Sunday Morning Forest Fix

Busy lifestyle, and couldn't fit in mid week exercise ?
This is a fun 3.5 hour walk along the BibbulmunTrack. We will walk there and back of no set distance, walking at a constant pace of 4.5kph plus (no stopping).
I anticipate a distance of 15+k and after we will go to the Kalamunda markets for a relaxing look around, coffee or breakfast.
