Bosque del Apache National Wildlife Refuge
Bosque del Apache is one of the Southwest's great winter bird stages, where wintering sandhill cranes, snow geese and Ross's geese gather along the Middle Rio Grande from late fall into winter. According to the U.S. Fish & Wildlife Service, you will find the greatest numbers of birds at the refuge from early November to late January, when thousands roost on water overnight and lift off near dawn to feed in valley fields. For RVers it is a classic dawn-and-dusk destination: park nearby, drive the refuge auto-tour loop, and time your mornings for the fly-out. The refuge itself is day-use, so plan to base your rig in or near Socorro.

Plan it honestly
Migration and wintering timing vary year to year with weather, and peak counts are never guaranteed. The refuge is a day-use auto-tour loop with trails — no camping on site. Check at the visitor center for current roosting and feeding locations before heading out, and respect closed areas.
