This cache involves a great walk through mangrove swamp on a boardwalk. The cache itself should be fairly easy to find and retrieve. The aim of this cache is to bring you to a great spot.
Buffalo Creek Reserve is between the Lane Cove National Park and the Fields of Mars Reserve. There's a lot of bushland and parkland around here, and a fair few caches.
Buffalo Creek Reserve itself comprises a a playground and a reserve. For more details see the website: Fields Of Mars.
The cache site can be accessed either from Buffalo Creek Reserve (very kid friendly) or via the Lane Cove National Park from Pittwater Road (nice walk). No need to leave the boardwalk or do anything risky to yourself or the surrounding environment.
Cache has a log and should have pencil, but best to bring your own pen. Please be very careful when replacing the cache that it is properly attached. There is room for small items.
(Note that this is the second incarnation of this cache. I archived the first when it went missing at a time I could not maintain it. The previous version moved several times, so for some finders this will be new, but for others it will not.)
