We had a brilliant day at the Wolf’s Lair and Mamerki, with Piotr as our guide. He was very nice and accommodating, and also fairly knowledgeable. As I have very specific dietary requirements, he ensured I got a meal that suited my needs at lunchtime. He had the added challenge of the bunkers at Mamerki being closed, so was left to bring us around the smaller bunkers, while explaining how the larger bunkers were laid out. He was very knowledgeable of the history of the Wolf’s Lair, and the particulars of the place in terms of measures taken to conceal the area from the air, it was really very interesting. Our trip did not include Swieta Lipka.
