Hey mate, a good beginner loop would be Buckle, Upper Buckle, Dog pound, Middle, Red gum, Hug and Blair. Along these trails you’ll find b lines around any features, so you’ll be fine.
This loop will cross lots of fireroads. If you need to bail out, take any of the fireroads down to Lake Circuit. This is the fireroad that goes around the lake.
Have a copy of the trail map on you.
Hope you have fun.
