We reached the Canyonlands National Park the night before, slept in the car and woke early. Went for a short hike of 1.5 km, then in the car and on we drove.
Reached the Arches NP around midday and decided to do a longer hike. 4.8 km but steep up the hill and that in a deadly midday heat. But the Delicate Arch was certainly worth it! After that we did one more shorter hike of maybe a km or so to the Windows.
All in all quite a nice hiking day :)
