Ukrainians made a video about Crimea.

Sevastopol is beautiful, Poroshenko amd Zelensky lost Crimea and Sevastopol, so they r saying shit to them
Cant get it, destroy it. Thats what ukraine doing now

Regarding the destruction of "Ukrainian energy" - remember how the Ukrainian Nazis blew up power poles, leaving Crimea without electricity? Then Putin ordered the laying of electrical cables along the bottom of the Kerch Strait, and before this was done, Russian ships entered the Crimean ports and supplied electricity from the ship's generators.

The parks were still there - they were put in order and cleared. I can recommend visiting the Nikitsky Botanical Garden (it is located in Yalta) and the Crimean Park with lions "Taigan" (Belogorsk).
Beaches have become free. You pay money only for services - a sun lounger, drinks, and so on, but the stay on the beach itself is now free.
"No Ukrainians" - is a lie. Ukrainians and the Ukrainian language are everywhere, and many rural residents speak it. It is ok. Many signs and announcements in shops or museums are duplicated in Ukrainian and Tatar. Hotel "Ukraine" in Sevastopol as it was, and remains with this name. I also often met cars with Ukrainian license plates in the Crimea - I don't know if they were visitors or someone else didn't have time to change the license plate to a Russian one. No one points a finger at them, breaks windows, or sets them on fire.
