Anyone know where the biggest Secret Base is?

Here, use this and find one yourself, I have mine in Rusturf Tunnel and when I get Sapphire, im going to make that one similar to that but on Secret Shore. To me those are the best looking and easiest ones to get to. :D

Edit: oh and the reason why I like them besides the easy access, you can use stairs :D
