Big Bay is a climbing area in Michigan, about 3.3 miles from the town of Alder. It sits among a cluster of climbing spots in the Marquette area, with several other crags and bouldering areas within a couple of miles. Summer is the most comfortable time to visit. Typical averages from a nearby weather station show July and August highs around 75°F with lows in the mid-50s, while winter highs stay in the 20s. The closest climbing neighbors are Secret Crag and Marquette (and Central UP) Bouldering, both about 1.7 miles away, and AAA Wall at 1.9 miles. In winter, the Hidden Grin Loop cross-country ski trail lies about 3.8 miles off.
