From the end of Mt Riddell Road, Healesville, follow the well formed track up to Mr Riddell 600m ascent.  

Approx 14 km  Medium 3 hours return.

A steady uphill climb for 6km on well-formed tracks, followed by a flat walk to the cairn. Return by same route.

Mostly not too steep but the last 1.5km before the top are quite hard work. 

It's about a 45 min drive from Eltham.

Meet at the rough parking area on the dirt road at the very end of Mt Riddell Rd.  It's  just off the edge of 278 K2/3 on Melways.
