The boat ramp at Humphreys Drive and Tidal View sits on the Ōpāwaho/Heathcote River near where it opens into the Avon-Heathcote Estuary on the eastern edge of Christchurch.

The river's deep tidal channels have made this stretch an important waterway for centuries, historically used by Māori canoes travelling between the pā of Ōpāwaho, the estuary, and Rāpaki. The surrounding area is a noted wind-sports hub.

When high tide coincides with a stiff easterly, windsurfers and kitesurfers gather at the Humphreys Drive foreshore to take advantage of the conditions, making this a lively stretch of water for a range of paddle and sail activities.
