15Zion National Park, Utah
Last but not least on our list is Zion. Temperatures here never go higher than 84 degrees Fahrenheit in May. Indeed, it’s dry and sunny and the weather is cooler at higher elevations. The majority of the hiking trails here are open, and you can enjoy them without the summer crowds and scorching heat.
Nevertheless, always check the park’s official website. Even if the weather is fine, sometimes trails are closed due to construction efforts or even flooding. In May the Virgin River has high water levels so it’s also a great time to check out the waterfalls.
Unfortunately, May is also the start of the peak season, so while all facilities are generally open, the park can still be quite busy even if school is still in session. Avoid weekends if you can; especially Memorial Day weekend. Start your day as early as possible too!
