Sand Dune Arch Trail
What to Expect
Safety Advisory
The deep sand gets extremely hot in summer — surface temperatures can exceed what bare feet can handle between late morning and early evening from June through August. Test it with your hand before letting kids go barefoot.
Do not climb on or around the arch. The sandstone is fragile, and falls from even modest heights onto hard-packed sand have sent visitors to the ER.

Pro Tips
Hit this trail early morning or late afternoon — the narrow canyon between the fins is one of the few shaded spots in Arches, but midday sun still bakes the open sections of the parking area and approach.
The sand is deep and loose underfoot, so skip the hiking boots and wear sandals or trail runners. Barefoot works too if the sand isn't scorching. Traditional hiking shoes just fill up with sand.
Combine this with Broken Arch Trail, which shares the same trailhead. You can loop both in under an hour and get two arches for the price of one parking spot — a smart move during peak season when lots fill up.
