I originally booked the tour via train, but AB Poland reached out and offered riding in a passenger van with free lunch instead. I took the van.
The tour itself was amazing, and the tour guide was knowledgeable and thorough. The driver, Wiktor, was also friendly and I learned so much that day.
As a young student, the price made me a bit weary, but it is worth every penny (and then some!)
Highly recommend, and next time I'm in Poland, I'll be sure to book a different tour with the same agency :)
