Writing-on-Stone Provincial Park

Writing-on-Stone Provincial Park (Áísínai’pi) in southern Alberta protects a rich concentration of Indigenous rock art carved and painted onto sandstone cliffs along the Milk River. The park combines cultural heritage with a distinctive coulee and hoodoo landscape.

The main attractions are the numerous petroglyph and pictograph panels set in narrow valleys and cliff faces, plus eroded hoodoos and steep-sided coulees that provide vantage points over the river. Short marked trails and interpretation at the visitor centre guide visitors to the principal panels and viewpoints.

The valley has been used for ceremonial and cultural purposes by Indigenous peoples for centuries, and the park was established to conserve both the rock art and the surrounding landscape. In 2019 the site, referred to as Áísínai’pi, received international recognition for its cultural value.

The park sits along the Milk River near Alberta’s southern border with Montana, roughly east of the town of Milk River and south of Lethbridge. The landscape is semi-arid and dominated by exposed sandstone cliffs and dry grassland.

• Extensive rock art: The park protects one of the largest concentrations of Indigenous rock art on the North American Plains, with panels located along a short interpretive trail system.
• Restricted access to some panels: Many rock art sites are culturally sensitive and may be protected behind fences or viewed from designated walkways to prevent damage and respect Indigenous significance.

What to See#

• Rock art panels: A series of sandstone cliffs and rock faces along the Milk River valley that bear thousands of petroglyphs and pictographs created by Indigenous peoples over centuries.
• Hoodoo and coulee landscape: Hoodoo formations and steep coulees carved into the river valley provide notable geological scenery and elevated viewpoints over the Milk River corridor.
• Visitor centre: A small on-site visitor centre offers interpretation about the rock art, Indigenous connections to the landscape, and park guidelines for visiting sensitive sites.

Writing‑on‑Stone Provincial Park is in southeastern Alberta near the town of Milk River, about 150 km southeast of Lethbridge. From the Trans‑Canada Highway (Highway 1) take Highway 4 or local roads toward Milk River and follow signs to the provincial park. The park is accessible by car; nearest larger centres with airports are Lethbridge and Medicine Hat.

• Arrive in the late afternoon to see pictographs change color in the slanting light along the Milk River cliffs.
• Hire a Blackfoot guide through the park visitor centre to hear the Indigenous stories tied to specific panels - many images are ceremonial and locally named.
• Avoid climbing on the rock faces; many petroglyphs and pictographs are fragile and protected by law.
