You don’t so much arrive at Hilltop Treehouse Retreat as earn it. First, a 40-minute ferry ride from the mainland, waves fanning out behind you, Lopez Island coming slowly into focus. Locals call it the “Friendly Isle,” and the nickname fits; even the gulls seem unhurried here. By the time you reach the trailhead, city noise has slipped clean out of your pockets.
Then you look up—and there it is. A wooden dwelling tucked high in the evergreens, clinging to a cliff above the Upright Head Channel. The air smells of salt and pine resin. The light, somehow both sharp and soft, filters through Douglas fir needles and lands on cedar shingles like gold dust.
This isn’t just a rental—it’s a story in mid-air. Designed by Tom Froning of Soundesign, the treehouse floats between two old firs on a platform engineered to move with the wind. Step inside and you can feel it—just a whisper of motion, enough to remind you that you’re part of the landscape, not just looking at it.
The interior feels timeless, as if it’s been hanging here for decades, aging gracefully with the trees. Celtic carvings wrap around the beams. Counters and desks are shaped from live-edge slabs, still rippling with the grain of the forest. Storage comes in the form of antique boxes, the kind that look like they have stories to tell, and a weathered rocker waits by the window, facing the sea.
Huge panes of glass frame the channel below. Ferries drift past like lazy punctuation marks; the sun dissolves into watercolor streaks at dusk. It’s an ever-changing show that needs no script. On clear nights, stars scatter so bright they reflect off the water, doubling the constellations.
Outside, the Upright Head Preserve stretches over 26 acres of moss-draped trails and sudden overlooks. One minute you’re under cathedral-tall firs; the next, staring out at open ocean. There’s always that subtle Pacific soundtrack—wind, water, the occasional cry of a gull that sounds suspiciously like laughter.
It’s no wonder Airbnb lists Hilltop among its “Top 10 US Treehouses,” or that the Seattle Times and KING5 audiences can’t stop talking about it. But awards don’t really capture its charm. What you’ll remember is the hush between waves, the way the house sighs gently in the breeze, the feeling that for a moment, everything—design, landscape, you—has found its rhythm.
Rates start around €220 per night on Airbnb. Bring a book you won’t read, shoes you don’t mind muddying, and a readiness to feel small in the best possible way.
