Not at the ticket office, once you get down just beyond it. The carriages are very close to the start of the track and they will take you to the treasury, you can also go further right to the steps to the monastery.

You won't need to be an experienced horse rider because the locals will either walk the horse or ride alongside you. Be careful to very clearly negotiate a price for the ride AND for the tip before you start because some horse/camel/donkeycarriage operators can become intimidating at the end of your ride if they believe the tip should be bigger. It is important to be very clear about where you want to go before you get started so you aren't taken or led off the track to 'see another site'. Although some of the operators can be persistent, they will usually leave you alone if you are polite but firm. Also, the operators will be keen for you to buy a ride to the Monastery (the highest site at the very end of the track), but they often refuse to let you ride down from this point because it is more difficult for the animals to bring you back down again.

Hello cynthia, sorry but i do no know either whether they have one, but i am sûre the personnel there will be happy to help! Bon voyage!
