Conrhenny is a triangular planation just outside Onchan. Originally planted with Pine and Spruce in 1968 plans are in place to grow more broadleaf trees. More than 5,000 trees have been planted by local primary school children in the last ten years. A great place for children to learn about nature. The woodland is used each year for the Longest Day Longest Ride competition and has a well defined cycle track as well as other trails. The carpark at the beginning of the cycle trail is a wonderful spot for stargazing.
