8km out and back track from Kingston to as far as we get, maybe the shot tower.
Meet at the Browns River Pedestrian Bridge at 8:50am.
Greater Hobart Trails has this to say.
"The route followed by today's Alum Cliffs Track has long been a coastal path used by local people. In 1988 it was formally developed as part of Australia's Bicentennial celebrations. In more recent years, Council has upgraded the southern section of the track, which climbs from Tyndall Beach through coastal blue gum forest with tall silver banksias. The track then winds up through silver peppermint bushland, dips into a glorious fern-filled gully, before rising again onto headlands for commanding views over Storm Bay and the Derwent Estuary. In 2016 Council completed the extension of the track from the historic Shot Tower to Wandella Avenue which then links in to the Taroona Foreshore Tracks if you wish to do a more extended walk. The track provides an 8 km return trip, and the beginning of the track provides toilets, picnic facilities and parking with nearby Cafes at Kingston Beach. The track connects with the Brickfields Track and also can be linked with the Boronia Beach Track via a short stroll along Kingston Beach."
