Dynamite Boulder is a bouldering area in Grandad Bluff Park, a city-managed park in Wisconsin. It sits among a cluster of climbing areas, with Donkey Punch Wall, Mushroom Wall and Adidas Wall all about 0.1 mile away. The park's city ownership makes it an easy stop for climbers already exploring the Grandad Bluff area. The climbing here is all bouldering, with five routes spread across the V1 to V3 range. Bump and Grind and Dynarête are both V1-2, and Dynamite Traverse is the hardest at V3. The names of the routes add a touch of humor to the boulders, with Illuminati Dynosaurs and TNT Shuffle among the options. Summer is the most comfortable time to visit. Typical averages from a nearby weather station in La Crosse show July highs around 80°F with lows near 62°F, while January highs average only about 24°F. For more time on the park's trails, Vista offers mountain biking about 0.6 mile away, and Stinky's is a hike roughly a mile off. Paddlers can reach the Goose Island Canoe Trail about 6 miles away.
