As with any popular tourist destination, Indonesia has its share of scams. Here are some common ones to watch out for:

1. Money changers: Some money changers may use tampered scales or fake notes, so use reputable banks or currency exchange offices instead.

2. Taxi scams: Use licensed taxis or ride-hailing apps, and always check the meter is on.

3. Gem scams: Be cautious of overly friendly locals offering "deals" on gemstones or jewelry.

4. Street games: Avoid participating in street games like "find the ball under the cup," as they're often rigged.

5. Overpriced goods: Be wary of inflated prices for souvenirs or goods, especially in tourist areas.

6. Fake tours: Research tour operators thoroughly to avoid booking with unlicensed or fake companies.

7. ATM scams: Be cautious of tampered ATMs or suspicious individuals nearby.

8. Drink spiking: Never leave your drink unattended, and be aware of your surroundings in crowded bars or clubs.
