Twelvemile Hot Springs Trail

The access road to the hot springs is notoriously rough, unmaintained, and often features significant potholes, ruts, and creek crossings. A high-clearance vehicle is highly recommended, and 4WD can be essential, especially during wet or snowy conditions. If you have a lower clearance vehicle, you may need to park earlier and walk an additional 2 miles to reach the start of the hiking portion. There are no signs marking the trailhead, so relying on maps or GPS is advised.

While there are no explicit restrictions mentioned, it's generally understood that dogs are allowed on this trail. However, be prepared for the challenging access road and potential creek crossings, which might be difficult for some pets. Always keep your dog under control and pack out all waste.

The hot springs are accessible year-round. Late fall, winter, and early spring are particularly popular due to the striking contrast between the warm water and the crisp mountain air. However, winter visits require extra caution due to potentially impassable road conditions and deep snow on the trail.

No, despite being located on private land, the Twelvemile Hot Springs are generally freely accessible to the public, and no permits or entrance fees are required.

Once you navigate the access road, the hiking portion itself is generally considered a flat, approximately 2-mile walk. However, you will encounter multiple creek fordings, which can be shallow in dry seasons but deep during high water. An old, uncrossable bridge also means you'll need to find an alternative way to cross the creek. In winter, deep snow can make snowshoes necessary.

The overall difficulty ranges from moderate to challenging, primarily due to the extremely rough and unmaintained access road. The road often has significant potholes, ruts, and creek crossings, making a high-clearance or 4WD vehicle essential. The hiking segment itself is relatively easy, but the road conditions are the main hurdle.

The hot springs are a natural oasis with water temperatures typically ranging from 102°F to 105°F. They feature a long, man-made concrete pool, approximately 40 to 80 feet long, 8 to 9 feet wide, and 2 to 3 feet deep, with a gravel bottom. A concrete wall separates the pool from Bishop Creek. Clothing is optional, and the area usually has low foot traffic, offering a peaceful soaking experience.

The trail and surrounding area offer beautiful natural scenery. You'll follow a meandering warm creek through a spectacular narrow canyon, flanked by high rock walls and rolling hills. It's a picturesque journey to a secluded natural oasis.

If you don't have a high-clearance or 4WD vehicle, your best strategy is to park earlier on the access road where it becomes too rough for your vehicle. Be prepared to walk an additional distance, potentially up to 2 miles, to reach the start of the main hiking trail. Always check current road conditions before heading out.

The hiking segment itself is considered relatively easy and flat, making it suitable for most skill levels. However, the significant challenge lies in navigating the very rough access road and potentially deep creek crossings. If you can manage the road conditions (either by driving an appropriate vehicle or being prepared for a longer walk), the hike itself is beginner-friendly.
