Plenty of good places around here to ride.
Beechworth MTB park has a great 10km XC loop. Flametrees is another local trail that is on flatter terrain, around 7km (but growing all the time) of fairly flowy track around the Rail Trail between Beechworth and Everton.
Just outside of Wang is the Warby Ranges - there is a decent 3.5km loop around Wenhams Camp.
Albury Wodonga has Nail Can Hill, Bright has plenty of trails and Mt Beauty MTB Park is less than an hour and a half away.
Then there are a bunch of lesser known tracks that social rides with the local MTB groups will alert you to.
Feel free to PM me if you're looking for someone to ride with.
