Frequently Asked Questions
Check the Idaho BLM camping guide, Forest Service MVUM guidance, and the current local order. Our camping guide explains the differences by land manager.
Can I camp anywhere on BLM land in Idaho?
No. Camping depends on local restrictions and legal access. Idaho BLM’s published guide describes a 14-day-in-28 stay limit, a 25-mile move, and at least 200 feet from water for dispersed camping. Check current field-office orders and posted signs before choosing a site.
Do I need a permit for dispersed camping in National Forests?
Requirements differ by forest and location. Check the ranger district for permits, stay limits, designated-site rules, and closures. Do not apply one forest’s rules statewide. Wilderness permits do not authorize motorized access into designated wilderness.
What is an MVUM and why does it matter?
The Motor Vehicle Use Map (MVUM) is the official map showing which roads and trails are open to motorized vehicles on National Forest land. Travel is only allowed on designated routes shown on the MVUM. Using unauthorized routes is illegal and subject to fines.
Can I drive on BLM land anywhere I want?
No. Use the BLM field office’s current travel-management map and orders to confirm which routes allow your vehicle. A public-land color or visible track does not establish permission, and temporary closures may apply.
What should I bring for backcountry travel in Idaho?
Essential items include: full-size spare tire, recovery gear (traction boards, straps, shovel), extra fuel, water (1 gallon per person per day minimum), paper maps/GPS, first aid kit, fire extinguisher, and communication device (cell service is often unavailable).
When are forest roads open in Idaho?
There is no statewide opening date. Snow, mud, washouts, seasonal restrictions, and temporary closures affect individual roads. Check the current travel map and the managing agency’s road and closure notices; a listed route is not a live condition report.
