We start in Mariazell and drive on the B20 in the direction of Mitterbach, but in St. Sebastian we branch off onto the Erlaufseestraße. Shortly before the Erlaufsee we keep right and drive along the Seestraße to Mitterbach. At the crossing to the B20 we keep left and shortly after the Erlaufstausee in Mitterbach we turn right in the first bend onto the forest road (marked "Hubertussee-Runde"). After the Schindelsattel (ascent) we ride a short downhill and then turn right into the Sonneck-Runde (marked). First comfortably, then rising again we reach the Sonneck, here we have a wonderful view of the Gemeindealpe and the Ötscher.

We stay on the forest road and come to the Habertheuer (left turnoff to the Bürgeralpenrunde), drive through the Habertheuer settlement and come back to B20 in St. Sebastian. Keep left here and shortly after the ÖAMTC turn left again into Wiener Straße, which takes us directly to the main square.

The tour can also be started in St. Sebastian or Mitterbach. If you don't want to cross the Erlaufsee, take the B20 directly to Mitterbach.

This tour is passable in both directions

A few more requests - the nature and wildlife will thank you and the bike experience will be an even more beautiful: 
  • Please stay on the designated paths!
  • Please do not leave any litter!
  • Hikers and pedestrians have priority!
  • Please ride responsibly and in half-sightedness!
  • Please ride only a technically perfect bike!
A few tips for safe mountain biking: 

Check your bike's air pressure, spoke tension and brake pads after every tour.

The helmet is part of every mountain bike tour.

Consider in advance what equipment you need: warm clothing, rain and wind protection, repair kit and first aid kit belong in your backpack, as well as a charged cell phone.
