Launching in San Francisco
Walk the city's defining neighbourhoods with a guide who actually lived them. Each stop unlocks when you're physically there. When you arrive, they'll tell you what they saw.
$25 per quest · $60 for the full SF pack · No app download needed
How it works
EraHopper is a mobile web app — no download, no app store. Open it in your browser, pick a quest, and walk. When you arrive somewhere, you stop and listen.
Each quest is a walk through a neighbourhood's defining era, narrated by someone who lived it. 5–6 stops, about 2 hours. Stop and restart whenever you like.
Walk to the first stop. When you arrive, point your phone at what you find there. Someone who lived history will be waiting to tell you what they saw.
Each stop unlocks a new chapter — audio, photographs, maps. Your guide moves through time as you move through the city. The walk is the narrative.
Photograph artifacts along the way. Some are obvious. Some are hidden in plain sight. Some won't make sense until later — on this walk, or on a different one entirely.

V1 · 2026
The waterfront that invented the word "shanghai" — the crimping dens, the saloons, and the city that somehow tolerated all of it for sixty years. Your guide was there for most of it.
City Lights, Vesuvio, the Six Gallery reading where Howl was first performed. The neighbourhood before the tourists arrived — and why those years could only have happened here.
He worked these streets as a Pinkerton operative before he wrote them. Follow the blocks that became Spade's city — and find out which ones were real.
Heritage Drinks
Each quest has 1–2 stops at real SF businesses where history lives on today. Try the Pisco Punch at the Old Ship Saloon — invented two blocks away in 1872, banned in 1920, recently resurrected.
Sometimes off-menu and sometimes not, real-life stops bridge the city's past and present.
Your Personal Scrapbook
Every stop, every artifact, every person you meet goes into your scrapbook. Some slots are filled the moment you arrive. Others you'll have to look for. A few won't make sense until you've walked somewhere else entirely.
Each stop you complete is saved permanently — the audio, the photographs, the chapter your guide told you.
Photograph artifacts to fill the slots in your scrapbook. Some are easy to find. Some are hiding in plain sight.
Every story links its sources. Read deeper if you want — or just walk on.
Come back to a stop and new layers may have unlocked. The scrapbook keeps filling in.
"This is not the San Francisco you think you know. It's the one underneath." — EraHopper, Barbary Coast Trail
