Anyone know where the biggest Secret Base is?

[Pokedex]

Hi, I was wondering if anyone knew where the largest secret base is. I haven't gone to every single one, but I'm getting tired of searching.

Thanks In Advance,

Route 126. You need surf/dive to get there but i believe that he biggest base is there

just remember there's a limit to the decorations so biggest is not always best

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
