Open all day but miss prayer times if not praying

Hi Hello Elodie T, Don't worry, there are private storage / lockers available, and there is a guard, sure to be very safe. Best Regards & Friendship, Java Private Tour.

Sarong (man) and kaffetani (women) are available at the info point at the entrance. The mosque is viewable only with a guide, English speaking for a donation. Obviously not shoes . I think under the knees trouser is accettable.

Beberapa hari menjelang lebaran disediakan makan sahur, tp harus siapa cepat dia dapat

No you don't need to come in a group you are always welcome during office hours but you must take of your shoes and someone will guide you around of the official employees and if you where a short they will give you something you can use to see the mosque.

Sangat dibolehkan walaupun hanya sekedar lihat2

If you take a tour, which you will most likely have to do, there is a small area to keep your shoes (which you need to take off at the very entrance to the mosque). If you are dressed inappropriately, they will give you a robe to cover up that you return when the tour is finished.

I can answer my question now :) it takes 40-60 min from airport to mosque by taxi. Taxi drivers want 190-250 rupiah. We made a deal with a taxi driver from airport to city center tour that takes 5 hours. Driver had taken us from airport, take to the city center, we went to mosque, cathedral, and symbol of the city -can't remember name, may be national monument- We paid 600 rupiah

Dear Dawid Z, to witness and experience during late hours and nights are exceptional unique due to the lights and architecture will emerges its grandeur, as the Istiqlal were design in a complete thinking and lots of precautions thinking behind the plan when its build. best time is after the last pray calling, Isya is at 19:00 that time will filled with many people doing the pray, if you wanna witness that then come after or within time. but if you wanna see the mosque tranquil and serene within the lights, is best after 20:30 .... visitor are welcome but not to most area. one of the magnifying is the main hall of the pray area, where the dome are desgin as if.. you are in earth sitting and bowing to the mighty, and when you look above you, the chandelier is design Moon alike and above that, the dome lights are design as if gleaming like the sun... amazing ....
