Dan Nicholas Park http://www.dannicholas.net/
This was such a fun and inexpensive place to spend the day. It's near Salisbury and features a lot of activities. We enjoyed a carousel, train ride, gem mining, petting barn, nature center, aquarium, picnic area, mini golf, and a great playground. Less than $10 a person for everything! They also have paddle boats and a water plaza area for warmer days. This was one of the coolest parks we've been to... very relaxing... spread out under a canopy of trees in a cool forested area. Has a mountain campground feel. I highly recommend for a day trip!
We took a Sunday trip to see the leaves in the Boone area and rode to Blowing Rock. The kids loved posing on the rocks for pictures and walking the easy little trails. The view from top was really breathtaking and they loved looking in the viewers. Then we headed to Linville Caverns. This place was a hit! A 30 minute tour takes you through a real "cave" as the kids called it. They learned about stalagmites and stalagtites and saw real hibernating bats as they meandered through the cavern. It's just slimy and spooky enough to be fun but not scary. Great experience for kids.
Train Ride to the State Fair http://www.bytrain.org/fall/2010statefair.html
This past Wednesday, we took the Amtrak train from Greensboro to the State Fair in Raleigh. The fair is always fun, but adding the train ride really pumped up the excitement factor. The little ones LOVED going to the depot and boarding the train. The ride itself was a lot of fun and the dining car was a special hit. The train stops right across the street from a fair gate and has a nice covered area for waiting. The "waiting" was a little tedious coming back since the train was a little late but all in all, it was a fun experience I would do again. I recommend bringing some little toys or books for entertainment if there is a wait or if the train ride loses its luster. We played cards, travel size games, and of course my little techie commandeered my iPhone for a session of Glass Tower.
Hope this gives you some new ideas for the season.
