Best pop-up camp location?

[Null Winter]

Forest 8. Behind the waterfall. Never gets discovered. 3 mining spots next to the tent with another 2 right outside. 2 fishing spots absolutely loaded up with all the money fish. 2 possible Wyvern Coin spawns. 3 coral spawns so you can trade them for more Coins. Lizards on the wall and fish in the water if you, for whatever insane reason, need more research points. It's somewhat central in the region and is a 20 second sprint from the major swimming farm spot.
It feels like a "dev spot"; a "secret" location to ease grinding during development when you don't have a full dev toolkit available to just add or remove something.

Do any of the locations in any region even come close to being this valuable and convenient?
