I toured Old Delhi with Pradeep of Reality Tours - who is a great guide for his knowledge, attitude and he went above and beyond in helpfulness. Old Delhi is not somewhere you'd just go to, you need to be prepare for the onslaught, and this is exactly what I was hoping to experience in India. Apart from the intense human side of things, I don't know how we managed to fit in so many living historical points. One minute I was wondering if I'd ever smell again after a stroll down chilli alley, the next I was rolling chappatis in a Sikh mosque 'soup kitchen'. This is highly interactive, interesting, excellent value, it's a no-brainer. Can't recommend Pradeep highly enough. Probably not for the soft or sensitive. It's reality.
