Went up the Thomas Point Trail, cross country on the rim to the Telephone Trail, then down. This is a great loop hike, but finding the Telephone trail on top of the rim can be tricky. There are two large cairns once you're close to the Telephone Trail. Once you find them walk straight out towards the canyon staying on the right side of the ridge you're on and you'll quickly spot the trail.
I recommend going DOWN the telephone trail unless you want a really good workout! We only saw one other group of hikers this day. It got pretty warm by the time we finished at around noon.
