You'll be looking for a magnetic micro geocache that shouldn't be too difficult to find. The biggest challenge of finding this cache will be the muggles since it can be a high traffic area.
Muskoka Wharf is 89 acres which is partly parkland that's also port of the Segwun and Wenonah II. The Segwun was built in 1887 and is North America's oldest operating coal-fired steamship.
Muskoka Wharf is also an area where summer and winter festivals are held such art and craft shows, boat shows, a rib festival and a weekly farmer's market.
Enjoy!
