Choose a beach bag that is big enough to fit a beach towel and all the essentials like a water bottle, change of clothes, sunscreen, book and snacks. Water resistant or mesh bags are the best type of bag to bring to the beach because they’re easy to clean and keep sand out of. Adding a sling bag or small crossbody bag to your beach bag also means you have a great spot to put your valuables in and makes them easily accessible for when you need to run to the beachside café across the road.
