This is not a "blog" in the sense of a daily journal but a place for me to post GPS trail maps of mountain biking and hiking trails, particularly but not exclusively, in the western Greenbelt in Ottawa, Ontario.

Date codes do not reflect actual posting dates but are manipulated to allow me to order the posts in a thematic order.

Please note that images, maps and photos, will be displayed in reduced size. To see the enlarged images click (or multi-click) on them.


Trails 20, 21 & Untrails Trail System

Dedicated to the memory of Andy (FaustCan) who introduced me to The Untrails

These trails are accessible from Parking Lot P4 on Haanel Drive, although I usually ride to them on the Trans-Canada Trail (TCT). I would describe these trails as being at the low end of intermediate level trails, except for portions of the The Untrails that are more technical. The terrain is varied including a climb from the TCT up to P4. Trail 21 includes board walks over wet areas and forested areas, as well as sections over grassy areas.

Trail 21 used to be divided into Trails 21 (west of Haanel Drive) and Trail 22 (east of Haanel Drive) but they were combined into one trail a few years ago when the NCC consolidated trail numbers and transferred some to trails without numbers. Trail 22 does not seem to have been used anywhere else.

Trail 20 is very wet and not rideable for most of the riding season. It normally does not dry out until late July or August and then does not recover well from rainfalls during the fall. I usually avoid it.

A loop of Trails 20 and 21 is one of our favourite winter cross-country skiing routes, starting at P4 and going down the south side of 21, taking the Trans-Canada Trail (TCT) to Trail 20 and along it, then looping back along the TCT to the north side of Trail 21, and then adding in a loop of the upper portion of Trail 21.

The Untrails

The Untrails are a group of unofficial trails west of Trail 20 and north of Trail 21. A wide section of trail connects Trail 20 to Trail 21 after which you can go straight across and connect to the Old Quarry Trail system across Robertson Road.

However the most interesting part of The Untrails are the single track trails west and north of the wide trail section. These trails were referred to as The Untrails because originally they were very rough and, to me at the time at least, not particularly fun to ride. The trails have now become worn in and were actually quite enjoyable to ride when I rode them to track and add to the trail system map. The portion closer to 28C at the southern end is more technical.

An interesting feature along the wide portion of The Untrails are the ruins of an old homestead (see map), While this does not seem to be preserved in any official way please be respectful of it and other such ruins that are located along the trails in the Greenbelt.

If you do download the gpx file please email me at and let me know so that I have an idea of how many people are downloading and using the files.

I hope to add photos or slide shows to each of the specific trail sections above in the future.
