The city of Amer is just next to Jaipur and is older than the Pink City. Here, you can plan a half or a full day tour, and our suggestions to explore Amer is like this:
Later you can explore the markets of Amer which is famous for its statues, blue pottery, etc. But be aggressive in bargaining 🙂
If you have two days in Jaipur, then we suggest a whole day for Pink City part of Jaipur, and the second day for Amer. Else, you can also visit sites like Jal Mahal, Amber Fort from 3 pm to 7 pm, which we normally suggest to our guests who only have a day for Jaipur Sightseeing tour.
