No special access issues
1) As per usual: !Don't block other cars! on the parking lots and never park in non designated areas.
There are plenty of parking spaces available there is usually at least one somewhere, if all are full just, above Zirl in the direction of Ehnbachklamm there are some more (not free).
There is a 'Bathroom' close to the parking of the ÖAV-Klettergarten.
2) From the A12 take exit onto 177 in direction Zirl/Seefeld, then shortly after crossing over the Inn river take the first right off of 177 onto 171. Head left onto 171 (away from Zirl towards Innsbruck) after 50m the Dschungelbuch Parking will be on the right the crag to the left. All the Parking lots are free and clearly labeled.
3) Be careful when crossing the road 171 heading along the bottom of the Martinswand, cars tend to drive quite fast! The approach takes from 3 min to 40 min depending on if you are going to Dschungelbuch or Galerie. Stay on the paths and be careful not to fall on you way to the Grotte or Galerie. Check the map to find the best suited parking lot for the sector you want to visit.
Grotte; park at Dschungelbuch, cross the road then walk left along the road and head up behind the barricade towards the Ehnbachklamm. Alternitively park at Ehnbachklamm but the parking lot is not free.
Galerie has a steel ladder to get on top of the train tunnel, on top of which the sector is situated. Take care when climbing it! To get to the right part of Galerie you can use the anchor to rappel off of the train tunnel.
Supermarkt is the furthest East and you need to park at ÖAV- Klettergarten and walk along the road all the way to the fence of the bio wast station, then right before it head up the stairs and along side the fence.
All the other sectors are very straight forward to get to, Enjoy!
