Is there parking available for a semi tractor and trailer 70 feet long so we can do tour or hike in park?

You may fit in a side-of-the-road pull-out, but it may be hard to find place. We're 60 feet long and unhitched to go hike.

Some of the trail head parking areas are large. Best to check with park service before parking across multiple spots though.

That's all good advice given for parking... enjoy your time hiking🖒
