A tie between Western Skyrim and Northern Elswyer.
It's so hard to choose. I'd probably have to say High Isle. However there are so many amazing zones in ESO. I'd say some very close contenders for me are, the West Weild, and the two Elsewheres.
Senchal is my favorite city in all of Elder Scrolls, so I am pretty attached to Southern Elseweyr, but I also love Western Skyrim, the Telvanni Peninsula, and High Isle! Oh, and Murkmire... so cool!
Thank you for all of the responses so far! I just got home I'll try and reply to them all tonight! But it's very nice to know I'm not the only person who has trouble picking a favorite 😂
Rivenspire and Western Skyrim.
Elsweyr, Summerset, Coldharbour. Interesting places with scenic views, architecture and fauna
Auridon has been my favorite place to knock out daily endeavors lately, but it's hard to pick an overall favorite zone.
Auridon and Summerset. I just think they are both serene and beautiful. Though Summerset is a little rundown, as though the Altmer are in decline. Then it’s Wrothgar. A very different, rugged beauty. ☺️
Southern Elsweyr is absolutely gorgeous.
Vvardenfell for sure, but I'm happy anywhere in Morrowind.
