Plans for walks are constantly being developed. We welcome your suggestions for interesting walks. Maybe you might like to lead a walk. Send your suggestion to: The Streamwalker.

NOTE to leaders of walks who plan to bring their groups to join one of our walks. While we always welcome more people to our walks, it would be appreciated if you would make arrangements with the walk leader well before hand. Adding a significant number of people (eight or more) at the last minute can make it difficult to see that all get the benefit of the walk You can e-mail The Streamwalker and he will attempt to get you in touch with the walk leader so you can make special arrangements.

No charge is made for Lost River Walks. Toronto Green Community and Toronto Field Naturalists provide these and other walks and events as a public service. If you would like to support the work of these organizations, you may join TFN or TGC. Information on joining is provided by walk leaders or you may check their websites: Toronto Field Naturalists or Toronto Green Community.
