Hidden away among the high Rocky Mountains of southern Colorado, the sand dunes are amazing. Backed into a corner of a huge valley, surrounded by 4,000m snow-capped peaks is an enormous field of dunes, some 200m high.
The scenery is stunning, wildlife (bison, elk, bears) diverse and there's plenty of opportunity for hiking etc. in the surrounding wilderness area.
Although a bit of a backwater, it can be reached quite easily from Denver or Santa Fe. There's accommodation in nearby Alamosa, and camping on site, but the last time I visited on a fall weekend it was crowded with snowboarders getting some pre-season practice.
