Hunting
New Mexico and Colorado Game Unit Maps, Offline on Your Phone
Last checked
New Mexico and Colorado both organize hunting by numbered game management units, often called GMUs. Know your unit before you buy a tag, then download its map so your phone's GPS dot works in country with no cell service.
Check boundaries and seasons with the New Mexico Department of Game and Fish and Colorado Parks and Wildlife. They are the authority. A map is an aid, not a guarantee.
Pick your unit
New Mexico units are at /hunting-units/new-mexico and Colorado units are at /hunting-units/colorado. Open the unit's map, download it on Wi-Fi, and go.
Why offline matters
Most of the good country in both states has no cell service. A map that is already on your phone keeps showing where you are, because GPS does not need a signal. Canyons, deep timber and high ridgelines are exactly where a streaming map gives up.
- Choose your unit and open its map.
- Download it on Wi-Fi before the drive.
- Test it in airplane mode.
- Save neighboring units if you may hunt along a boundary.
Public land inside units
Many units mix national forest and Bureau of Land Management land, and private inholdings sit in between. A downloaded map helps you see which ground is which before you commit to a long walk. For forest roads and which ones are open, see how to read a motor vehicle use map. For choosing public ground, read how to find public hunting land on a map. You can also browse all maps for Bureau of Land Management and Forest Service coverage.
