Bali has a waste problem, and any honest sustainability page has to say so. The island's rainy-season beaches make it undeniable, the plastic comes back with the tide, and a lot of it is ours. The good news is that a two-week trip has more leverage than people realize. Here's a practical guide, not a lecture.
Water
Single-use plastic water bottles are the single biggest waste category tourists generate here. The fix is embarrassingly simple: a good reusable bottle and a plan for refilling it. Many warungs, cafés, and homestays now offer filtered refills for free or a few thousand rupiah.
- Bring an insulated 750ml–1L bottle. Cold water in the heat matters more than you think.
- Ask 'boleh isi ulang?', 'can I refill?', at any café you eat at. The answer is almost always yes.
- Skip the little branded water bottles in hotel rooms; leave a note if you can.
Packing
- A cloth tote for markets. You will use it every day.
- A small set of bamboo or steel utensils. Warungs sometimes hand out plastic spoons by default.
- Reef-safe sunscreen (no oxybenzone, no octinoxate). This matters if you go anywhere near the water.
- Solid shampoo/soap bars. They pass carry-on rules and don't leak.
Transport
Bali is small, but you'll be tempted to zigzag across it. Every hour in a car is fuel, traffic, and time you're not spending in one place properly. Build your route so you're not backtracking. If you can, share transfers with other guests, and consider staying two or three nights in each area rather than one.
Waste, honestly
Recycling infrastructure on the island is patchy. That means the most impactful thing you can do is not generate the waste in the first place. What you do generate, batteries, medications, electronics, carry home with you. Your home city almost certainly has better disposal than a Balinese village bin.
The daily test
At the end of each day, look in your bin. If it's mostly food waste and a bit of paper, you're doing well. If it's a pile of little plastics, that's your signal for tomorrow. Two weeks of small corrections adds up to a trip that doesn't leave a mess behind.
