No special access issues
All sectors are located in municipal areas and there are no particular problems with access. It will not take more than a few minutes to walk from the proper parking lot to any sector.
The most popular fort Waldersee (Lechicka / Umultowska) has a guardian. The parking space is subject to change.
The forts are known as the habitat of bats. Do not to wake them up and scare them away. Especially in winter when they hibernate.
Unfortunately, the area of the forts is sometimes littered. Try not to make this situation worse.
