I visited the Olinda Forest on 18 June 2010, 30 km east of Melbourne town - another bleak and muddy day!
From the small car park at the junction of Stonyford Rd and the Olinda Creek, I followed Management Road 18 to Road 13, then descended to the old bridge over the creek, and returned.
The creek was flowing strongly - there were many beautiful colored fungi.
This hike was about 3 km return.
