Batu Caves vs National Mosque of Malaysia (Masjid Negara)
Two temples in Kuala Lumpur. Batu Caves has 4 tickets and tours to book; National Mosque of Malaysia (Masjid Negara) has no online ticket listed. The table and the two notes below put them side by side; the full pages have what to see, the ticket and the timing for each.
The main sight at Batu Caves, the Temple Cave at the top of the great staircase, is free to enter, so you do not need a ticket. A few side attractions at the foot of the hill, such as the Ramayana Cave and the Cave Villa, charge a small fee paid at their own doors.
That means the tours sold online are about transport, company and context. The most popular are half-day trips from Kuala Lumpur by car or minivan with a guide, often combined with other places of worship in the city: the Chinese Thean Hou Temple, the National Mosque and the Sri Mahamariamman temple in Chinatown.
There is nothing to book for the National Mosque, and no ticket for it alone is sold online. Non-Muslim visitors are welcome free of charge during set visiting hours outside the prayer times, entering through a dedicated visitors' entrance where robes and headscarves are handed out at no cost and shoes are left on racks. Volunteer guides are often on hand to explain the building and answer questions about Islam, again without charge.
Many travellers see the mosque on a half-day or full-day Kuala Lumpur city tour.
