hiking with lower permit competition, but the weather becomes more unpredictable.
Winter (November-April) turns the Lost Coast into one of the wettest places in California, with 100+ inches of annual rainfall concentrated in these months. Stream crossings that are ankle-deep wades in summer become dangerous torrents. High surf adds another hazard, and the road into Shelter Cove can ice over for days. Daily permit quotas drop to 30 in winter, so permits are easier to get if you're prepared for the conditions. Winter backpackers should have experience with storm camping and high-risk stream crossings.
Water is abundant from numerous coastal creeks, though all sources require treatment. Streams flow year-round on the northern two-thirds of the trail. Gitchell Creek is the last major water source before the final push to Black Sands Beach, so fill all capacity there. Some smaller streams can be spotted by breaks in the bluffs, but plan your camps around the known creeks: Cooskie, Big Flat, Miller, Buck, and Gitchell are the most reliable.
This is a point-to-point trail with no resupply options. The Shelter Cove General Store (7272 Shelter Cove Road) near Black Sands Beach is fully stocked with groceries, beer, wine, fresh produce, and camping supplies, plus bear canister rentals. Petrolia General Store, 6 miles from Mattole Beach, carries basic supplies and also rents bear canisters (cash only). Eureka and Garberville are the nearest full-service towns for major pre-trip provisioning.
Tide timing is non-negotiable. Three sections of trail become deadly at high tide with no escape routes, only vertical bedrock walls between ocean and cliff:
Always enter impassable zones on a receding tide, ideally starting 30-60 minutes before low tide. Plan on 1 mph through the boulder fields. Check NOAA tide predictions for each day of your trip before finalizing your itinerary. Tide windows dictate your camp locations, not your preferred mileage.
Northern Pacific rattlesnakes frequent driftwood and high grass, often crawling alongside logs. Step over logs carefully rather than placing hands first. Ticks carrying Lyme disease are common in brushy sections, particularly north of Little Jackass Creek, so wear long pants and do thorough body checks. Poison oak is abundant; stick to the beach when possible.
Black bears are habituated to backpackers and regularly patrol the Big Flat, Miller Flat, and Cooskie Creek camps. Store canisters 100+ feet from camp. Recent sightings include bold bears investigating camps even during daylight.
The energy cost of hiking on sand and loose cobbles is often underestimated. Expect to travel at 50% of your normal trail pace. The uneven ground and constant ankle adjustment take a toll, and trekking poles are highly recommended. The final 10-mile beach walk from Miller Flat to Black Sands involves the hardest beach boulder navigation of the entire route.
The trail runs north-to-south between Mattole Beach and Black Sands Beach near Shelter Cove. Most hikers start at Mattole and hike south with the prevailing winds at their backs. The drive between trailheads takes 3 hours on winding, narrow mountain roads.
Mattole Trailhead: From US-101, take the Ferndale exit and follow signs to Petrolia. One mile past Petrolia, turn right on Lighthouse Road for 5 miles to Mattole Recreation Site (42 miles total, allow 1.5 hours from 101). The roads are paved and fine for passenger cars except during severe winter storms. First-come camping and parking are available at the trailhead.
Black Sands Beach Trailhead (Shelter Cove): From Redway on US-101, take Briceland-Shelter Cove Road west for 23 miles. High clearance is not required, but the roads are steep and winding. Not recommended for RVs or long trailers. Parking at the beach is free and plentiful.
Airports: Nearest is Arcata-Eureka Airport (ACV), 3 hours to Mattole. San Francisco International (SFO) is 4.5 hours south. You'll need a rental car from either airport.
Shuttles: Lost Coast Adventure Tours (707-986-9895) and Lost Coast Shuttle (707-986-7437) run daily service between trailheads for $95/person. Shuttles run southbound only (Black Sands to Mattole drop-off). Book well in advance. Some hikers arrange key swaps with northbound parties, though vehicle break-ins have been reported.
Most hikers finish the trail in 3 days (common camps: Sea Lion Gulch, Spanish Flat or Miller Flat, then out). A 4-day itinerary adds flexibility for tide windows and cuts the daily sand-grinding mileage, which makes it a good choice for first-timers or anyone carrying a heavy pack. Plan camps around tide schedules first, mileage second.
Cooskie Creek has the best wind protection on the trail, tucked into a canyon with large, flat camping areas on hard-packed sand. Big Flat Creek has expansive beach camping with views but can be windy. Miller Flat has excellent tree-sheltered sites on the south side of the creek, one of the most comfortable camps on the route. Buck Creek is underrated, with both beach camping and hillside sites overlooking the ocean.
Elephant seal viewing peaks near Punta Gorda Lighthouse, where a colony of 200+ seals hauls out. Keep 50-100 yards of distance. Sea Lion Gulch has two rocks packed with bellowing Steller sea lions, hard to miss by eye or ear. Whale spouts (gray whales migrating December-March) and harbor seals are common.
Pack extra socks. Your feet will be wet from stream crossings, ocean spray, and morning dew on the beach grass. Consider camp shoes or sandals for creek fords and evening comfort. Gaiters help with sand infiltration but aren't essential.
Sandstorms can kick up without warning when winds exceed 15 mph. Pitch tents with doors facing away from the prevailing northwest winds and guy out thoroughly. Stakes don't hold well in soft sand, so bury guylines under driftwood or rocks and bring extra cordage for creative anchoring.
Mattole Campground has potable water if you need to fill up before starting. The closest hot meal and beer to Black Sands Beach is at the Shelter Cove RV Park store and deli. The Chart Room restaurant in Shelter Cove has ocean views and solid post-trail food; reservations are recommended on weekends.
