Are dogs allowed

Maximum of 2 dogs in air conditioned R/V's. NO dogs in tent sites. MOST trails (and the park shuttle) do not allow dogs in Zion Park.

yes, but many trails are not open to them

You can only make the trail a long the river near the entrance

Yes. Took mine in April. No problem. However, dogs are not allowed in all areas of Zion National Park. Found a great daycare service for pets just outside of downtown. https://www.doggyduderanch.com/

For sure. There were dogs all over the place

Yes

I believe so.
