The Bonneville Speedway has hosted land speed record attempts since 1914. Racing events primarily happen between July and October when the 30,000-acre salt crust is dry and hard. If you visit during these months, you need to know how event schedules affect your access.
When is Bonneville Salt Flats Speed Week?
Racing events, including Speed Week, typically take place between July and October.
Late summer and early fall offer the dry salt conditions required for land speed racing. The Bureau of Land Management (BLM) permits these events during this window. Always check the official BLM schedule for exact dates before driving out, as track conditions dictate event timing.
Can anyone watch the races?
Yes, but you must stay within designated spectator zones.
During permitted events like Speed Week, general access to the open salt is restricted. The BLM manages the area to ensure driver and visitor safety. You cannot drive onto the active racing tracks or interfere with the competition areas.
Where is the Bonneville Speedway located?
The racing tracks are accessed via the Bonneville Speedway road at Interstate 80, Exit 4.
This paved access road leads directly to the edge of the salt crust. During late summer and fall, crews lay out specific track areas for speed events. Outside of scheduled events, this area remains a vast open expanse of white salt. Read more about Speedway & Access.
What are the rules during racing events?
Visitors must obey closures, pack out all trash, and avoid camping on the flats.
- Stay in designated spectator zones.
- Pack out all trash; there are no garbage services on the flats.
- Overnight camping on the salt crust is strictly prohibited.
- No drones or commercial filming without a BLM permit.
Is it hot during Speed Week?
Yes, summer temperatures frequently exceed 100°F (38°C).
The white salt reflects the sun, intensifying the heat and glare. Bring at least 1 gallon of bottled drinking water per person. Wear polarized sunglasses, a wide-brimmed sun hat, and high SPF sunscreen to protect against the extreme exposure.
How do racing conditions affect vehicles?
Salt residue is highly corrosive, requiring thorough washing after driving.
Vehicles driven on the flats pick up thick layers of salt. You must wash the undercarriage thoroughly to prevent rust and damage. Visitors leaving the Westbound Rest Area can use the outdoor foot-washing station to rinse their shoes.
Questions travellers ask
Can I drive on the salt during Speed Week?
Only in designated areas. The main racing tracks are closed to public vehicles during permitted events to ensure safety.
Are there entry fees for the salt flats?
General public access is free. However, special recreation permits, large groups, or commercial filming require fees paid to the BLM.
How far is the speedway from Salt Lake City?
The Bonneville Salt Flats are located 120 miles west of Salt Lake City. The drive takes 1.5 to 2 hours via Interstate 80.
