McKell Park is an oasis of Sydney beauty at the tip of Darling point with stunning views of the harbour city and Clark island. The former site of the historic Canonbury residence, during WWII the park was also the site of the Royal Naval Hospital. Today it is a hidden gem known only to local residents using the ferry service and to those who want an idyll spot for a late afternoon picnic, soaking in the sights of the city. The park is only open 7am to 7 pm so the cache is located slightly outside the park. Try and come during opening hours and spend some time exploring and relaxing. The cache itself is camoflaged but should be fairly easy to spot.
