Many Canberra nature reserves have been reviewed on Australian Hiker.
When we discuss obstacles to cycling, it is often meant figuratively, but not in this post. As a cyclist, many barriers are placed in our way.
Cycling is permitted in 30 of the Canberra Nature Park reserves. Information from the Management Plan 2019 can be found in OpenStreetMap. The rideable reserves are previewed here.
Throsby, Gungahlin, has an excellent bike path and views of the Goorooyarroo Nature Reserve.
