Twin River Heritage Rangeland Natural Area is an Alberta Parks natural area in the South region, 20 kilometres west of Milk River. Alberta Parks lists no developed day-use area count and surfaces hunting as the official activity.
All of this land is under grazing lease and requires leaseholder permission to access.
Twin River is a very large heritage rangeland for visitors researching hunting, grassland habitat, grazing-lease access, and rare wildlife in southern Alberta. Alberta Parks lists the site at 47,016.41 acres, or 19,027.54 hectares.
The park-management profile places it in the Grassland - Mixedgrass and Grassland - Foothills Fescue natural regions. Alberta Parks notes dense nesting bird-of-prey populations, including ferruginous hawks, golden eagles, and prairie falcons.
The official page also lists rare yellow-bellied marmot and leopard frogs, rare fish including mottled sculpin, stonecat, and finescale dace, and rare plants including prickly milk vetch, tufted hymenopappus, and Carolina whitlow grass.
Access and livestock etiquette are central. Visitors must leave gates as found, avoid harassing cattle, and slow down near livestock. Some hunting areas have grazing-lease access restrictions.
Because the site is large and leased, access planning should come before route ambition or hunting plans.
Plan around hunting where permitted, leaseholder permission, grassland and rangeland research, bird-of-prey observation, rare species awareness, gate etiquette, and map review.
Confirm leaseholder permission, access restrictions, grazing rules, hunting regulations, licences, boundaries, maps, road conditions, weather, and Alberta Parks updates before travelling.
