I don't like to tout National Parks because there is plenty of great free stuff to do. However, the Peekaboo Loop accessed from Bryce Point in Bryce Canyon National Park is the most awesome hike in the most eye-popping N. P.
Hiking in Bryce is no walk in the park. The hoodoos reflect the sun's heat uncomfortably on uphill grades. High elevations and natural ups and downs make this a demanding hike. The park recommends 3-4 hours, we did it in 2 1/2. I could not recommend this on a hot summer afternoon.
This loop and access lets one see the entire Bryce Canyon Amphitheater, worthy of the name. And see the Wall of Windows. The Bryce Point access is not always open, dependent on weather. Peekaboo can also be accessed from Navaho Loop (still great but not as).
We prefaced this 5 1/2 mile hike (rated strenuous) with the 1 mile Bristlecone Loop at the top of the paved 18 mile park road. These trees are always cruelly twisted but they like it like that-bad weather is good for thousand year life spans apparently. We didn't need to do this, as Peekaboo had a few specimens. But it's an extra mile if you want it.
So go on a free National Parks day.
Red Canyon next door in Dixie National Forest has free access.
