UpValley Inn and Hot Springs

## Overview UpValley Inn and Hot Springs is located in the upper Napa Valley region of California, near the town of Calistoga — an area long celebrated for its natural geothermal activity. Calistoga sits at the foot of Mount Saint Helena, where volcanic geology produces naturally heated mineral waters that have drawn visitors for well over a century. The town's hot springs tradition dates back to the indigenous Wappo people, who used the thermal waters for bathing and healing long before European settlers arrived. In the 1860s, entrepreneur Sam Brannan developed the area as a resort destination, famously dubbing it the "Saratoga of California" (which, legend has it, came out as "Calistoga" instead). UpValley Inn and Hot Springs (GPS: 38.5861, -122.5771) offers access to these geothermally heated mineral waters in the heart of Calistoga. The property provides hot spring pools fed by the area's natural thermal aquifers, which are characteristic of the region's volcanic geology. Calistoga's hot springs are known for their mineral-rich composition, typically containing varying levels of sulfur, bicarbonate, and other dissolved minerals — a result of groundwater being heated deep underground by residual volcanic activity and rising through mineral-laden rock formations. The hot springs in this part of Napa Valley generally range in temperature from around 80°F to over 100°F, depending on the source and how the water is managed at individual facilities. Visitors have historically reported that the mineral waters feel soothing and rejuvenating, and the Calistoga area has long been associated with wellness and relaxation. ## Directions 1. From downtown Napa, head north on CA-29 (St. Helena Highway) through the Napa Valley wine country. 2. Continue on CA-29 through the towns of Yountville, Oakville, Rutherford, and St. Helena. 3. As you approach Calistoga (approximately 30 miles from Napa), the road becomes Lincoln Avenue as it enters town. 4. UpValley Inn and Hot Springs is situated along this main corridor in Calistoga, near the intersection of Lincoln Avenue and the surrounding resort area. 5. Look for the property signage along the road. GPS coordinates (38.5861, -122.5771) can be used for precise navigation. ## What to Expect Visitors to UpValley Inn and Hot Springs can expect a hot springs experience set within the scenic upper Napa Valley. The area is surrounded by rolling vineyards, oak-studded hillsides, and the dramatic profile of Mount Saint Helena to the north. Calistoga is a small, walkable town with numerous tasting rooms, restaurants, and shops nearby. The hot spring pools on the property utilize the area's naturally heated geothermal water. As with most Calistoga hot springs, the water may carry a faint mineral scent — a hallmark of the region's volcanic origins. The surrounding area offers additional attractions, including the Old Faithful Geyser of California and the Petrified Forest, both just a short drive away. Calistoga enjoys a Mediterranean climate with warm, dry summers and mild winters, making the hot springs a year-round destination — though the pools can be especially inviting during cooler months. The area can get busy during peak wine country tourism season (typically late summer through fall harvest), so planning ahead is recommended.
