best volcano to see in Vanuatu?

most active and accessible? Im going in July and only have a weekend free to see one volcano.

It would probably have to be Mt Yasur with just a weekend. I would imagine it is the most active too.

Yep, see Yasur. Easy to get to and usually spectacular.

Definately Yasur. If you can, spend some time on Tanna. The White Grass Resort is magic. Snorkelling at the front door.
