The public boat ramp at Lyttelton sits within Whakaraupo / Lyttelton Harbour and is described as sheltered and well-equipped, making it a popular departure point for boaties exploring the harbour. It can be a busy spot during summer weekends and holidays.

Kamautaurua Reef lies just off the slipway area and is well marked; once clear of the slip, marina, and reef, the broader harbour opens up.

Boaties should be aware of the tidal nature of the upper harbour — low tide renders many areas unusable, and tides can recede quickly. Consulting a maritime chart for depth information is recommended before heading out.
