Rakaia Huts Campground
This is a river mouth environment nestled in a sheltered reserve near the Rakaia River and the sea. Sea fishing opportunities. Short term camping only. Well maintained reserve and playground, which includes a basketball hoop. Surfing opportunities near the mouth. If the conditions are right, then you can catch some short tubes created by the river exiting out to the sea.
This site is free, but would love a nightly $5 donation.
