Best Beach Lock Boxes

TripSavvy / Chloe Jeong

There’s nothing that can kill a beach day buzz quite like realizing your wallet or smartphone has been plucked from your beach bag while you were dipping your toes in the ocean. Beach theft is, unfortunately, quite a common occurrence. But you don’t have to shove your smartphone into your bathing suit or swim trunks just to ensure it doesn’t get stolen while you’re away from your towel. That’s where beach lockboxes come in.

Anti-theft lock boxes and bags are designed with your security in mind: They come in various shapes and sizes depending on what you’re hoping to keep safe, ranging from smartphone-sized safes to full-sized laptop bags and even discrete water bottles designed to conceal jewelry and cash. Another thing to consider is the type of locking device. Do you mind carrying a key or is a combination lock better? Lastly, a durable lockbox made to resist water, sand and salt will last you much longer.

Below, we've rounded up some of the best beach lockboxes for all types of travelers and beach bums—you’ll want to consider picking up one of these before your next beach vacation.

What to Look For in a Beach Lock Box


Think about what you want to put in the box—just the most valuable items, or would you rather have enough space for everything you’re taking with you that day? Lock boxes come in a range of sizes so think about what’s best for your lifestyle and choose accordingly. The size will also affect how easy the lock box is to transport.

Locking Device

There’s a variety of ways to unlock secured valuables, and it can be an important consideration in the purchase of a beach lock box. If you don't want to travel with keys, then opt for one that opens with a combination code. Keep in mind, though, that lock boxes with three-digit combinations might compromise security. It's also best if the location of the locking device is discreet so that the box doesn't attract the unwanted attention of other beachgoers. Consider the environment in which you will be bringing the box when weighing what type of locking device is necessary.


Durability is one of the most important factors to consider when shopping for the right beach lockbox since you’ll be schlepping it into the sand and briny water, after all. Beach lock boxes designed to be resistant to water, salt and sand will help protect your valuables and will ensure the box itself remains in great shape for years to come. You should also look for beach lock boxes with a warranty or lifetime guarantee for added peace of mind.
