Sure! Here are some travel tips you might find useful for your visit to Ajmer, Jaipur, and Jaisalmer:

Best Time to Visit:
The best time to visit these places is from October to March. Winters are pleasant, and the weather is perfect for sightseeing. Summers are scorching, so better to avoid between April and June.

Route and Accessibility:
If you're starting from Delhi or any other major cities, you can take a flight to Jaipur, which is the nearest airport for all three cities. From Jaipur, you can hire a taxi or bus to Ajmer (130 km) and Jaisalmer (558 km).

Altitude and Acclimatization:
These places are not located at high altitudes, so acclimatization is not an issue here.

Accommodation and Booking:
All three cities- Ajmer, Jaipur, and Jaisalmer have a good range of accommodations from budget hotels to luxury palaces turned hotels. Make sure to book in advance for hassle-free travel.

Clothing and Essentials:
Despite the time of your visit, carry light cotton clothes because Rajasthan is known for its hot and dry climate. Also, pack a hat, sunglasses, and sunscreen to protect yourself from the harsh sun. In winter, do carry some light woolens as the desert can get quite cold at night.

Health and Safety:
Stay hydrated, especially if you're travelling during the hotter months. Avoid street food if you have a sensitive stomach.

Local Etiquette and Respect:
Remember to behave respectfully towards the local traditions and customs. The people of Rajasthan are incredibly proud of their heritage, and they appreciate it when visitors show respect for their culture. When visiting temples or other religious sites, dress modestly.

Additional tips:
While you are in Jaipur, don't miss the City Palace, Hawa Mahal, Jantar Mantar and Amber Fort. In Jaisalmer, the Jaisalmer Fort, Patwon ki Haveli, and the Sam Sand Dunes are must-visit sites. In Ajmer, the Ajmer Sharif Dargah and the Ana Sagar Lake are notable attractions.
