While Sepulcher Mountain itself is a strenuous hike, the area around Mammoth Hot Springs offers several less challenging and family-friendly trails. These include boardwalks around the terraces and shorter loops that provide beautiful views and opportunities for wildlife spotting without the demanding elevation gain of the summit trail.
