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.
