There are OpenStreetMap updates for both Mount Mugga Mugga Nature Reserve and Isaacs Ridge Nature Reserve. Unfortunately, no new paths come out of it. One route is now closed down to Mugga Lane as a result of new fencing along Old Quarry Road. Big trucks come labouring up this hill all day long. More about the changes below.
There have been many small changes and a few major ones. The information on canberra.bike is correct and the maps on this page have been corrected.
Isaacs Ridge Nature Reserve
Isaacs Ridge Nature Reserve wraps around Long Gully Pine Plantation. It is much bigger than was shown on OpenStreetMap before the updates (see below). Isaacs Ridge Nature Reserve’s edges are on Mugga Lane and Long Gully Road. There are no management trails in this section but it could be walked. The gates between Isaacs Ridge Nature Reserve and Long Gully Pine Plantation are open.
Canberra Centenary Trail
The ACT Environment website still shows the Canberra Centenary Trail going around the south of Mount Mugga Mugga, which is actually fenced off. You cannot go that way. The current route goes north of Mount Mugga Mugga. OpenStreetMap has been updated to reflect that.
Section 7 – Tuggeranong Town Centre to Parliament House page of the ACT Government Canberra Centenary Trail website is yet to be updated. I have written many emails since December 2018 requesting corrections to this website. A question has been submitted to Minister Steel in the ACT Legislative Assembly in 2019. In a standard answer, he denied any problem, but to be fair he may not be the right person to ask. The challenge of trying to find who is accountable for the Canberra Centenary Trail remains as it wanders its way across directorates. Do not trust the Canberra Centenary Trail website. Trailforks is more likely to have the correct Canberra Centenary Trail ride alignments as GPX files to download.
Whats is Trailforks?
For those that do not know Trailforks, it is not a map but a collection of trails that mountain bikers have ridden and uploaded in the GPX file format. A GPX file contains a trail of digital breadcrumbs for the ride. The concept of crowdsourcing trails is known to us from Strava. Strava generates “heat maps” to show where people like to ride. Trailforks takes a notebook approach. The page for a trail is updated and maintained in a database like a well-tended garden. The Trailforks trails are superimposed over a map. Which map depends on the app you use. Garmin GPS bicycle computers use OpenStreetMap.
