My kids, husband and I have to visit mt. Nebo every fall. You can always find a hike the perfect length. There a great beginners Mt Bike trail. It is a special place to us always b/c my husband proposed to me at Sunrise point. Some days, there are hang gliders jumping off the mountain--very neat to watch.
We stayed in a cabin at Mount Nebo State Park with our kiddos. The Park has awesome trails and gorgeous views. While hiking on the trails, we also did some geocaching. Many of the geocaches were out of our physical range (we're not very brave). But the caches we did find were fun to find. I just wish we had more days to spend here. This State Park is gorgeous and definitely worth the trip!
