What we're about

We are on Instagram @ravineexplorers

We are a cardio hiking group with a twist….of history! Toronto’s ravines are rich in trails and history. Our 10 km + cardio history hikes aim to not only raise your heart rate but also your awareness of the vibrant history and archaeology of the Don River Valley, and also the neighborhoods adjacent to it. Our new urban hikes are already quite popular and are a great way to explore Toronto.

Rather than hike on by, we catch our breath AND catch up on a few historical tidbits about the area we are hiking in. Sometimes these tidbits of history will be presented by an “expert guest hiker” who will join us, and by me.

These cardio history hikes combine my appreciation for the Don River Valley ravines and trails, my Ph.D. ancient history and archaeology and my goal of staying fit and staying outdoors, year round!

Please note: Only members with a clear profile photos will be added to the "going list" for our hikes. We do not allow guests (ask them to join our group to attend) or pets, and all members must be 18 years and older.

You don’t have to take notes and there are no exams on these cardio history hikes! :). Just show up with a desire to have a great cardio workout, the enthusiasm to learn something about the Don River Valley trails & urban neighborhoods, and an openness to meet other awesome hiking history explorers.
