Can you bike from the campground to Zions National Park entrance? Is there a bike lane that you can safely ride to the entrance gate?

Yep! It's less than a half mile to the bike and walking entrance to Zion. We stayed at the RV Park and rode our bikes in every day!

Yes

Yes, but I like to bike up to the last parking lot where the Happy Camper store is, you can enter and pay there, and get to all the trails, and there is a place to lock up your bikes in case you want to take the shuttle.
