I visited the Burans in 2020. Decided to go in winter; figured the risk profile would be lower (security, extreme weather). It's definitely an effort to get to. Sadly one of the Burans was tagged after our visit. The hangar is just next to Gagarin's launchpad, which was fairly amazing to witness.
Photos for the curious.
