What is a BLM GTLF route, and can you drive it to camp?
A BLM GTLF route is a road in the Bureau of Land Management's Ground Transportation Linear Features inventory — the BLM's legal record of its routes, classed by level (L0–L3). Like a Forest Service MVUM road, it carries a legal motorized designation: it tells you the BLM recognizes the route, not just that a track exists on the ground.

Like a Forest Service MVUM road, a GTLF route carries a legal motorized designation: it is the BLM's recognized route inventory, the agency's record of which routes exist and how they're managed, not merely a track that appears on satellite imagery. We draw GTLF routes as designated motorized roads alongside the MVUM because both carry that legal weight, and because finding a legal, drivable route is the first step to a legal dispersed campsite on the gold BLM land around it. A designated route is still not a camping permit — verify the field office's travel-management plan and any closures.
Common questions
- What does GTLF stand for?
- Ground Transportation Linear Features — the Bureau of Land Management's official inventory of roads and primitive routes on BLM land, classified by level from L0 (most primitive) to L3 (maintained road). It is the BLM's legal route record.
- How is a GTLF route different from a regular road on the map?
- A GTLF route carries a legal motorized designation from the BLM — the agency recognizes and manages it. A county or TIGER line records only that a road physically exists. The two are drawn differently because only one is a legal designation, and neither is a camping permit.
- Can you camp along a BLM GTLF route?
- Often, yes — dispersed camping is generally allowed on open BLM land near a drivable route, up to a 14-day limit, but the route being designated doesn't by itself make a campsite legal. Check the field office's travel-management plan and any posted closures first.
