Last weekend, I went with the NWA Hiking Group (from Meetup.com) to Devil's Den. We went on trails and wandered off of them as well. It was great exercise and I enjoyed meeting so many outdoorsy individuals.
This weekend, after attending a cooking class in Eureka, I drove down to Withrow Springs and hiked the War Eagle Trail. Beautiful area! I will have to go back when I can spend more time.
