Alum Rock House
In the 1870s and 1880s, a rustic lodge stood on the south side of the canyon, just across from what is now the main bridge over Penitencia Creek. Nestled between groves and mineral springs, the lodge provided food, shelter, and a quiet escape for travelers, locals, and health-seekers drawn to the area’s bubbling waters.
This was more than just a place to sleep — it was part of an early tourism movement in California, when natural parks were seen as spaces for rejuvenation, reflection, and even cure. People arrived by carriage or on foot to soak in the hot sulfur baths, drink from the springs, or hike the canyon’s wild trails.
Sadly, this early structure burned down in 1890, taking with it a tangible piece of San Jose’s hospitality past. Few images remain (one, dated c.1885, is preserved at the San José Public Library California Room), but the spirit of that place — a stopover between land and healing — still lingers in the park’s natural quiet.
