Mountains of sand rise out of a dune field covering nearly 30 square miles. One of the dunes – Star Dune – at 750-feet high would reach half-way up the Empire State Building.
The best day hike through the sand dune is the 2.5-mile round trip High Dune Trail. It heads to High Dune, which rises 650 feet, and offers a view of Star Dune just beyond it.
Here’s a panning shot of the sand dunes:
