Answer:
A Hallstatt Tour or A Bavarian Mountain Tour.
The speaker is using allusion it this line.
Allusion is a figure of speech in which something outside of the source text is being referred to. So here, Bacchus, Satan, and the Hangman aren't actually characters in this literary piece of work, but the author is making a reference to them nevertheless.
The effect of the simile in this passage makes the passage more interesting and gives it that extra "boost" to help the reader understand what is going on.
Hope this helps!
