Heise Hot Spring

## Overview Heise Hot Spring is a geothermal hot spring located in eastern Idaho, near the banks of the Snake River at approximately 43.643°N, -111.688°W. Situated in the heart of the upper Snake River Plain — a region shaped by ancient volcanic activity and the passage of the Yellowstone hotspot — Heise Hot Spring draws its warmth from deep geothermal systems that heat groundwater as it circulates through fractured volcanic rock far below the surface. The Heise area has long been known for its geothermal features. The name "Heise" is associated with the historic Heise Hot Springs resort, which has operated in this part of Jefferson County, Idaho, for well over a century. The hot springs in this area have historically attracted visitors seeking the reputed therapeutic benefits of naturally heated mineral water. The geothermal waters here have been reported to contain dissolved minerals typical of volcanic hot springs in the region, including silica and various trace elements, though specific water quality analyses for this particular spring point are not confirmed. The spring is located roughly 25 miles east of Idaho Falls, in a scenic stretch of the Snake River valley framed by rolling hills and cottonwood-lined riverbanks. The surrounding landscape offers views of the eastern Idaho high desert transitioning into the foothills that lead toward the Caribou-Targhee National Forest and, further east, the Teton Range. ## Directions 1. From **Idaho Falls, ID**, head east on **US-26 E** toward Swan Valley. 2. Continue on US-26 E for approximately **22–25 miles**, following the Snake River canyon. 3. Watch for signs indicating **Heise Hot Springs** or the Heise area on the left (north) side of the highway. 4. Turn left onto **Heise Road** (also known as **4988 N Heise Rd** in some GPS systems) and follow it north toward the river. 5. The hot spring area is located near the end of Heise Road, close to the Snake River. GPS coordinates: **43.643112, -111.688440**. *Note: These directions are based on the GPS coordinates provided and general knowledge of the Heise area. Road conditions and access points may vary seasonally — it is advisable to check current conditions before visiting, especially in winter months.* ## What to Expect Visitors to the Heise Hot Spring area can expect a geothermally active zone along the Snake River corridor. The surrounding terrain is characteristic of eastern Idaho's volcanic landscape — basalt formations, sagebrush-covered hills, and riparian vegetation along the river. The Heise area is well known for its developed hot springs resort (Heise Hot Springs), which features pools, a waterslide, and campground facilities. This specific spring point, based on its GPS coordinates, may be located near or associated with the broader Heise geothermal area. Visitors should be aware that some hot spring features in the area may be on private property or within the resort grounds, and access may require an admission fee. Water temperatures at geothermal springs in the Heise area have historically been reported as quite warm, typical of Idaho's volcanic hot springs. As with all natural hot springs, water temperatures can vary and may be extremely hot near the source — exercise caution and test water temperature before entering. The area is accessible year-round, though winter travel on surrounding roads may require appropriate vehicles. The Snake River corridor near Heise also offers opportunities for fishing, hiking, and wildlife viewing, making it a worthwhile destination beyond the hot spring itself.
