Thanks for the question! My favorite ground type has to be Diglett. Just a little guy. Very shape.
As for the highest I’ve been on solid ground, I’ve gone pretty high up Mount Rainier. The views from up there are beautiful.
Bonus: I’ve been in one of those tour boats where you can go below the water and look outside windows at the fish. That’s probably the lowest elevation I’ve been at, just not on solid ground.
