A designated national natural landmark and wilderness study area, Hell’s Half Acre Lava Field is a basaltic lava plain found in the desert ecosystem of the Snake River Plain of Idaho. It consists of about 150 sq miles of other-wordly terrain created by a lava flow from about 4,100 years ago. There’s a 1/2 mile trail marked by blue poles, you can follow those to the red poles that lead you out 4.5 miles to the central vent, where the lava broke through the surface thousands of years ago (9.4 mile round trip).
Hiking across a lava field is not for everyone, especially not for the tender footed. It’s cool, but the novelty wears off fast. While the trail is flat and easy, the terrain itself is tough and unforgiving. Lava rock is extremely sharp – like glass shards- and fragmented and the field is a trap of open cracks, gaping holes, jagged rocks and uneven, tortuous footing. It’s slow and treacherous going. One misstep can land your foot or your body in a hole. And if you trip, you’re likely to be broken, bruised or bleeding. Sneakers are not enough, the lava will eat them up. I’d recommend sturdy hiking shoes even for the short stroll. Also, it’s easy to get lost in the vast monotonous beauty of the lava field, you really have to look for those trail pole markers. Not a hike to set the kids loose on. Do not attempt the long hike in the summer as this place gets hot as hades.
Normally, I’m up for a hiking challenge, but I was happy to keep it short here, especially when I heard the rednecks firing shotguns close by…(sigh).
