Hello! It's great to hear that you're planning your trip to Riyadh, Ta’if, and Mecca. Here are some travel tips for your journey.

Best Time to Visit:
The best time to visit Saudi Arabia is during the cooler months from November to March. These months allow easier exploration of the cities without the intense heat. For Mecca, do note that the Hajj period is the busiest time of the year, so if you want lesser crowds, plan your visit accordingly.

Route and Accessibility:
You can reach Riyadh via air, as it is serviced by King Khalid International Airport. From Riyadh, Ta’if and Mecca are accessible by road. Ta’if is approximately 780km from Riyadh via Route 40, and Mecca is another 90km from Ta’if.

Accommodation and Booking:
Both Riyadh and Mecca offer a wide range of accommodations from luxury hotels to budget options. Ta’if also has numerous hotels, but with less variety. It's best to book your accommodation in advance, especially in Mecca during the Hajj and Umrah seasons. Websites like Booking.com or Airbnb provide good options.

Clothing and Essentials:
Given the conservative nature of Saudi Arabia, both men and women are expected to dress modestly. For women, an Abaya is essential. Even in the heat, clothing should cover shoulders and knees. Don’t forget your sunscreen, sunglasses, and a hat. For pilgrimage in Mecca, specific clothing is required.

Health and Safety:
Drink plenty of water to avoid dehydration. Follow the local traffic rules vigilantly. Women, in particular, should be aware of the local customs regarding interaction with men. For safety, always keep a track of the local emergency numbers.

Local Etiquette and Respect:
Saudi Arabia is a conservative society rooted in Islamic traditions. Respect the local customs, particularly during the holy month of Ramadan. There are also specific religious customs to be observed in Mecca during your pilgrimage, which you should learn in advance.
