Interstate Park comprises two adjacent state parks on the Minnesota-Wisconsin border, both named Interstate State Park. They straddle the St. Croix River, a deep basalt gorge with glacial potholes and other rock formations. At the end of the last glacial period 10,000 years ago, torrents of water flowed south from the melting glaciers, carving the St. Croix River Valley. The soft Cambrian sediments were easily eroded into a wide valley, but the hard basalt was resistant to erosion and when it reached the hard basalt floor, the river was channeled into a deep, steep-walled gorge, which makes for some fabulous climbing opportunities.

Climbing Routes

Cave Boulders- The Cave Boulders consist of two over hanging boulders one higher on the hill then the other, with the top out for the Bottom boulder being the flat space in front of the Top boulder. The Top boulder is the steeper of the two, and offers the most challenging lines.

  • Big Boy- V2-3
  • Cave Direct- V2-3
  • Cave Traverse- V8
  • Midget Sit- V7
  • Midget Stand- V5
  • Oxygen Cocktail- V9
  • Pharaoh Arete- V5
  • Pharaoh Right- V3-4

Indian Head- A small cluster of rocks just outside a wooded area. Quiet and serene, these climbs are worth the trip. (Traditional Climbing)

  • Little Wing- 5.4
  • Air Conditioned- 5.7
  • Heat Wave/Layback Crack- 5.8
  • Indian Head- 5.8
  • Mantrap- 5.10c/d

Mike’s Boulder- This slopey boulder holds two of the most difficult problems in Wisconsin.

  • Mikes Left- V7

Picnic Area- Wonderfully shady and relaxing, this area holds quite a few nice warm ups. (Traditional Climbing)

  • Picnic Crack Right- 5.8+
  • Pine Tree/ Picnic Face- 5.10a
  • Rock Dove / Picnic Crack Left- 5.6

Picnic Rocks- This little cliff has two fun climbs.

  • Lichen It?- 5.9
  • Picnic face- 5.10+

Sentinal Area- This cliff is located in a highly forested area and offers respite from the sun on hot summer days. This is a smaller area but contains a high percentage of quality crack climbs. The lack of beginner climbs and the somewhat exposed approach make this a less than ideal spot to bring beginners.

  • Lost Eagle- 5.8-
  • Lost Ego- 5.8+
  • Prow- 5.12a
  • Sentinel Crack- 5.10a
  • Stay Hungry- 5.10b
  • Yosemite Crack- 5.10a

Tiny Bubbles Area- The majority of the Basalt within Interstate Park is characterized by a smooth, and sometimes glassy surface. However, not all the rock has been polished by the St. Croix River. The Tiny Bubbles area is a perfect example of high quality texture found within Interstate Park. The vesicular texture is formed when a gassy igneous rock cools, trapping these bubbles within the rock.

Talus Field Boulders

Tiny Bubbles Wall

  • Sound the Horn- V0

Wisconsin Strip- This obvious cliff on the Wisconsin shore of the St. Croix River is the farthest north area on the Wisconsin side of Interstate State park.
