I was visiting my sister who just moved to the area. We did NOT hike to the top as we didn't feel we'd have time. We hiked around the trails a bit, though, and even carried lunch, thinking we'd find a great place to have lunch, but we didn't. We tried to stay on shady trails but you are definitely out in the sun some of the time, no matter what you do. We ended up eating our lunch down at the picnic tables. We were all confused by the word "arboretum" because we all thought that meant an indoor plant/flower place, but after looking up the definition we realized it can mean outdoor too. It wasn't as nice as I was led to believe but it was pretty easy hiking.
