I am fortunate that Marc Durdin who runs a blog in Tasmania has allowed me to post some of the climb reviews that he put together around Hobart.
Grasstree Hill is located on the Eastern shore of the Derwent River. Behind the suburb of Risdon Vale. It is a category 3 climb, with a smooth and constant 5% gradient which is ideal for a tempo climb. The road surface is in good condition and is quite smooth. Unlike many climbs in Hobart. The climb forms part of a popular cycling route to Richmond in the Coal Valley. Many riders do a loop over Grasstree to Richmond and return south over Tunnel Hill or north via Brighton.
The western side of the climb is sheltered from many of the winds of Hobart. Hence is a pleasant climb at almost any time of the year. It gets sun quite early despite being on the western side. Thus is a great route for an early morning loop before work.
The eastern side has a bit more variance and is considerably more exposed to wind. The corners are a bit sharper, the road feels a little less smooth, and the gradient is a little less constant. Even without spectacular views that are a feature of nearly every other climb in Hobart. It is still an enjoyable ascent.
Grasstree Hill is also very popular with motorcyclists. Some of whom travel considerably above the 60 km/h speed limit.
Both sides of the hill make for a great descent. Not overly fast at 5%, but with little need to touch the brakes at almost any point.

GRASSTREE HILL (SOUTH APPROACH)
|TIME FROM CITY||40 minutes|
|How to get to the climb: From the Cenotaph, ride north on the bike track until you reach Elwick Road. Turn right, ride to the end, then dogleg right onto Goodwood Road. Follow this road about 6.5 km to the base of the climb (straight through the roundabout).|
