Overview
Kuala Lumpur's museums cluster in two walkable areas. The Perdana Botanical Garden (Lake Gardens) district holds the National Museum and the Islamic Arts Museum Malaysia. Around Merdeka Square, in the colonial core, the National Textile Museum fills a striped Moorish-style landmark. Government museums charge foreign adults RM5 (Malaysians RM2), the National Art Gallery is free, and Petrosains at KLCC is the city's big hands-on science centre.

Best time to visit
Kuala Lumpur is hot and humid all year. Heavy afternoon thunderstorms are most frequent in the wetter spells around March–April and October–November, which makes indoor museums good midday refuges. Go on weekday mornings to avoid school groups. The national museums close for one or two days at Hari Raya Aidilfitri and Aidiladha.
