Runner-Up, Best Overall: SAFEGO Portable Lock Box
The Safego Portable Lock Box earns top marks for its quality, convenience, affordability, and durability. It’s a lightweight safe that’s small and portable, but strong enough to keep all your valuables safe. There’s plenty of room to stash your wallet, cash, keys, phone, camera, and sunglasses when you want to head into the water or go for a walk on the beach. Safego is simple to use and can be opened using either a key or a three-digit custom combination, which can be changed as often as you'd like.

Even if you’re lounging right next to your stuff, you may choose to keep your valuables in your Safego to protect them from the elements. It comes with an adjustable plug opening, so you can listen to music while your device is safely inside the box. Safego also comes with a heavy-duty, 17-inch adjustable cable that can be used to securely lock around almost any fixed object. You can also use the cable as a handle to tote your lock box to the beach or pool. The Safego comes in different colors, including white, pink, black, gold, and blue, so you can choose one that best suits your style.
Best Large Bag: LocTote Flak Sack Sport
If you need a beach bag that can hold more than a handful of electronics, the Loctote Flak Sack Sport backpack has the extra space you require. This stylish drawstring backpack measures 13.5 x 18 inches and is made of double-layered, slash-resistant fabric. An internal pocket is ideal for credit cards and comes equipped with RFID-blocking material. The exterior is pretreated with industrial-grade stain and water repellent. There’s a main locking strap that is reinforced with stainless steel that is cut-proof and comes with a combination lock. For comfort, sternum straps can help reduce pressure so you can carry it around town after spending time on the sand.
Best for Travel: Pacsafe Travelsafe Portable Safe
The PacSafe TravelSafe is light and folds flat for easy packing, making it a perfect safe for beach vacations. Like other portable safes, you can store your valuables inside and secure it to a stationary item. It features a TSA-accepted three-dial combination lock, a padded EVA foam laminated and soft brushed polyester lining, water-resistant exterior, and handles for convenient carrying.
In addition, the poly-canvas material is embedded with Pacsafe's patented 360-degree eXomesh locking system and a stainless steel wire mesh, so you can feel confident that your valuables are safe inside. It’s available in two sizes: the 12L model can fit a 13-inch laptop, while the 5L model is big enough to store an iPad (10-inch tablet).
Best Tote Bag: CoolBag Gen 2 Locking Anti-Theft Travel Tote
If you’re heading to the beach, you’re most likely bringing along a cooler and a beach bag, so why not carry one that can also keep your valuables safe? The CoolBag Gen 2 is a versatile, high-quality and durable bag with anti-theft features including a puncture-proof zipper, slash-resistant fabric, and a combination lock.
The padded cable straps/handles can be detached and used to wrap the bag around a stationary object, securing the CoolBag and its contents. Other security features include inside RFID pockets to protect passports and credit cards. It’s easy to stay organized with the CoolBag’s inside mesh pockets, side water bottle pockets, magazine pocket, and padded section for tablets.
The cooler compartment allows you to access cold snacks and drinks from inside or outside the bag. Although this bag is on the expensive side, it’s worth the price for the top-notch features, security, and high-quality.
Best for Portability: FlexSafe by AquaVault
From the company that also makes the AquaVault, the FlexSafe is more portable than some other beach safes. Although it won’t hold as much as the AquaVault, it’s light and very versatile. It can be secured to any fixed object, such as your lounge chair, stroller, bike, or beach umbrella, and also features a belt loop and padded carry strap, so it’s easy to take on the go. The portable safe is water-resistant, slash-resistant, made of heavy-duty materials, and also features RFID blocking to protect data on your electronic devices.
Most Discreet: Stash-it Diversion Water Bottle Can Safe
This Stash-it Diversion Tumbler may look unassuming, but it's actually a water bottle with a secret safe. Just unscrew the bottom of the bottle and store your keys, cash, jewelry, and other small items in the 2.5 x 2.5-inch compartment. The water bottle itself can hold 16 ounces of liquids, with a leak-proof lid and stainless steel construction. Thanks to its portability, you can also use the bottle wherever your travels take you, whether you're going camping or to the gym. Stay hydrated at the beach while storing your valuables away with this innovative safe — no one will ever know your diamond ring is hidden in your water bottle.
Best for Phones: Mpow Universal Waterproof Case
Your phone is almost a necessity when having fun at the beach, whether you're snapping photos of your family or shooting videos of the surf — though keeping it dry is a challenge. To keep your phones away from the water (and theft), consider the top-selling Mpow Universal Waterproof Case. Suitable for smartphones up to 6.5 inches, including iPhones, Galaxys, and Google Pixels, the case also acts as a portable safe for your cash, keys, cards, and more. It even features a fully-sealed lock to prevent water or sand from seeping in. For peace of mind, the waterproof phone bag is IPX8-certified, meaning it's fully submersible (though a safety test is recommended before using it). All this and the transparent cover still makes the phone's touchscreen easy to navigate with.
What to Look for in a Beach Lock Box
Size 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.
Style Some lock boxes come in literal box or case form. Others are actually bags—think small backpacks and totes that can hold electronics, repel water, and keep valuables safely protected with a lock.
Opening 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.
