ORP Groźny is one of the most visited wrecks. It rests evenly on the keel, there is no net or other external dangers on it, so it is ideal for beginner divers. It is worth paying attention to the rails in the stern part, after which deep mines were dropped, many manholes into the rooms inside the wreck and a large superstructure. Inside, there are many interesting places, although entering in, due to the quickly deteriorating visibility caused by sediments, requires the right technique and configuration as well as proper training.
