A friend of mine sent me this info about the area. It looks really useful so I am doing a cut-n-paste to share.
Someone of your group asked about wireless. Last year I used WiFi in the lobby of the lodge, but it is unlikely to be available in the campground. It is a pretty long walk to the lodge from the campground, along a backroad. Someone earlier posted the link for the park map.
There is a meeting room at the end of the lodge, at the entrance to the lobby, just inside the double doors. If the door to the meeting room is open, it is a good place to use the computer, and there are electrical outlets.
The Wildflower Weekend is a joint activity of Natural Bridge State Park, and the Kentucky Native Plant Society. Kentucky Native Plant Society Main Page
Wildflower Weekend is an excellent program, to locate and observe the wildflowers that bloom briefly at that time. There are activities in the morning, afternoon and evening on Friday and Saturday. There is a $10 fee for participation in the Wildflower Weekend for adults, $3 for 13-17, and free for pre-teens. There is a similar program at Gatlinburg, that charges $30 for one day, and $50 for to to four days, so the fee is modest. The evening programs are at the Activities Center, that is on the map. The walkway from the Activities Center to the Lodge is a unique, elevated walkway over the steep hillside, and is a curiosity by itself. Notice the moist feeling of the micro-climate along the walkway.
The nature hikes assemble at the lodge. They are to different places in the park, and to the nearby Red River Gorge, and the national forest. The walks are led by guest naturalists, as well as those from the park. Most of the walks will be to identify native wildflowers, but some may be to identify trees, or some of the many non-native plants.
Some of the walks may look for birds, but in most cases, the naturalists are able to identify a lot of things. Participants will range from plant experts to visitors to the state, who know nothing of the wildflowers in Kentucky, but you can always get questions answered. The walks usually involve some excellent scenery. Most walks are not strenuous, but you should ask the naturalist on the walk before signing up at the lodge. There will be different flowers on each walk. There are some native, hand-sized orchids, particularly on the Whittleton Arch Trail, but they are fairly rare. Flowers along the creeks will be very different from those in drier areas along the ridges, so each trail has different flowers.
The park has nature hikes by naturalists throughout the year, that are at no charge, and they may do that for your group, but most likely the naturalists will be leading Wildflower Weekend walks. So it might be better to pay the $10 fee, and take one of the walks Friday morning, and see what you think. I saw the schedule that your group had planned, but you are at the park at a unique time, for a unique event, and it would be worth taking advantage of it. You might look at doing more of your group activities on Wednesday and Thursday, and leave time Friday and Saturday for the Wildflower Weekend activities. Since a number of your group are from out of state, this would be an opportunity to see some of Kentucky, and to learn about Kentucky wildflowers, although many of the flowers have a wide range.
One of the walks will almost certainly be to Natural Bridge, and you should take that, or do it on your own. When you get to the top of Natural Bridge, cross the bridge, and continue around the ridge, past the Sky Lift to the view point. It gives a good view of Natural Bridge. The viewpoint is just up the hill from the lodge. There are other walks in the park, but the walk to Natural Bridge, and around the ridge to the view point, are a must, for the scenery, and the flowers.
The "Rock Garden" is one of the best places for viewing wildflowers, and I would do that as well.
You should consider having a meal at the restaurant at the lodge.
They could accommodate your group, but you should give them advance notice, if more than a few go to eat. They have a buffet and menu.
I would take good walking shoes, and hiking boots are good, but tennis shoes work as well. Most walks last two or three hours. Take a camera that can take closeups. Take a bottle of water with you, and a hat for the sun, and whatever you might need for a three-hour walk. If you want to help your memory, take a pencil and paper, to write down some of the flower names.
