Weir Creek Hot Springs, Idaho

Weir Creek Hot Springs is a hike-in soaking area located just off Highway 12 in north-central Idaho, east of Kooskia. The approach is brief, but the setting feels wild, with dense forest, steep canyon walls, and the steady sound of rushing water.

A small hike with a real payoff

The trail descends quickly from the highway to the creek. Once you reach the water, a series of informal rock pools appear along the warm outflow. Pool size and depth change with runoff and use, and there is no single “main” pool that stays the same year to year.

Popularity shaped by access

The short hike makes Weir Creek a frequent stop for people traveling the Lochsa corridor. On warm days it can feel busy, while early mornings and weekdays are noticeably calmer. The ease of access is the draw, and also the tradeoff.

Where it is

Weir Creek Hot Springs is accessed from a signed pullout and trailhead along Highway 12 in the Nez Perce–Clearwater National Forests area.

The hike

The hike is short, but the trail can feel steep, especially on the climb back up. In winter and shoulder seasons, ice and packed snow are common, making traction important.

Day-use management

Forest managers have implemented overnight occupancy restrictions at Weir Creek due to heavy use in the past. Plan this as a daytime soak only.

What to bring

Bring footwear with grip, a headlamp if you may return near dusk, and a bag to pack out trash. Do not assume restrooms or services will be available.

Who it’s best for

This hot spring suits adults and confident teens who are comfortable with uneven terrain and shared soaking space.

Why it’s not marked family friendly

Families do visit, but the combination of rocky footing, crowd variability, and common clothing-optional use makes this a challenging default choice for many families.

Mobility limits

This site is not wheelchair accessible. Pool entry involves stepping on uneven rock with limited handholds.

Setting expectations

Expect a natural creekside soak with changing pool conditions, not a maintained or predictable soaking experience.

Temperature variation

Pool temperatures vary widely depending on inflow and season. Test water before sitting, especially near narrow channels where hot water enters the pools.

Slip hazards

Wet rock and algae create slick footing. Move slowly and keep footwear on when walking near the water.

Respecting closures

Overnight restrictions exist to protect the site and reduce damage. Ignoring them risks further access limits.

Etiquette

• No soap or shampoo in pools or creek.
• Pack out all trash.
• Give others space in small pools.
• Avoid photography of strangers.

Is Weir Creek open at night?
