George Town murals are best early before heat and traffic. Hawker centres peak at lunch and after dusk - go slightly off-peak for seats.
Ferries & Rapid Buses
Ferries and bridges link the island to the mainland; Rapid Penang buses cover beaches and hills. Grab fills gaps cheaper than hotel cars.
Temple & Park Fees
Many clan houses and temples request small donations; Penang Hill and national park areas have tickets. Street art walks are free.
Heat & Food Safety
Tropical heat builds fast - hydrate and use shade. Choose busy hawker stalls with high turnover; carry hand sanitizer.
