What is this place?

[Genesis]

So I got the crystal key and remembered that in tanzan mountain west there was area that had a crystal rock and I went there and followed the pathway and got to this area:

I have no clue what it is or where it goes. Can anybody let me know? I don't mind figuring out how to get past it, just want to know whether its worth the effort?

Also I have been seeing a bunch of areas that have rock climb walls but have not yet found rock climb. I also havent found surf or fly which is a pain when having to go across the map to cities for quests. Should I have gotten them yet or do they come later in the game? I have currently just set Luna free from the arceus cults on 7th street

You also get the Yuyeru Key which lets you acess the locked doors in Shade's gym. In there you get a TM, Rotom, and the ability to evolve Magneton into Magnezone and Nosepass into Probopass.

Thanks TimTim and DragonI will definitely work on that then

I am at work at the moment and my server blocks youtube, could I ask please if you could give me the link to the youtube video instead that way I can access it indirectly. At the moment I can't even see the name of the video or a pic of it
