There's No Trail on the Lost Coast

Lost Coast Trail, King Range, CA · February 2022 · 3 nights

On paper, the Lost Coast is the one trail you cannot get lost on. You walk north to south, which means the ocean is on your right the entire way. Keep the Pacific off your right shoulder and you are, by definition, heading the right direction. What could be simpler? The catch is that the beach is not always walkable, and where the sand runs out the route climbs up and over high bluffs before dropping back down to the shore. Up on those bluffs the trail is not always there.

Down on the sand the navigation really is that simple. Keep the ocean on your right and walk south. The parts where you can't stay on the sand are the ones that get interesting.

This was February, the off-season, when the King Range belongs to the storms and the elephant seals and almost nobody else. We left the car at Black Sands Beach, the southern end, and caught the shuttle up the long dirt road to the Mattole trailhead at the north, which is the standard way to run the trip, so you finish the walk at your own car instead of a long way from it. From there the route runs about twenty-five miles of roadless coast back south, the longest undeveloped stretch of shoreline left in the lower forty-eight. The plan was three days of walking, north to south, ocean on the right. I figured route-finding would be the least of our worries.

Day 1 Walking off the edge of the map

Mattole, the north trailhead. The last sign we'd see for a day and a half.

First night, camped right at the Mattole trailhead before we'd walked a single mile. That's not coffee in my cup, but a little bourbon to toast the start of the trip.

We camped that first night at the Mattole trailhead itself and set out the next morning. From Mattole the "trail" is just the direction south. The ground keeps changing under your boots, from soft black sand in places to fields of round cobble in others, with the occasional pile of driftwood logs the size of telephone poles to clamber over. The rule stays the same throughout, which is to keep the ocean on your right and keep going. The first stretch took us past the old Punta Gorda Lighthouse, squat and white on a green bench above the surf, and past a sprawl of elephant seals lounging on the beach like enormous gray sandbags, snorting and shifting and entirely unbothered by us.

The locals. You give them a very wide berth and they ignore you completely.

For long stretches the navigation really is as easy as advertised, with the ocean on the right and one foot going in front of the other. But the coast doesn't let you stay on the sand the whole way. Cliffs push right down to the water, the beach pinches out, and the route is forced up onto the headlands. You climb a steep bluff trail away from the shore, traverse the green benches up top, and then drop back down to the beach on the far side. Sand, surf, headland, and climb, over and over. That rhythm is the whole trail, and that rhythm is also where the simple rule stops being simple.

The tide A trail that closes twice a day

Cobble at the base of the cliffs. There are stretches here you do not want to be standing on at the wrong hour.

The Lost Coast humbles people for a second reason, which is that several sections are passable only at low tide. The cliffs come straight down to the water, and when the tide is in there is no beach at all, only rock and surf and nowhere to go. People have been caught in those zones. The route is a line in time as much as a line in space, and getting the timing wrong costs more than a longer walk. We planned our days around the tide chart, started early, and pushed through the impassable stretches with hours to spare, camping at Spanish Flat the second night and Gitchell Creek the third. That part we got right.

The bluffs Where the trail isn't

Down on the sand, the ocean keeps you honest. Up on a bluff, two hundred feet above the surf, that handrail is suddenly a long way off to your right and useless. "Ocean on the right" tells you nothing when the problem is the cliff standing between you and the water. Up there the route is a faint use-trail braided through the grass and brush, and half the time the tread isn't where you expect.

Up on the benches. The ocean is still on your right, and now “right” means a cliff edge rather than a direction you can walk.

Nobody tells you this until you are standing on the ground yourself. The Lost Coast is not a surveyed, maintained, blazed trail like the ones in a national park. The route is dynamic, and the whole coast is actively coming apart. Winter storms tear out sections, bluffs slump into the sea, creek mouths migrate, and the brush reclaims the benches. The line hikers walked last year may be gone or rerouted this year. There are stretches where you're following the faint braid of everyone who came before you, and stretches where that braid just fades into the hillside and leaves you guessing which gully actually drops back down to the sand.

That is exactly where we kept losing the trail. You top out on a bluff, the path forks or dissolves into the grass, and you commit to whatever looks most worn, only to find yourself sidehilling across a slope that's quietly pushing you inland, or standing above a drop with no safe way down. When the fog rolled in off the water the guessing got harder, because the few landmarks we had left went soft. Nothing about the day was dramatic. But every time the trail vanished under us, there was that small cold beat of wait, are we still on the route?

The rule that keeps you found on the beach abandons you on the bluff. And the trail up there changes every winter, with no regard for what the map used to say.

We had the route loaded on a phone, and that is the only reason the bluffs were a nuisance rather than a problem. Every time the path disappeared, one of us would check the little blue dot against the line and pick our way back onto the route. But you have to remember to look. With cold hands, a heavy pack, and a use-trail that keeps lying to you, "check the map" is exactly the habit that slips at the worst moment. What I kept wishing for, up on those benches, was a phone that would check for me, one that would notice I'd wandered off the line and say so instead of waiting for me to wonder.

Day 3 Black sand, blue sky

The fog burned off the way it always eventually does, and the coast handed back every one of its landmarks at once.

The last morning the fog burned off and the Lost Coast turned into a postcard, with black sand stretching to a blue horizon, sea stacks standing in the surf, and the King Range green and sharp behind us. A place like this forgives you almost unfairly fast. We walked the final miles into Black Sands Beach in full sun, legs wrecked, completely happy.

The lesson Something that watches the line for you

Every feature in this app came from a specific moment on a specific trail. The off-trail alert came from those Lost Coast bluffs, and from the realization that staying on route takes more than having the map. Staying on route means noticing, in the exact moment the trail disappears under you, that you've stepped off the line. People get into trouble when the path quietly stops being where they assumed, rather than when they are studying the map.

So Backpackers Friend watches the line for you. Load your route before you leave, even an unpredictable, ever-changing route like the Lost Coast, and while you're tracking the app keeps measuring how far you have drifted from that line. Wander far enough off course, up a wrong bluff or into the brush or down the wrong gully, and the app alerts you with a notification and a vibration that works even with the phone in your pocket and the screen locked. You don't have to remember to check. The app checks, and the app taps you on the shoulder when the drift matters.

It will not get you out of a place like the Lost Coast. You still have to read the tide chart, start early, and respect the ocean. But the app gives you back what a dynamic trail takes away, which is the certainty that even when the path itself has moved, something will speak up before the wilderness does if you drift off your line.

Don't drift off course

Backpackers Friend lets you build a route on a topo map before you leave, then watches your position against that route while you hike. Off-trail alerts notify and vibrate the moment you wander too far, even with the screen locked. The app works completely offline, so the watching continues with no signal.
