The Slab is a climbing area in Keller-Kirn Park, a city-managed park in Ohio. It sits on city land, and several other climbing areas and trails lie within a short distance, making it easy to pair with other outings in the park. Spring and fall are the most comfortable times to visit. Typical averages from a nearby weather station in Lancaster show May highs around 74°F and October highs around 66°F, with September and October seeing the fewest wet days of the year. The Amphitheater, Flat Rocks, Upper Lunch and Lower Lunch all sit about 0.1 mile away, and the Quarry Trail is also close by.
