Underbelly Boulder is a bouldering area in Minnesota's Baptism River State Aquatic Management Area (Lake), managed by State Fish and Wildlife. It sits within the state's aquatic management area, and its name points to the bouldering rather than a route or a peak. The climbing here is all bouldering, with six routes spread across the V2 to V6 range. The easiest is Inny or Outy at V2, and the hardest is False Hopes at V6. The area is close to several other climbing spots, including Picnic Rock and Sawmill Creek Dome, both within a mile. Summer is the most comfortable time to visit. Typical July highs reach about 76°F with lows near 54°F, based on averages from a nearby weather station at Wolf Ridge. Winters are cold, with January highs around 19°F. The Superior Hiking Trail passes just 0.3 miles away, and Finland Glade is 0.8 miles off. For more climbing, Section 13 is about a mile away, and High Falls Trail - East is roughly 4.6 miles away.
