Alamosa National Wildlife Refuge is a fairly interesting place to get a close glimpse of the San Luis Valley and its inhabitants. This preserve is just a few miles east of Alamosa on highway 160. There is an auto tour loop near the visitor center (which may or may not be open at the moment), that encompasses some marshy areas affording opportunities to view wildlife such as waterfowl and mammals such as deer. Additionally, there is a fairly expansive overlook eight miles from the refuge entrance where elk can supposedly be seen on occasion. The view of the valley and San Juan Mountains in the distance, even without the wildlife, is pretty inviting, especially when there are thunderstorms fomenting in the distance. There is a trail here and also at the visitor center. Be advised that the overlook can be a little hard to find. One other nice perk about this attraction is that it is free and mentally refreshing!
