On a hill opposite the castle sits a city park Monchburg that contain the modern art museum and the ruins of fortification built in 1630 during the 30 years war. Easy access to the park and fortifications is via an elevator that cost 3 euros. On top of the museum, park and fortress Monchberg provides fantastic views over Salzburg.
Hohensalzburg Fortress sits atop the Festungsberg and Moenchsberg Mountains. Many of the most popular sights of Salzburg are to be found nestled into the protective wall of the Moenchsberg. It seems to wrap itself around the city like a gigantic loving guardian.
A decent hike in the area is to work your way from south to north along the Mönchsberg. You can easily incorporate the hike with a visit to the famous Hohensalzburg fortress. To start, you can either take the funicular to the fortress, or you can hike your way up. Exit the north gate and follow the path along the Mönchsberg. There's a hostel along your path where you can have a meal or even stay the night if you wish. Off to the west, there are fortifications offering excellent views in all directions. Finally, as you descend the extreme northern end, you'll find yourself in the neighborhood of Mülln, where the famous Augustiner brewery can be found.
This hill is some 60 meters above the old town of Salzburg and quickly gets you out of the bussle of the city and up into forests and walks that allow you to view both the city and countryside. You can get great views over the old town, view the castle (Festung Hohensalzberg) and the river Salzach.
You can catch a lift up which leaves inside the Musuemsplatz building which has the Musuem der Moderne in part, the other part being up on the hill. The lift operates daily from 9am to 11pm and when we were there, cost around 2.50 Euro. You can also take stairs from Toscaninihof which will take you about 15 mins to climb.
The many walking tracks up on Monchsberg are great, views over the Tyrol and you pass many splendid houses. There are remains of the old city walls, these date from the 13th century.
You can return the way you came, or better still, walk all the way around to the castle and take the funicular railway back down or via the stairs. A very pleasant area.
Not far from the Burgerspital is the Monchsberglift - the elevator that you take to climb the Monchsberg and get a stunning view of the city. The lift operates daily from 9am to 11pm and charges around 2.90 Euros. The rock walls of the 500-meter-high Monchsberg are regularly checked by mountain cleaners or Bergputzern to remove loose rocks and bushes - this is to prevent landslides. The last catasthropic landslide occured in 1669 that claimed over 200 lives.
The Monchsberg is one of the many aerial/panoramic lookouts in Salzburg and is considered one of the best. Enjoy!
One imprtant tip: After paying to get to the lift, you will be given a receipt that will serve as your ticket. That piece of paper doesn't look special at all and it's more like a receipt from the grocery. BUT by all means keep it with you and if possible don't crumple it as you will need it later. Once you're down and ready to leave, you will have the ticket scanned to get through the mechanical exit gate.
Take the lift from Gstättengasse in the Old Town to the top of the Mönchsberg mountain. (For those interested, this is also the home of the Museum of Modern Art.)
The views of Salzburg and across to the Fort are wonderful and you can go for a nice walk around the mountain, through woods, on well-marked paths. On the way, you can visit the 15th Century Mülln Parish Church. You can either do a circular walk back to the lift, walk all the way down or even walk up to the Fort if you're feeling energetic enough.
The road through Monchsberg is a must see and must walk. First, you enter it from old town and you'll walk by the major festival hall on the left and the old horse washing fountain on the right... then walking through it... straight through on the right path or meandering around with shopping on the left. On the other side is another great side to Salzburg that offers terrific cafes and shops. Plus, on the otherside of Monchsberg, after walking out of the mountain, head down a block or two and turn left and walk up the street to the Rainberg hill/mountain. If you look hard enough, you'll find a little walking path that seems to go up to a private house.... the path is actually a public path over Rainberg. On the other side of Rainberg is a nice little town/village and through that village is the street that takes you to Schloss Leopoldskron (about three minutes to your left).
For one of the best views of the town of Salzburg take the so-called Moenchsbergaufzug, the Moenchsberg Elevator. Magnificent views of the Castle Hohensalzburg and the Kapuziner Kloster.
