The Atlas trail sits out from the rest of the Blue Derby trails and deserves trail notes all of its own.  Billed as a white-knuckle roller coaster ride, it is one heck of a track and worth the effort of riding it (just don't think that it's all downhill).  You can ride Atlas as part of a loop, organise a commercial shuttle through Vertigo MTB (I've done this option and highly recommend it) or organise your own shuttle.  These trail notes are written to help you with all these options.

The Big Chook is one of the trails making up the Weldborough section of the Blue Derby Network.  It follows the old Blue Tier Descent route up from Weldborough for the first 3kms and then turns off and what follows is one of the most awesome sections of trail in Tasmania.

One of the original mountain biking trails in the Blue Tier area (and now largely superceded by the new Blue Tier trail built as part of the Blue Derby network) you can ride the Blue Tier descent in several different ways, but at its heart the descent consists of 11km of old school technical trails connecting the deserted town of Poimena and Weldborough

The trail isn’t for the faint hearted, and inexperienced, but those who have a good level of riding skills will find some great technical riding amongst some beautiful forest and heathlands.

There is a dense network of trails criss-crossing the Kate Reed Reserve and it really is best enjoyed by pointing your wheel down the main trailhead and just exploring.  For those looking to push themselves there are some dedicated tracks available and families with kids could equally enjoy riding down to the duck boarded area and just exploring.   Basically get in there and enjoy yourself.  This park has something for all levels.

I'm breaking the rules on this one and listing a track provided by Forestry Tasmania that I haven't ridden.  What I can tell you is this circuit is legal, that it appears to be mainly on gravel roads and fire trails and that it circumnavigates Mount Cameron in the North East of the State.  The recommended starting point on the map provided by Forestry Tasmania is the Scottsdale High School Mount Cameron Field Study Centre (or more specifically the Field Centre Gate) but I could also recommend starting at Little Blue Lake just north of Pioneer on Gladstone Road (B52) for those who don't want to do the extra driving to the Field Centre.

Mt Stronach is a great ride for cyclists with reasonable technical riding skills who enjoy their climbing and descending. You'll gain and lose up to 340 metres in altitude (or 280 metres if you only go to the end of the 4WD track rather than the trig point), but if you're confident on your bike it is worth every pedal stroke, even if you have to push your bike up the first section.  It's really fun riding with a pretty nice view (and rock play area) at the top to make it all worthwhile. Having said that I'm slow and not that good a rider, and I still really enjoyed this trail, it just took me a lot longer.

There are big plans for this area in the future, but this ride just describes what's there today.

This 26km rail trail follows an abandoned railway line between Scottsdale and Billycock Hill weaving its way through lovely farmland and a bit of Scottsdale industry for the first 10kms and then some amazing cuttings and forests as it winds its way up Billycock Hill for the final 16km. With occasional glimpses out over the valley below, and a bit of well interpreted history lying on the side of the track this trail makes a great ride from those just looking to do a few kilometres with the kids through to those willing to tackle the full length out and back.

This short ride follows a section of the Tasmanian Trail from Railton to Sheffield and is on an old railway line for most of the way.  As such the trail makes for fairly easy riding as it passes through surprisingly pleasant bushland, plantations and farmland.
Railton and Sheffield make great places to explore, as do Sykes Sanctuary and Stoodley Plantation along the way.
