Frequently Asked Questions

Where can I park to access the Old Highway 91 Hill Climb?

Is this route dog-friendly?

This route is primarily a road cycling experience on an old highway. While dogs are generally allowed in vehicles on public roads, it's not typically considered a 'dog-friendly trail' in the traditional sense for walking or off-leash activities. Always ensure your pet's safety and adhere to local regulations if bringing them along in a support vehicle.

What is the best time of year to cycle this route?

Given its desert landscape, the best times to cycle are generally spring and fall when temperatures are milder. Summer can be extremely hot, and while winter is possible, conditions can vary. Always check the weather forecast before heading out.

Do I need any permits or pay entrance fees for this ride?

No, there are no specific permits or entrance fees required to cycle the Old Highway 91 Hill Climb, as it utilizes a public road.

What makes this route a good choice for road cycling?

This route offers a legal and scenic alternative to interstate cycling between St. George, UT, and Mesquite, NV. It allows cyclists to experience the natural beauty of the desert, including views of the Mormon, Virgin, and Beaver Dam Mountains, away from high-speed traffic. The significant 17-mile descent after the initial climb is also a major draw.

What should I know about the terrain and scenery?

The route traverses a desert landscape, including parts of the Shivwits Indian Reservation and the northwest corner of Arizona. You can expect paved surfaces on the old Highway 91, which acts as a frontage road. The scenery includes expansive desert views and distant mountain ranges.

How challenging is the Old Highway 91 Hill Climb?

The route is rated as moderate. It features a notable uphill section departing from St. George, followed by an extensive 17-mile descent. While the climb presents a challenge, the overall route is often described as 'chill' for experienced cyclists, though strong winds in the open desert can increase the perceived difficulty.

Are there any specific landmarks or viewpoints along the way?

The primary highlight is the Utah Hill Climb itself. From the crest, you'll be treated to panoramic views of the Mormon Mountains, Virgin Mountains, and Beaver Dam Mountains in the distance as you begin the long descent.

What kind of weather conditions should I expect?

As a desert route, expect dry conditions. Temperatures can be extreme, very hot in summer and potentially cold in winter. Wind can be a significant factor in this open, exposed area, potentially making the ride more challenging.

Is this route suitable for families or beginners?

While the route is paved, the initial climb and the potential for strong winds make it more suitable for cyclists with some experience. The 'moderate' difficulty rating suggests it might be challenging for absolute beginners or young children, especially on the uphill sections.

How long does it take to complete the Old Highway 91 Hill Climb?

The estimated duration for this 24 km (15 mile) route, which includes a significant climb and descent, is approximately 1 hour and 15 minutes for a racebike.
