I loved Reedy Creek when I lived in Charlotte and would make frequent trips to take my four legged pal there. The dog park is a large space. it used to be membership only which made it awesome because the real dog lovers would pay the nominal fee for a pass. I believe it is now open to the public which makes it a lot more of a quesiton mark but still enjoyable.
The hiking trails are great and there is terrain for everyone. I took my now fiance on our first date there.
