Fiery Furnace may not be home to the monoliths for which Arches National Park is best known but this labyrinth of narrow sandstone canyons and fins is one of the park’s most spectacular places. Even for families that regard guided tours with trepidation. Not only is Fiery Furnace next to impossible to navigate without prior experience – there are no marked trails and GPS devices are all but useless in this maze of geological formations – the knowledgeable guides make the experience interesting and fun for both adults and kids. Natural arches, fins and bridges are but the start. Potholes, biological soil crust, self-pruning juniper trees and the mysteries of pack rat debris await families that partake in a ranger-led hike in nature’s jungle gym.
