Bring a bottle of water and your camera, but leave any other valuables at home — the Old City is crowded and there are pickpockets lurking about.
As you clamber to the surface, you'll find yourself in the middle of a bustling bazaar — this is Chawri Bazaar. Hail a cycle rickshaw and ask him to take you to ''Jama Masjid,'' which shouldn't cost more than 20 rupees. It's not far in terms of distance, but it'll take a while, as the bazaar here is always packed to the hilt, but this just gives you a good chance to look around. Many shops on Chawri Bazaar and adjoining Nai Sarak are devoted to stationery, and in particular the colorful, handmade and exquisite '''invitations''' that are a prerequisite for any Indian wedding.
Soon you'll see the great dome of '''Jama Masjid''', India's largest mosque, looming ahead. The cycle rickshaw will drop you off at one of the gates, so take off your shoes and head in. Entry is free, but a photo permit is Rs.200 and the gatekeeper will want a little baksheesh if he keeps your shoes for you. Don't miss the climb to the minaret (an extra Rs.20) for great views of the city.
Head out from the mosque's north gate and follow the curving road, then turn left. Many shops here specialize in fireworks, another Indian wedding staple, but right up the road is '''Cycle Market,''' which deals not just in bicycles, but in cameras.
You've now reached Chandni Chowk, the central street of the area. It was built by Shah Jahan, the builder of the Taj Mahal, as a tree-lined, half-moon shaped promenade (hence the name, "Moon Market"), but little but the name remains. To the east is '''Sri Digambar Jain Lal Mandir,''' a major Jain temple, and behind it is the Lahore Gate entrance to the Red Fort (''Lal Qila''), but that's worth half a day in itself and best left for another day.
