Stargazing

Hi everyone! My friends and I are going at the end of the month and it’ll be our first time! We reserved a stargazing with yosemite conservancy and would like to know how the hike is? There’s not a lot of info about the activity, but they did mention the hike is easy. Just wanted to know if it’ll be on a paved trail or if there’s gonna be a bit of elevation?

Thank you!
