Helmet and Sphinx Professional Guide
Detailed Trail Description from our Guidebook
"This is a day hike or overnighter to the Sphinx and the Helmet in the Madison Range. The Madison Range undoubtedly offers some of Montana’s finest hiking.Yet only the northern section, the Spanish Peaks, has ever become popular with hikers.The area south of the Spanish Peaks all the way to the Hilgard Basin on the southern tip of the range offers good hiking also. The loop trail between the Sphinx and the Helmet nicely illustrates this fact.
Once you pick up Trail 325, it’s about 5 miles out to the road, making this a tough, 11.5-mile hike, not including the mountain climbs.The Middle Fork and a smaller stream on the climb are the only reliable water sources, so plan on carrying water with you."
