Cass Bay Beach is a harbour-side beach in the Christchurch City area of Canterbury, rated 4.6 from 329 Google reviews. It is described as a tranquil cove between Lyttelton and Governors Bay, with calm water, pebbly shore and sunset views over the hills, a short drive from the city.
A beach with a pavilion or simple facilities is at its best when you plan around the tide, the weather and the time of day. Harbour coves tend to be sheltered, which suits families with young children, but water is often shallower at low tide and cooler than you expect, so check conditions before swimming. Bring shade, water, sun protection and shoes for pebbly shores, and take your rubbish home. Early morning and late afternoon are quieter, and sunset is a popular time to visit, so arrive a little early to find parking. Check any signs about water quality and swimming advice before heading in.
For Christchurch families and visitors exploring Lyttelton Harbour, it is a calm, scenic place for a swim or a picnic by the water.
