I uploaded pictures of this part on https://commons.wikimedia.org/wiki/File:Electric_fence_along_a_walking_path_in_Wolfenschiessen_(Nidwalden,_Switzerland)_(IMG_20210821_184303).jpg and https://commons.wikimedia.org/wiki/File:Electric_fence_along_a_walking_path_in_Wolfenschiessen_(Nidwalden,_Switzerland)_(IMG_20210821_184323).jpg . These posts could actually be picked up and stuck back in the ground, I don't know if this is standard practice. Unfortunately I don't have pictures of the previous one with a turnstile surrounded by electrical fence where it was impossible to go through safely without crawling and/or taking off our backpacks.
