Blueberry island is a tiny island located on Seaver pond where the vegetation seems to be almost exclusively blueberries.
The reason for the high terrain rating is that access will require a kayak, canoe, boat or a very long swim.
It may be possible to walk across the ice to it in Winter but not without some inherrent danger!
It is possible to walk along the shoreline to it but that will require crossing private property for which I purposely have not sought permission.
That would be a significant walk and require bushbashing - something I am not in favour of.
Have fun, be safe and enjoy the berries - if they are in season.
Congratulations to Geokopp on his FTF!
