There is a wonderful multi-use trail called the Tiny Beaches rail trail, running north just outside Elmvale up to Penetanguishene. It is a snowmobile trail in the winter, and a great biking, running, and hiking trail in the summer and fall (there are LOTS of bugs in the spring...).

Here's a short video of a few sections along the northern end of the trail from July, 2009.

You can see more details on our hike page, which is located here. Here's the video from Vimeo:
