We had some out-of-towners come in for Spring Break. We enjoyed a brief hike in Snow Canyon State Park namely Jenny's Canyon (a slot canyon), with my BIL's family. Later that week we intended to take my brother and his family there but found out it was closed until June 1 (starting the day after our visit earlier the same week).
Of course, with any out-of-town visitors to St. George, you have to take them to Zion National Park. The crowd was not too bad considering Spring Break and the weather was nice - at least, in the sun it was. It was kind of cool in the shade. There were still places in the park with snow.
