Gold Coast Hinterland
You can get a map from Gold Coast Mountain Bike Club website (www.gcmtb.com.au) – and it is only open to ride for events but it is about 30km, just under half an hour, from central Nerang, about 42km from Surfers Paradise. It's not hard to find, but it is on a minor road in an out-of-the-way valley.
I pinched this write up from the Australian Cyclist website (www.australiancyclist.com.au) – hope they don’t mind but they explain it perfectly.
Illinbah has two DH options, which are known as A-line and B-line. Both start as one, are 2.3km and cover an elevation of 520m. From the base-camp racing village there are shuttles to the start, with buses for riders and trucks for their bikes.
The track starts with descending, flowing switchbacks. Dropping through a 200m rock garden, then descends and twists out into open grass and splits at 220m elevation.
A-line becomes a series of high-performance rock drops and tight single tracks. Advanced skills are needed here: some of these drops are really cliffs and there becomes a fine line between cycling and falling. Some riders find their bikes shy at the rim and they can go no further.
B-line is a more fun, flowing ride with small rock gardens, berms and switchbacks and the two meet up just above the major booster bridge.
This is a masterpiece of solid carpentry that marks the first visibility of riders to those below in the race village. And the faster you take the bridge, the higher in the air you will be when you are first seen.
From the bridge there is a 200m descent: major 75ft pro-line jumps lead down to the novice riders' switchbacks and the race village.
