Current Soaking Conditions

Lower Breitenbush Hot Springs, also known as Ann Arbor Hot Springs, offers a riverside soaking experience amidst the skeletal beauty of a 100-year-old abandoned resort. Unlike the polished retreat nearby, this public site features rustic cement tubs and a cast-iron bath perched right on the edge of the rushing Breitenbush River. It is a place where nature is reclaiming history, offering a quiet, clothing-optional sanctuary for those who prefer grit over luxury.

Hot Pool Details

Quantity: 2 to 4 distinct soaking areas, depending on river levels.
Substrate: Remnant concrete tubs, cast-iron basins and natural river rock.
Pool Features: Temperatures vary wildly (65°F to 125°F) based on the positioning of hoses used to divert 150°F source water into the tubs.
Environment: Riverside exposure with views of the canyon and recovering forest; the setting is highly affected by the 2020 Lionshead Fire.
Pro Tip: Bring a small bucket. The water coming from the hoses can be scalding (150°F+), and you may need to mix in river water to reach a comfortable temperature.

Seasonal & Access Restrictions

Winter Access: Road 46 is not plowed regularly; chains or 4WD are often required from November to April.
Spring Runoff: High river levels in May and June frequently wash out the riverside tubs, making them too cold or inaccessible.
Summer/Fall: High fire danger is common. Check the Detroit Ranger District for current Public Use Restrictions (PURs) before visiting.

Rules, Etiquette & Crowds

Nudity Level: Historically clothing-optional; please be respectful of other soakers.
Crowd Factor: Moderate on weekends; weekdays or early mornings provide the most solitude.
Regulations: No dogs in the hot springs pools; dogs must be on a leash in the surrounding forest. No glass bottles allowed.
