Bottom line first: Before hitting the water, pick the right waterproof gear—waterproof waist bags for snorkeling or beach play (light and flexible, recommended: Earth Pak, HEETA); for more intense activities like rafting or ATV riding, opt for more durable dry bag solutions. Keep passports, cash, and other important documents inside waterproof gear—don’t let water damage or loss spoil your trip. Below are detailed recommendations by activity type.
Going on a Bali vacation, the most exciting part is those thrilling outdoor activities—snorkeling in the sea, tearing it up on an ATV, and rafting adventures. But honestly, worrying about your passport and wallet falling into the water while you’re having fun is a real buzzkill. I’ve made that mistake myself, nearly soaking my entire wallet, and since then I’ve learned: bring the right dry bag, and you can fully enjoy the activity.
Why Are Dry Bags So Important?
You might think, ‘It’s just a few hours of fun, what could go wrong?’ In reality, mud and water from ATV rides, accidental drops, waves while snorkeling, or even capsizing during rafting—these are all real scenarios. A soaked passport is a hassle, but worse, if your documents or cash are destroyed, the rest of your trip won’t be fun. A good dry bag can truly be a lifesaver.
Choose a Dry Bag Based on Your Activity
Different activities call for different waterproof solutions. Here are the three common types I’ve summarized for you:
1️⃣ Waterproof Waist Bag—The Most Flexible Sidekick
If you want to travel light without carrying too much, a waterproof waist bag is your top choice.
- Can hold small items like your phone, wallet, passport, etc.
- Wear it around your waist or as a crossbody—no worries about it falling off while you’re active
- Perfect for snorkeling or playing by the beach—you can easily pull out your phone to take photos
Recommended brands: Earth Pak, HEETA
Both brands make sturdy waterproof waist bags, especially HEETA—their seal design is truly impressive. I’ve used them multiple times without any issues.
2️⃣ Waterproof Phone Pouch—A Must for Photo Lovers
Love snapping photos while you play? A waterproof phone pouch is made just for you.
- Specifically designed to protect your phone, usually with touchscreen functionality so you can use it without taking it out
- More targeted than a waist bag, lightweight and space-saving
- Especially great for capturing underwater scenery while snorkeling
Recommended brands: YOSH, JOTO
Both brands offer phone pouches with excellent clarity, so your photos won’t lose any sharpness. Plus, they’re affordable—so even if one fails, it won’t break the bank.
3️⃣ Dry Bag—Your Go-To for Carrying Lots of Gear
Planning to stay all day and need to bring a change of clothes, camera, or other gear? A dry bag is your large-capacity solution.
- Fits a camera, GoPro, change of clothes, sunglasses, and more
- Roll-top seal for superior waterproofing
- Can be worn on your back or strapped across your chest without restricting movement
Recommended Brands: Ocean Pack, Sea to Summit

I’ve personally used Ocean Pack, and their dry bags are truly waterproof and durable—once you try one, you’ll see the investment is worth it. They’re especially great for multi-day adventures.
My Tips for Choosing a Waterproof Bag
To be honest, before I head out, I always ask myself three questions:
- What valuables am I carrying today? If it’s just a passport and some cash, a waterproof waist bag is enough.
- How long will I be in the water? The longer you’re in the water, the higher the waterproof rating you need.
- Do I need to access my stuff often? If you’ll be grabbing things frequently, choose a style with an easy-to-open opening.
Based on these three questions, you can decide which type of waterproof bag to buy.
Final Reminder
Waterproof bags may cost a bit more, but compared to ruining your passport or losing your credit card, they’re a much better deal. Plus, a good waterproof bag isn’t just for this trip—you can use it at other beach destinations or even on international travels.
Another option: if you have a trusted ATV driver or guide, you can leave your passport and most of your cash with them. Highly-rated, reliable drivers in the community (check out this guide) are usually happy to help, so you can fully enjoy the activity without worrying about your belongings. This method works especially well for group activities or when you have a driver you know well.
Most importantly: Use the right tools or find the right people, so you can safely enjoy every moment of adventure. Next time you’re in Bali, don’t forget to bring a waterproof bag, or ask your driver in advance if they can keep your belongings safe, so you can have even more fun.
