Genshin Impact: All Echoing Conch locations for Barbara’s swimsuit (Act II)

Twinning Isle: Moon and Wind, Clan of Song, and Wisdom of the Ancients

The main island (Twinning Isle) has three Echoing Conches.

“Moon and Wind” requires you to glide directly southwest of the fast travel point. You’ll find a small nook with the Echoing Conch and a journal.

The journal actually gives you a clue on how to reach a secret island (more on this later).

Head west from this area and you’ll find “Clan of Song, Scattered” on the cliffside.

Next, tag the nearby Waverider spawn point and follow the coastline going north.

It should lead you to a giant fossil with the “Wisdom of the Ancients” Echoing Conch inside it.
