Watching the wild dolphins turn up for a feed each morning in the shallow waters of Monkey Mia, 26km northeast of Denham, is a highlight of every traveller's trip to the region. Watch the way they herd fish upside down, trying to trap them against the surface. The pier makes a good vantage point. The first feed is around 7.45am, but you'll see them arrive earlier. Stay around after the session, as the dolphins commonly come a second ot third time.
Note that visitors are restricted to the edge of the water, and only a lucky three people per session are selected to wade in and help feed the dolphins.
Monkey Mia Visitors Centre has information and tours.
You can volunteer to work full time with the dolphins for between four and 14 days – it's popular, so apply several months in advance and specify availability dates, though sometimes there are last-minute openings. Contact the volunteer coordinator .
