Hi Andrew,
our local repeater in Salzburg is on 145.6785 (-0,6) with 88,5 Hz Subtone. The repeater is located on OE/SB-268 “Gaisberg”. The Gaisberg is even accessible by car (24/7, toll-free) and offers a panoramic view to the Salzburg area. Sure not the perfect SOTA summit but ideal if you want to see much of area with less effort in a very little time.
Some local hams (including me) are qrv on 145.475 simplex CTCSS 88,5 Hz.
Just drop me an email (oe2gxl@oevsv.at) in case you want to crosscheck your plans or need assistance.
73 and enjoy your time in Salzburg
