This is a popular picnic area just south of Burnie, near Ridgley. An easy walking track to the base of the two-tiered falls is a few hundred metres upstream. The road continues to the top of the falls and an accessible viewing platform. A walking track leads you through the thick undergrowth of the riverside, down to a grassed area at the bottom. There are barbecues with picnic tables at both the top and bottom of the falls; a beautiful place to spend the day in summer.
Pittoresque hike and alpine feel, suitable for everyone with plenty of photo spots and fantastic picnic options by the lakes. Watch the weather.
A walk in Hastings Cave State Reserve to the entrance to Newdegate Cave which can be explored on a payed tour.
A walk that you must pay for entry to the thermal springs to do. You get to experience a cold creek and a slightly less cold creek.
A walk from Peoples Park following Botanical Creek to Hogarth Falls.
Challenging track with steep sections , scrambling over boulders and crossing the Western Creek waterfall makes for a very fun hike. Do NOT attempt this one if you are unfit, inexperienced or ill-prepared. This is for the more serious of hikers/walkers.
A short walk following the Junee River to the Junee Cave mouth. Which is part of the Junee-Florentine karst area and is connected to Australia's deepest cave in the Niggly/Growling Swallet cave system.
A short walk exploring the historic Kangaroo Point Battery.
