RV travel guide
Ada County
County seat Boise, 1,055 sq mi across Idaho. Everything an RV traveler should read before rolling in — where you can boondock, the roads worth the detour, and the local rule that actually matters.

The county in brief
A traveler's read on Ada County
Boise is the most-populated US state capital not located on or near a major navigable waterway — the Boise River through downtown is a Class II rapids urban-greenway with a 25-mile paved greenbelt connecting the city's parks, but no commercial barge or shipping access.
Ada County is the most-densely populated county in Idaho with 469 persons per sq mi but is only the 4th-largest by area (1,055 sq mi). Boise National Forest's southern foothills (Bogus Basin Recreation Area) hold the closest dispersed-camping public land to any state capital in the West, with the Boise Front rising from 2,700 ft city elevation to 7,582 ft Bogus Basin summit in 16 paved miles.
