Alonissos.com

A half completed site, but still worth visiting. Good info on the nearby Marine Park and its Monk seals. The photo page is also okay. Best thing about the site is the ferry timetable - though it isn't always kept fully up-to-date.

GreekIsland.co.uk

A clickable map takes you to pages with photos and text about the island.

Laskarina

Page with photos from one of the island's leading upmarket package tour operators. Information is inevitably pretty basic.

Vacation.net

Half a page of text and one photo that could be of anywhere.
