You can reach Abhaneri from Jaipur in 3 ways:
1 - Take a bus to Sikandra, which costs around 20 rupees. From there take a jeep or taxi to Abhaneri, which costs about 300 rupees for a round trip.
2 - Take a bus to Gular and walk to Abhaneri (which is about an hour's walk.)
3. Drive or take a taxi from Jaipur which will cost about 3000 rupees if you can split it with someone. Or simply drive, if you have a car.
As of now, there is no entrance fees for viewing the monument.
