I just ran across your post. There are a ton of things to do in the area, near the beach, without having to go much above your ankles in the water. I assume since this is under the FWB site, that you are staying in FWB. I just ask that because I live in FWB, but I personally think Destin is much better. It has really built up over the past many years and so much of it is new.It also has the better restaurants. Boat charters and boat rentals will come more out of Destin than FWB. There is an area in the water, called Crab Island. (you can look it up on line). It is very popular, and often crowded, but some people just love to visit and play there while here. Destin also has the Big Kahuna's which is a popular water park in the area. Both FWB and Destin have miniature golf course for your evening entertainment. FWB has The Gulfarium (it is very small). There are a lot of water sports available. Trip Advisor does not have as many listings as what are actually available, so just look around on the web and compare for pricing. Also pay attention. Some places actually want you to make reservations in advance, so beware that you may miss out on an activity you wanted to do if they are already booked for while you are down here.
Someone else mentioned 30A. Anyone visiting, this is really a must!! I grew up in this area, and I love to visit here. 30A is about 15 minutes past Destin, going towards Panama City. It is rather long. I would suggest to not start at the first part of 30A, rather keep driving on hwy 98 and turn right on either 283 or 395 and cut into 30A just to save time (traffic is 30mph on 30A and many stop signs). You can look up 30A on line. You will come up to towns like Seaside, Alys Beach, Rosemary Beach. Darling seaside towns. You can drive through to just look, but many people rent bikes. There is the Timpoochee Trail that run the full length of 30A and is a nice wide bike trail. There are umpteen places to rent a bike there. Seaside often as shows or festivities, so if you want to park there, I would suggest getting there by 9am, or it will be hard to find a spot. Weekends are busier in these little towns, than weekdays. It is fun to ride your bikes down there, and see the gulf as you are riding.
If for any reason, you have all had too much sun, and you need something out of the sun, there are some other places to go. Unfortunately, outside of the beaches, I don't find a ton of activities to do. You usually have to drive a bit to get there. You didn't mention what age your girl was, so not sure if these are age appropriate. But if you drive about 30 minutes west of FWB to Gulf Breeze we do have The Zoo. Not a large zoo, but has a good variety of animals. If you guys are in to any sort of history, FWB does have an armament museum, and an hour to the west is Pensacola and they have the best air museum around. If you go on a Wed, you may even get to see the Blue Angels practice (for free).Those are just some of the more popular attractions here (outside the beach and water sports). On the way to P'cola is Fort Pickens.
Sounds like you and your family are nature people. This is not the beach, but one other suggestion if you were looking for a little time in nature. Some of the State Parks off of 30A do have nature trails, but during the summer months, the horse flies can be vicious. So slather up with bug spray if you dare. But I was also going to suggest the Blackwater River State Park in Milton (about an hours drive from FWB). You can rent kayaks and they take you up river and you can float downstream. The area is very pretty and will give you an idea of what old florida looked like. I went on a trip there May or June.The river current was fast enough, you barely had to paddle during part of the trip. It was very hot outside but the river is fed from springs and was ice cold. It was wonderful. Just a thought.
Looks like you stated you will be staying in a condo on the beach. Hopefully you will have a nice area without too many neighbors that you can enjoy a peaceful time. We have beautiful white sand, that feels so soft on your feel. And the water can be the most gorgeous color. I think just enjoying the view will make your trip to the beach this year worth it.
Even though the mountains are gorgeous, everyone has to spend some time at the beach, and we truly have some of the nicest beaches in Fl (believe me, I have seen most of what F has to offer in that department). I think once you see the beauty here, you will truly be glad your daughter pushed you to come here. Even if you never actually venture into the water. I also think you may love the towns off 30A. But whatever you guys decide to do, hope you have fun!!
