Glacial Park is a bouldering area in Connecticut, about 1.4 miles from Center Groton. It sits among several other climbing spots, including the Ledyard Areas, Left Side and King & Queen Boulders, all within about a tenth of a mile. The park's climbing is all bouldering, with six routes spread across the V1 to V6 range on the V scale. The most comfortable months for a visit are late spring through early fall. Typical averages from the nearby Groton weather station run from highs around 66°F in May to about 81°F in July, with September easing back to the mid-70s. The routes include Blaze Boulder at V1 and Sid the Sloth at V6, with Power Pony at V5. The Gosa Blue Trail and Gosa Red Trail are both about 1.9 miles away for a walk, and the Mystic River, about 3.6 miles off, offers canoeing.
