BillE,
We lived on and cruised the Mississippi coast and barrier islands in 5 trailer boats for 22 years before retiring and moving to Pensacola in 2017. The Mississippi Sound is muddy and brown from the 5 rivers that empty into it (and occ the Mississippi river via a spillway). The 27 miles of sand beach along Highway 98 between Bay St Louis and Ocean Springs is dredged. The Gulf side of the barrier islands has clearer water and whiter sand, esp on incoming tides. We’ve hiked the perimeters of all of them many times and tent camped and boat camped on them hundreds of times.
Horn Island is an awesome pristine barrier island wilderness at 15 miles long by 2/3 miles wide and 9 miles out (can be rough). Only access is by private boat. The interior is filled with deep lagoons with alligators and impassible brier patches with only 2 cross-over trails (you’d never find these without local knowledge) and the Ranger dock trail. A perimeter hike was a two-day athletic summer adventure (we had to give up half-marathons in 2007, now it would take us 3-4 days). 2 lagoon outfalls could only be crossed at low tide.
But hey, a simple boat visit would entail anchoring at East or West end and walk only as much as you want, not the whole 31 miles with a CamelBak.
The Gulf Islands National Seashore (GINS) stretches 160 miles from Mississippi to Florida barrier islands. All the Florida sections can be reached by car via bridges (and you can take your 45 ft motor coach RV to camp at Fort Pickens). The Mississippi GINS barrier islands that can only be reached by boat include Cat Island (a portion is still privately owned), West Ship (a concession tourist boat leaves seasonally from Gulfport), East Ship, Horn, and Petis Bois.
I tried to outline some local knowledge tips regarding cruising the GINS in this thread in my April 22 post:

As we cruise-adventure and explore full-time now, we have yet to discover a gem that competes with Horn Island.
But we’ll keep looking for one! After Hontoon we’ll be exploring the Everglades and the 10,000 islands, perhaps ONE of them?
See you guys at Hontoon, and we’ll loan you our authoritative pre-Katrina Horn Island tome, which is still available but the price has doubled:
