The first cache in the series can be found along the border of Graydon Hall Manor. This 1936 Georgian stone mansion is now a luxury event venue but was once considered one of the most prestigous homes in Toronto. When the parklands surrounding the manor were sold, some large apartment buildings and a collection of homes replaced an expansive green space and hunting lands. Now the manor is surrounded by buildings and not visible from the street any longer - you would not even know it is there without the signs.
The cache is a nano so bring your own pen. No need to go onto the property to find the cache and parking is a little hard to find but available on the street at specific times. TTC is also available a few feet away.
