Although this site covers six different forts, we were a bit short on time and opted for the easiest one to visit the Amber Fort just outside of Jaipur. It's pretty easy to access, though I'd recommend using a ride-hailing service like Uber or Ola instead of organising a car through your hotel.

The Amber Fort is really more of a palace than a fort, though it certainly serves that purpose as well. There are multiple terraces and courtyards inside, each leading to an earlier and more exclusive part of the fort. There's fantastic details here at every turn, with impressive sizes matched against exquisite Mughal detailing. 

Sadly, elephant rides are still available here as an option instead of climbing up several ramps and staircases to enter the fort. It's not a long or arduous climb, though the heat and hawkers can make for a less-than-pleasant experience. 

As with every other site run by the Archaeological Survey of India (which covers most World Heritage sites), you can buy tickets directly online from the dubiously-named but actually legitimate https://asi.payumoney.com. You can then show tickets on your phone to the gate inspectors.

All up, we really enjoyed our visit to the Amer Fort. It's a large enough site that aside from a couple of areas it never really feels all that crowded, and there's a whole lot of fascinating stuff to see. Well worth a half-day of exploring at the very least.
