Rosecliffe Farm Cottages borders Woondum National Park via the conservation area, and it's accessible right from the property via the Noosa Trail Network, or by vehicle if you'd like to explore further into the park.
Woondum National Park is a beautiful stretch of subtropical rainforest with spectacular rocky creeks, and can be explored on foot, by mountain bike or on horseback. If you have a 4WD, there's a track through the park leading to the Mothar Mountain Rock Pools, where Woondum and Boulder Creeks meet, a lovely spot for swimming among the granite boulders. Wood-fired BBQs are available for a day out (bring your own paper and matches).
