Traveling with very young children (ages 4 years, 3 years, and 3 months) was a fun experience for me. Children definitely travel at a different pace than adults. Sometimes their pace is slower--like when 4-year-old Debbie wanted to stop to pick up many beautiful pebbles along the trail to view Delicate Arch. Here's a photo of them there, with Debbie's shirt full of pebbles whose beauty I never would have noticed without her.
Sometimes children travel at a faster pace than adults, like when 3-year-old Anna wanted to run the entire way back to the parking lot from the Pine Tree Arch. (She and Debbie were well-rested and happy after spending an hour or so playing in the sand at the foot of Pine Tree Arch where we stopped for lunch. Suzy was kind enough to wait with the girls there while I made the rest of the hike up to Landscape Arch). Here's a photo of Suzy and the girls on the Pine Tree Arch trail. I think the other tourists we met along the trail were charmed by the fact that Anna brought along her blanket and Debbie brought along her umbrella...one of the tourists commented that he wished he'd brought his blanket too!
