If you follow the tree line about two miles north from Drummond Island
you will see the entrance to Harbor Island on your right. Although I do
not recommend this for the average snowmobiler you can ride into the
lagoon through the small entrance shown top.
The Island it self is off limits to sleds but
you can ride around the lagoon. Because the
lagoon is protected from the heaver winds the snow tends
to settle here and get very deep. Getting stuck can be a
problem for many sleds. The view below is headed out the same
entrance west to the tree line.
