The walks here are well signposted with times that assume a reasonable level of fitness, maps show either a continuous red line (a trail OK for biking), a dashed red line (lake district style path) and a dotted line (you'll need to use your hands as well) and a ladder symbol (rock climbing gear needed). Trails are marked with red and white painted marks and red dots and are numbered so in most conditions its very difficult to get lost. There are cafe's and bars (Hutte) all over the place so with a little planning you don't need to carry much food and can enjoy a meal with beer at almost any altitude and prices are reasonable seeing as someone (or someone in a helicopter) has to cart all that beer up the mountain.
Warning - there are several popular brands of map, Freytag & Berndt are popular but the contour lines are shown at 100m intervals with no heights marked on the contour lines and no relief shading either so what might look like an Alpine Meadow in fact turns out to be a near vertical slope of 1000m + !
The Kompass 1 :25000 and 1:50000 maps are far better for visualising the terrain and more accurate, they are on sale widely and the map for this area includes an english language booklet as well.
