If you find Corsair bay to be too busy with the large amounts of teenagers and their friends, then Cass bay is a great option for the more relaxed approach.
Cass Bay is three and a half kilometres from Lyttelton town centre, and 15 kilometres from the Christchurch city centre. It is made up of three different beaches and there is a track that weaves through the bushes to take you to each one. Personally, my favourite beach is the furthest one away from Cass Bay's biggest beach. It's a lot quieter and if you're lucky enough to be there when no one else is, it's so quiet you could hear a pin drop. It's a cove-like beach, so it can feel like your own little remote getaway spot.
The main and biggest beach at Cass Bay has a playground for the kids to explore while you soak up the sun (in summer of course). Now, although it is winter, Cass Bay still has a lot to offer with a boat ramp so you can take the kids out on the kayak or paddle boat. There is also a walking track that is available which starts at Cass bay, takes you past Corsair, ending at Pony Point on the hill. In summer Cass Bay has a pontoon floating in the water, allowing the kids (or adults) to jump off or just relax floating on the water.
On the other side of the Lyttelton tunnel there is a lot to offer, making it feel like a completely different country. Cass Bay is a real hidden gem and definitely something you should try, whether that be in winter or in summer.
