while im leaving from salzburg for the day trip, i'd like to arrive at the end of the day at vienna and thus will have my bag with me. I'd like to go to the Dachstein ice cave in the morning, preferably when the funicular opens at 8:40 AM so that way i can make the best of very limited time. Does anyone have experience arriving to Hallstatt from Salzburg using public transportation, specifically with an effort to go to the Dachstein ice cave as early as possible?
from my research it seems like there are two ways to do this using public transportation from salzburg
bus; take 150 bus from Salzburg to Bad Ischl, 542/543 bus to Dachstein Caves. Looking at bus schedules though, it seems earliest but gets to Dachstein caves would be 9:12 AM. I would then leave my bag at the bag storage at the ice cave to pick up afterward and then take with me into town
take 5:12 train from Salzburg to Obertraun which arrives at 7:34 and then take taxi from there to the funicular. This will involve an early wake up but i can leave my bag at the Attnang-Puchheim station and then pick it up from there on my way to Vienna on the 18:22 train.
Anyone ever try either of these and have any advice? Especially if the train is mandatory to arrive at the funicular by 8:40 or if the bus can pull that off also.
