Trail Maps

Trails at the Humber Arboretum vary in their difficulty and accessibility. Near the main entrance at the back of Humber College, level and gently sloping paths are made up of interlocking stone and hard-packed gravel that can take you through the ornamental gardens. By entering the forest near the gardens, you can enjoy the level trail of the upper forest loop. Venture down wooded slopes and stairs to explore the lower forest, meadow paths, and to connect to the paved trail along the Humber River. 



With so many different habitats, the Humber Arboretum is a year-round home and migratory stopover to wide number of bird species. Look for woodpeckers and owls in the forest, swallows and hawks in the meadows, herons and egrets in the ponds, and ducks along the Humber River. Start with a visit to the Arboretum's Bird Garden for a close look at sparrows, finches, winter juncos, and friendly chickadees.

Using free platforms to record the wild species you encounter during your visit, you can help contribute to our Humber Arboretum Atlas iNaturalist project and our eBird hotspot species lists. Or you can support native bee research, track and clean up litter, and more.

Tree Caching

As you walk through the forest, keep your eye out for QR codes attached to 16 different trees. Scan the code with your tablet or smartphone to not only learn about the species of tree, but also the positive impact the individual tree you’re looking at has on the environment! The most recent measurements of the tree are used to estimate the amount of carbon stored in the tree. TreeCaching Trails are a project of ACER/ClimateSake.

Look for American beech, blue beech, sugar maple, hickory, ironwood, and white ash as part of the TreeCaching Trail here at the Humber Arboretum. You can also find other TreeCaching Trails through ClimateSake’s website.
