Blackwater River State Park sits inland from Navarre, in the longleaf and magnolia country near Holt. The official Florida State Parks page describes a 590-acre park on one of the more pristine sand-bottom rivers in the country — dark water, pale bars, paddling, camping, and short trails. It is a half-day or overnight from Navarre, not a substitute for Gulf swimming.

Hours8 a.m. until sundown, 365 days. Ranger station 3–5 p.m. (Florida State Parks hours & fees page).
Day entry$4 per vehicle (up to eight people), honor box, exact change required. $2 for pedestrians/bicyclists and some discounted categories listed on the park page.
Camping$20 per night plus tax, plus a nonrefundable $6.70 reservation fee. $7 nightly utility fee for RV/cabin/bungalow/boat/yurt units; that utility fee does not apply to tent camping.
Late campersIf you will arrive after sunset, the park asks you to call 850-983-5363 between 3 and 5 p.m. Central for the gate combination.
Sites30 sites, 20/30/50-amp electric, water, sewer hookup, picnic table, fire ring and grill. Restroom with showers between loops.
RV length conflict on official pages. The park’s “Experiences & Amenities” page says sites can take 50-foot RVs. The “Camping at Blackwater River” page says the campground can accommodate tents to 35-foot RVs. We are not picking a winner. If you are in a long rig, call the park before you book, and read the site details in the reservation system.

What the river actually feels like

The water is tea-colored from tannins, not dirty. The bottom is sand. In summer it is a tube-and-kayak scene when levels cooperate. After heavy rain the river rises fast, wood moves, and local liveries sometimes shut down. Treat any social-media “it’s always easy Class I” claim as marketing. Check the USGS gauge near Baker (site 02370000) and call the park or a current outfitter the morning you put in.

The packing list that matches this park

The park does not hand you a branded merch list. This is the kit that matches the place: a tannin river, a shady campground, insects, and an honor box.

Cash, small bills

Honor box. Exact change. A $4 entry is a miserable surprise if you only have a card. Florida State Parks is explicit: correct change is required.

Closed-toe water shoes

Sandbars are friendly. The wood in the river is not. Cheap foam clogs float away. A snug water shoe you can hike a short trail in is enough.

PFD you will actually wear

If you paddle, Florida treats the kayak or canoe as a vessel. One wearable U.S. Coast Guard–approved life jacket per person; children under 6 must wear it while underway. A whistle. White light if you somehow stay out late — you should not.

Dry bag, not a “water resistant” tote

Phones die in tannin water the same as in salt. One small roll-top dry bag for keys and phone. A bigger one if you are camping.

Bug plan, not a citronella candle

River bottoms and dusk are midge and mosquito country. See the no-see-um guide for EPA-registered actives. Pack long sleeves for evening even in August.

Water and a way to carry trash out of day-use sandbars

There is a campground convenience note on third-party campground listings (ice, firewood). Do not assume a sandbar has a can. Pack water. Pack a trash bag.

Camping notes

Reserve through the Florida State Parks system (online or 800-326-3521). Florida residents can book campsites up to 11 months out; non-residents 10 months. Pets are allowed in designated campgrounds, not on beaches or playgrounds, with a maximum of four pets per site statewide. Alcohol is limited to reserved overnight accommodations and certain reserved indoor/pavilion contracts — not the river bank as a public picnic.

Florida residents 65+ or with qualifying disability documentation get 50% off the base campsite fee; reservation and utility fees are excluded. Bring the paperwork.

Unclear: maximum RV length (35 vs 50 ft on two official pages). River navigability changes with debris; we are not asserting a current log-jam closure without a dated park notice.
