Natural Bridge located in Bryce Canyon National Park is misnamed as it is in fact an arch. It is 85 feet high and is easily accessed from the Bryce Canyon rim drive – it is only steps away from the parking. The way the land falls away from it offers a nice view and photo opp. There are no hiking opportunities around the arch as the ground is too steep.
Bryce Canyon has myriads of small arches (I’d call them windows), but Natural Bridge is easily the best of them. There are two artificial arches that you can drive through along state road 12 in Red Canyon state park which is near Bryce Canyon. They are technically tunnels, but if looks and feels more like driving through arches.
Bryce Canyon National Park is located in southwestern Utah and is well worth your time. You can read about it here.
