I've never taken a bike into the camping area and I never will, I've seen too many bikes being dragged out by tractors to wreck something I need to ride 1,400 miles home on.
We've always parked as near to the imbis at the top entrance as we can then walk down to the main entrance, walk back up with a bale of straw and then pitch our tents in the field below the imbis. It makes it easy to walk down the road to buy firewood, easy to buy food and alcohol from the imbis and it's only 10 minutes walk down to the amphitheatre at the bottom. We always stopped at the same spot and met up with a group of guys from Frankfurt then shared a fire with them.
We'd get through at least €200 worth of firewood at €10 bundle and had some great laughs launching Chinese lanterns which the Germans would allow 30 seconds of free flight before launching rockets at them with a couple of cases of beer being the prize on offer for the winner depending on if we got more away than they shot down.
Snow is good, ice is good, rain turns it into a swamp that leaves you simply wanting to go home to escape from the misery and you've not lived until you've been sitting in the portaloo trying to ignore the smell only to realise that someone has piled a load of straw around the door and set fire to it
