If you’re thinking about visiting Bryce Canyon and Zion, you’re in for a real treat. Both Utah National Parks are breathtaking, and timing your visit can make your trip even more memorable.
If you can avoid spring break, then April and May are considered some of the best times to visit Bryce Canyon for moderate temperatures with fewer crowds.
As the summer crowds thin out and temperatures cool down, you can enjoy stunning views at Bryce Canyon in the fall without having to deal with the heat or huge numbers of tourists.
Springtime at Zion varies quite a bit from month to month. In early spring it's wise to pack for all types of weather, you never know when it will change.
