Yes, of course, such excursions exist. The cost of land or water will be 200-300 USD, air - 300-400 USD. I advise you to fly by air.

In general, Peter is an extraordinary place, mysterious, beautiful and frightening at the same time (the last epithet is my personal impression). There are so many legends and myths associated with it, and until now no one knows exactly what it is, this Peter actually and for what purpose it was created. Having listened to the version of the guide, just try to distract yourself and listen to yourself, I am sure that another beautiful fairy tale or fantasy will be born. In general, I highly recommend, be sure to see Petru.

I wish you a good rest!
