If you follow a small path from the plane wreck towards the coast, you will reach the beach. It's maybe an extra 5-10 minutes. In general, you should be careful there. Even in summer it can be very stormy and push you closer to the water if you're standing in an unfortunate position. The waves are also very dangerous then. It's better to look at it from a respectful distance. On the way back to the wreck, be sure to follow the path again. It's very easy to get lost there.
