Best time to visit Las Vegas for outdoor adventures
The best time to visit the Las Vegas area for outdoor adventures is in spring or autumn when the weather is warm, sunny and comfortable without the summer's high heat or the chill of winter nights. These seasons are a great time to travel if you're using Vegas as a starting point for hiking, exploring national parks and cruising down Route 66. Weather can still be variable during this time, so knowing what to pack for the Grand Canyon or Utah's 'Mighty 5' will help make for the best trip.
Mornings and evenings can be chilly during these times but are still ideal for camping in Utah's national parks or hiking the Grand Canyon's rim. With plenty of sunshine during the day and temps hitting 27°C, you'll have the best conditions for outdoor exploration.
