Riyadh is the capital of Saudi Arabia, a sprawling modern metropolis at the heart of the Najd plateau, and a rental car is a practical way to move between the city's business districts, historic sites and outlying desert areas once you are past the airport arrivals hall. Most visitors land at King Khalid International Airport (RUH), a large facility north of the city with rental counters from international and local operators inside the terminal, and pickup is generally straightforward given the airport's well-organized ground transport area.
From RUH, downtown Riyadh and its landmark towers are roughly a thirty-to-forty-five-minute drive south on wide, modern expressways, while the historic Diriyah district, birthplace of the Saudi state and a UNESCO World Heritage site, sits a little northwest of the city center, reachable in around forty-five minutes from the airport. Heading further out, the Edge of the World escarpment, a popular desert excursion, is roughly ninety minutes to two hours northwest of the city along a mix of highway and unpaved approach roads.
Driving is on the right throughout Saudi Arabia, and Riyadh's road network is extensive and modern, with multi-lane expressways, ring roads and well-signed junctions connecting every part of the metro area; traffic can be heavy during rush hours and around prayer times, when many businesses pause briefly. Riyadh's defining seasonal factor is heat: summer temperatures routinely climb past forty degrees Celsius, so air conditioning, hydration and avoiding midday desert excursions matter more here than road conditions themselves, which are generally excellent on the main routes. Fuel stations are plentiful throughout the city and along the highways leading out to the desert, and fuel prices are notably low by international standards. A standard sedan handles city and highway driving comfortably, though a vehicle with a bit more clearance suits unpaved desert approach roads like the one leading to the Edge of the World better.
