America 250: A Short History of Idaho’s Hulls Gulch — How Boise Almost Lost One of Its Most Beloved Natural Spaces
Boise, Idaho — For many residents of Ada County and the broader Treasure Valley, the Boise Foothills are practically a backyard. And for decades, Hulls Gulch Reserve — located just north of downtown Boise near Camel’s Back Park — has served as one of the most popular gateways into that wild, open landscape. As America marks its 250th anniversary in 2026, a new local history project is shining a light on the small corners of Idaho’s capital city that shaped the community residents know today, including a gulch that nearly disappeared beneath hundreds of new homes.
A Name Rooted in Idaho’s Earliest Days
Hulls Gulch has carried its name since at least 1867 — just four years after the founding of both the Idaho Territory and Boise City itself. The exact origin of the name remains something of a historical mystery, though it is widely believed to honor members of the Hull family, who arrived in Idaho Territory during the 1860s. Bureau of Land Management records show a state volume patent issued to Samuel G. Hull in 1874, lending credence to the family connection.
The gulch is defined by its creek, which winds through the landscape and carves a natural path into the foothills. Today, visitors can access more than 100 miles of trails through the Ridge to Rivers system from its trailheads. The area serves not only as a recreational hub for cyclists, hikers, and runners, but also as an important wildlife corridor. Great horned owls, coyotes, red foxes, mule deer, and snakes all call the gulch home.
How Boise Almost Lost Hulls Gulch
Despite its seemingly timeless character, Hulls Gulch came remarkably close to being erased from Boise’s landscape entirely. In 1989, a development proposal called for stripping the gulch of its vegetation and constructing hundreds of homes on the site. The prospect galvanized the community in a way that would become one of Boise’s most memorable grassroots conservation efforts.
Under the rallying cry of “Save Hulls Gulch!”, thousands of volunteers organized to raise funds and advocate for the area’s permanent protection. Local students formed their own group, calling themselves the Hulls Angels, and joined adults in pushing back against the development plan. The campaign drew broad community support and sustained momentum over several years.
The effort paid off. Between 1991 and 1993, the majority of Hulls Gulch Reserve was permanently protected. The City of Boise coordinated a land trade with property owners, while additional purchases were funded through a combination of city resources, federal government support, and contributions from Boise residents themselves. It was a coalition effort that reflected the community’s deep attachment to the open foothills that frame the city’s northern skyline.
Impact on Ada County Residents and the Foothills Legacy
The protection of Hulls Gulch set a precedent that Ada County voters have reinforced repeatedly in the decades since. Boise residents have approved multiple tax levies to preserve thousands of acres of foothills open space, ensuring that public lands like Hulls Gulch remain accessible and undeveloped for future generations. That commitment to preserving open space has become a defining feature of Boise’s civic identity and a point of local pride across the Treasure Valley.
Today, Hulls Gulch Reserve draws residents from across Ada County — from Boise and Meridian to Eagle and beyond — who come to hike, run, and mountain bike within minutes of the city’s urban core. The reserve stands as a testament to what organized community action can accomplish when residents invest directly in their shared landscapes. Visitors exploring Boise’s broader community events and outdoor culture can also find the Junior League of Boise’s annual walk celebrating the impact of women in Idaho among the local traditions that reflect the city’s engaged civic spirit.
What Comes Next: America 250 in Idaho
The Hulls Gulch feature is part of the ongoing America 250: Short Histories of Boise project, produced in collaboration with the City of Boise’s Department of Arts & History and with support from Boise State University’s History 502 class. Each Monday on Idaho Matters, the project delivers a snapshot of a different corner of Boise’s past.
The project’s musical component features “Liberty Fanfare” by John Williams, recorded by the Boise Philharmonic — the City of Boise’s Cultural Ambassador — in 2025.
