Mason Bay is a very isolated west-facing beach located on Stewart Island. It’s about a 1-hour boat ride from the mainland, which makes it a bit of a trek. While there are definitely more bird watchers than surfers on the island, it still offers a unique spot for those looking to catch some waves away from the crowds.

The surf here can handle swell sizes at about 2 feet (0.6 meters) and breaks mostly over sand. The best waves come in from the south and southwest, making those directions ideal for a session. You can expect beach breaks with both left and right waves. For the best experience, aim to surf during low, mid, or high tide, and an east wind tends to work well. This spot is generally suitable for beginners, so it’s a great place to practice your skills or enjoy a laid-back surf.

Since Mason Bay is quite remote, don’t expect tons of surfers around. It's a perfect getaway if you're looking for some peaceful surfing or if you want to escape the hustle of busier spots. Just keep in mind that being in such a secluded area means resources can be limited, so plan ahead if you're making the trip.
