Left Side is a bouldering area in Connecticut, about 1.4 miles from Center Groton. It sits right alongside several other climbing spots, including the Ledyard Areas, Glacial Park and King & Queen Boulders, all within about 0.1 mile, so it works well as one stop in a cluster of bouldering. The area holds six bouldering routes, all rated from V1 to V7. The hardest are Bryan's Big Day at V6 and El Rey De La Hoja and La Paloma at V7. The median grade is V3, so there's a range of options for climbers of different skill levels. Summer is the most comfortable time to go. Typical averages from a nearby weather station in Groton show July highs around 81°F and lows near 66°F. Winters are cold, with January highs around 39°F and a few snowy days each month from December through February. For a change from the rocks, the Gosa Blue Trail and Gosa Red Trail are both about 1.9 miles away, and the Mystic River offers canoeing roughly 3.6 miles off.
