Crater Hot Spring
Crater Hot Spring emerges at 111°F near Saratoga Springs on Utah Lake state lands, delivering highly mineralized water with substantial calcium, sulfate, and moderate chloride from a distinctive thermal feature.
Located at 4,481 feet elevation near the eastern shore of Utah Lake in Utah County, the spring sits in terrain transitioning from valley floor to the Wasatch Front foothills. The Utah Lake basin features marshlands, irrigated agriculture, and rapid suburban development, though the spring's immediate vicinity remains relatively undeveloped. Annual precipitation averages 15.4 inches with 39.1 inches of snow. The spring lies 545 meters from the nearest road, requiring a moderate walk through valley terrain that has seen dramatic population growth in recent decades.
The Crater designation references the spring's distinctive geological formation, common for thermal features creating depositional mounds or depressions. Utah Lake's thermal springs were known to indigenous Ute peoples and noted by early Mormon settlers arriving in the 1840s. Some thermal features near the lake saw limited commercial interest, but detailed historical documentation for this specific spring is limited. Current public access status remains uncertain on state lands.
Access requires coordination with state land management given the uncertain public entry status. The 545-meter walk from roads requires navigation through potentially private or restricted areas. Water mineralization prohibits drinking. The spring's location amid rapid development means conditions may change. Little Mill Campground in American Fork Canyon, 21.7 kilometers away, provides developed facilities. Verify access permissions before attempting to visit this thermal feature near Utah's second-largest lake.
