The red minibuses don't have fixed stops and routes change based on traffic, but they're often faster than the MTR for certain routes. You flag them down and tell the driver your destination. Payment is exact change only, usually HK$5-15.

Watch locals for the hand signals — Different gestures mean different destinations. Useful for getting around areas not well-served by MTR, but definitely not beginner-friendly transport. Green minibuses have fixed routes if you want something more predictable.
