Hallstatt - other options

Absolutely well worth the trip. I guess it depends on "your time frame"?

We have a day, possible a night

If you drive it’s 1h 30m. If you take a train it requires a transfer making it less convenient. However, parking can be a bit hectic.

Sorry, I didn’t mention we won’t have a car travel by public transit

We really enjoyed St. Wolfgang. It’s easy by public transportation: take the bus to St.Gilgen. Walk to the lake edge and take the boat to charming St. Wolfgang. We actually enjoyed it more than Hallstatt.

It’s easy by public transportation: take the bus to St.Gilgen.

This bus (#150) continues to Bad Ischl which will be one of Europe's Capitals of Culture in 2024.

This town is worth visiting. It became famous in the 19th century when Emperor Franz Joseph I. spent his summer holidays for 50+ years there. Not only for him and his family, but also for his entourage and other nobles adequate villas and mansions were built, a theater, and all other infrastructure (train line, etc.).

If you like sweets don't miss the unique opportunity to eat/buy a Zaunerstollen.

Form Bad Ischl you have an easy train connection to Hallstatt.

Honestly, there is nothing like Hallstatt. I find St. Wolfgang to be a poor substitute.

Hallstatt is pretty cool. Nothing much else like it. Doing an overnight would give you the opportunity to see the town without huge amounts of fellow tourists. Plus, since you will be on public transport, the ferry ride over is lovely.

Go early in the morning by train and spend the day and night. Leave whenever you need to the next day. I find the early morning and evening obviously the best time to walk the village and take pix.
