If you go the Gisborne side, yes you will find bog holes etc. if you want some easy/med stuff and explore a few mines, the Blackwood/Daylesford side is the go. Plenty to look at around there. I camped out there Sat night, did a little exploring......
Yes plan is to go mine exploring around Blackwood side, probably go to Colbrook reservoir, duke mine, easter monday, morning star etc...
