Cairn Cave is a bouldering area in Massachusetts, about 1.4 miles from South Foxboro. It sits among several other climbing spots, with Phantom Tower and The Nose Boulder each about 0.1 mile away, and Pine Tree Boulder at a similar distance. The climbing here is all bouldering, with five routes ranging from V1- to V4, so it works well for climbers who want to focus on short, crag-style problems. The most comfortable months for a visit are late spring and early fall. Typical averages from a nearby weather station in Walpole run to highs around 70°F in May and 74°F in September, with July the warmest at about 83°F. The closest trails are the Acorn Trail, about half a mile away, and the Healthy Heart Loop, about 0.6 mile off. For a change of pace, Lake Pearl offers fishing roughly 3.6 miles away.
