We just got back from Memorial Day Weekend. We spent 4 days there and it was great! I also answered my own question about the bike, cart, or walk to the attractions: I wouldn't do it.... DH and DS rode the bike trail around the mountain and they had to walk their bikes up a hill or two. I would have attempted the bike ride but my handlebars loosened after 10 minutes of riding and DH forgot the allen wrench (which I'm glad he did
. I don't think I could have handled all those hills.
Stone Mountain is a beautiful park. If you camp there, you can purchase a one-day attraction pass and get the second day for free. This is what we purchased but the next day we upgraded (paid the difference) for an annual membership because we're planning a couple of trips within the year. Just one more trip will pay for it. Being only 4 hours away and low camping fee (Military, Fire, and Police discounts availabe) we can't pass it up.
The Attractions:
1) The Mountain itself is a work of art. At night they have a laser/fireworks show projected on the carving. During the day you can take the Skyride to the top or brave it like DS and DH did, walk it! They did it in 28 minutes. I took the easy way up, skyride up but I walked down. Not bad at all. Next time I will attempt the walk up. It's 1.3 miles. First timers may want to do the walk down first to check out the terrain. We met a woman on the way up who I wonder today if she made it. She was walking with her family up when DH and DS went up. She was by herself on our way down and she was resting. She was only about a quarter of a mile up the mountain and had started an hour earlier. Apparently her family left her. DH said she was with her husband and two kids. She was too scared of the skyride but if she made it to the top, I'm sure she overcame her fears. DH was afraid she was near heat exhaustion. We waited for a few minutes and chatted with her just to make sure she would be ok.
2) The 4-D Theater: Tall Tales of the South. Excellent. DH has a hard time seeing 3-D but he had no problems here. I guess it was the dark setting that accomodates his eyes better. And a lot of water splashes which DS enjoyed.
3) Ride the Ducks: My favorite! I kid you not...our captain was Captain Donald! The Duck is an amphibious truck invented by the military (DUKW). If you have children, he will let them drive the duck when in the water. Small children, I think 9 and under must wear a life vest. We didn't get wet, Captain Donald doesn't like getting wet
so he put the front windshield up when we took the plunge. This is an additional ticket to ride but it's worth it. Usually $12 per person but we only paid $6 because we had purchased the annual membership earlier.
4) The Crossroads: This is an area where you can see glass blowers, blacksmiths, candle makers and candy making. Yum....fresh homemade fudge! DH's eyes rolled back and his toes curled when he ate the mint fudge. They also have street performers, story tellers, and a talking fountain.
5) Stone Mountain Museum: This is a must do. I think this should be first on the list so you can get a better understanding and appreciation of the mountain.
6) The Train: Loved it. I've never had a train ride that I didn't enjoy...and this one was cute. Halfway through the ride, there is a stop along the way where some slapstick performers entertain you for a few minutes. The ride was beautiful and so relaxing.
7) The Great Barn: This was DS(11) favorite. Anything that allows him to shoot foam balls at his parents is a winner with him.
8) The Treehouse Challenge: This was a take-it-or-leave it for DS. He liked it but got bored very quickly. I think he still had the Great Barn on his mind because we had to head back there and do it again before the laser show.
9) Camp Highland Outpost: This is an obstacle course. At first we thought it was only for kids because no adults were doing it. DH asked if he could do it and they said sure. Following DH's lead, almost all the other Dads joined it. I saw a couple of them ask the castmember....ummm employee, if it was ok. It was fun but short lived too. Only once is enough.
And a word of advice, if you go during a peak time like we did, stake-out your spot on the lawn early in the day. Throw down a blanket and a cooler in the early afternoon. The lawn fills up quickly close to sunset. We got along the edge so we could get up and hit the concession and restrooms without having to go through an obstacle course.
Now just a brief word about food. Good 'ole southern cooking and some of the best rolls I've ever eaten are at Miss Katie's Restaurant. And DH loved their sweet tea. This was casual dining. We also ate another meal at The Commons. This is at the golf course not far from the campground. It's a little more upscale. I had the Crab Bisque and of course their Fried Green Tomatoes. It's by far the best I've had in a long long time. DH had their ribs and he devoured them like there's no tomorrow. DS said he wanted to be risky and try their kid's menu of Hot Dog Quesadillas. He made no mistake, he loved them.
I'll report tomorrow on the campground, the amentities, the comfort station, the noise, etc.
)...I would be scared to walk around in my camper with some of the stuff I saw!! Anywho..there is quite a bit of stuff to there to do, and some nights they do a laser show on the mountain which was pretty neat.
