2-Day Loxahatchee Slough Stand-Up Paddle and Wildlife Circuit

The first alligator appears before you’ve paddled 200 yards. It’s on the bank to your left, 10 feet long, absolutely still, watching you with the expression of something that has been doing this far longer than you have. You give it room. It does not move. This is Loxahatchee Slough, and you are clearly the newcomer.

Grassy Waters Preserve encompasses more than 12,000 acres of freshwater wetlands, pine flatwoods, and slough habitat in western Palm Beach County — the largest undeveloped freshwater wetland remaining in Palm Beach County, and one of the few places you can get genuinely lost in wilderness without leaving the suburbs. The Loxahatchee Slough itself is a tributary watershed of the larger Arthur R. Marshall Loxahatchee National Wildlife Refuge to the west, and feeds the wellfields that supply drinking water to most of Palm Beach County. The ecology here is not decorative. It is working landscape.

“Urban wilderness” sounds like marketing copy. Then you paddle in and lose cell service by mile one.

Overview

Grassy Waters Preserve (8100 Northlake Blvd, Palm Beach Gardens, FL 33418) is the anchor for both days. The preserve has a dedicated canoe/kayak launch on the east side, with parking, restrooms, and a trailhead. The paddling is sheltered, shallow (typically 1–4 feet), and slow-moving — appropriate for beginners and excellent for wildlife observation.

Best season: Winter and spring (November–April). Water levels are highest after the summer wet season, making October–November ideal for paddling depth. January–March brings the lowest mosquito pressure and the highest concentration of wintering birds. Avoid June–September: afternoon thunderstorms are daily, water temps push into the 90s°F, and alligator nesting activity peaks.

Difficulty: Easy. No significant current, no open water, no portages. The main physical challenge is heat management — this is West Palm Beach, and even in February, you’ll be on the water under full sun.

Base camp: Palm Beach Gardens or Jupiter — both are 10–15 minutes from the Grassy Waters launch. Multiple hotel and short-term rental options at $80–$200/night range. Camping is not available at Grassy Waters; nearest camping is Jonathan Dickinson State Park (~25 miles north).

Permit/access fee: Free. Grassy Waters Preserve is managed by the City of West Palm Beach and is open 7 days a week, dawn to dusk. No launch fee, no reservation required.

Day by Day

Day 1 — Grassy Waters Preserve Slough Loop

Launch from the Grassy Waters canoe/kayak launch on the preserve’s east boundary. The launch is signed from Northlake Blvd — look for the brown preserve sign, then follow the access road to the parking area. The put-in is a gentle bank with good egress.

Paddle west into the slough channel. The water is dark with tannins — stained the color of strong tea from decaying plant matter, which is normal and healthy. Depth is typically 2–3 feet in the main channel, shallower along the banks where alligators bask and herons hunt.

Mile 0–2: The first stretch is the best for alligators. You will see them. Winter mornings, they’re on the banks warming up; afternoons they’re in the water. Tricolored herons and great blue herons are constant companions along the whole route. Watch for anhingas drying their wings on cypress branches — they lack the waterproofing oil of most water birds and must spread their wings to dry after diving.

Mile 2–4: The channel opens into broader marsh areas with emergent vegetation. This is otter territory — river otters work the slough heavily and are most active in early morning. Look for their V-wake ahead of you in the dark water. Softshell turtles are common; Florida cooters bask on every available log.

Mile 4–6: Loop back via the eastern flats. Purple gallinules work the lily pads; limpkins (a distinctive wading bird, makes an eerie wailing call) forage in the shallower areas. The return section in afternoon light is excellent for photography — the vegetation channels the light and the birds are active before dusk.

Total paddle: 6–8 miles, 3–4 hours at a wildlife-watching pace. Return to launch by 4 p.m. to stay clear of dusk — alligator activity increases at low light.

Day 2 — Loxahatchee Slough Northern Section

Day 2 extends west into the more remote sections of the slough system. Re-launch from Grassy Waters and paddle northwest toward the deeper interior channels. This section sees fewer paddlers and proportionally more wildlife.

Morning target — the cypress strand: At approximately mile 2–3 heading northwest, the open marsh transitions to a cypress strand — standing cypress trees draped with Spanish moss, with the water darkening to near-black under the canopy. Paddling through this is one of the defining Florida wilderness experiences. Temperature drops 5–10°F under the canopy. Wood ducks and hooded mergansers winter here; prothonotary warblers arrive in spring (March–April) and are among the most vivid birds you’ll see anywhere.

Mile 3–5: The remote interior. No development visible in any direction. This is the closest thing to Everglades-style paddling without the 3-hour drive south. Bald eagles nest in this section of the slough — scan the tops of the tallest cypresses for the white head. Roseate spoonbills are occasional visitors from November through March.

Afternoon return: Retrace your route back east. The return paddle in afternoon light shows the marsh from the opposite angle — useful for spotting animals you missed outbound. Exit the water by 3:30 p.m. at the latest; afternoon thunder cells build by 4–5 p.m. even in dry season.

Total paddle: 8–10 miles, 4–5 hours.

What to Pack

• SUP board: Wide all-around or touring board, minimum 30” wide. Inflatable SUPs work fine on this flat water. Narrow performance boards are an unnecessary balance challenge when you’re watching wildlife.
• Paddle: Standard SUP paddle. Carbon is lighter over 8 miles; aluminum is fine if you’re renting.
• PFD: Required by Florida law for anyone under 6. Required by good sense for everyone else. Inflatable belt PFDs are comfortable and barely noticeable.
• Leash: Attach to your ankle. If you fall in tannin water surrounded by alligators, you want your board immediately available.
• Water: Minimum 3 liters per person per day. There is no potable water on the water trail. The dark slough water is not safe to drink untreated.
• Reef-safe sunscreen + sun shirt: No shade on the open marsh sections. A long-sleeve UPF shirt is better than sunscreen alone — the water reflection doubles UV exposure.
• Insect repellent: Even in dry season, mosquitoes are present near the vegetated banks. DEET or picaridin. Permethrin on clothing if you’re doing any bank exploration.
• Dry bag: Phone, car keys, wallet, snacks. Everything gets wet eventually.
• Binoculars: The wildlife density here justifies optics. Even 8x32 compact binoculars are transformative for bird ID.
• Polarized sunglasses: Essential for cutting surface glare and seeing into the dark water.

Getting There

Grassy Waters Preserve canoe/kayak launch: 8100 Northlake Blvd, Palm Beach Gardens, FL 33418. From I-95: take Exit 79A (Northlake Blvd West). Head west on Northlake for approximately 4 miles. The preserve entrance is on the right (north side) before you reach the Florida Turnpike interchange. Look for the brown county preserve sign.

From the Florida Turnpike (SR-91): Exit 109 (PGA Blvd), head east to Military Trail, north to Northlake Blvd, then west. The preserve entrance is on the left.

Parking is free, lot opens at dawn. No shuttle needed — this is a loop paddle, not a point-to-point.

Nearest gear/rentals: Jupiter (15 min north) and Palm Beach Gardens (10 min east) both have outfitters. Call ahead on weekends.

Honest Caveats

Heat. Even in February, mid-day temperatures on the open marsh can hit 85°F. In October and November — technically “fall” but still hot — you’ll be paddling in high humidity with limited shade. Schedule launches before 8 a.m. and plan to be off the water before early afternoon if the forecast shows heat index above 95°F.

Mosquitoes and biting insects. Even with DEET, the vegetated bank sections in any season carry biting insects. This is not optional Florida discomfort — it is the price of paddling in a functioning wetland. Bring repellent; accept some bites.

Alligator encounters. You will see alligators. Most encounters are non-events. Do not swim. Do not dangle hands or feet in the water. Do not approach a gator to photograph it. Do not, under any circumstances, feed wildlife. If a gator follows your board, paddle toward open water and give it a wide berth — most “following” behavior is curiosity, not predation.

Water levels vary. The slough is fed by rainfall. In drought conditions (typically March–May), water levels drop significantly, and sections of the slough become too shallow to paddle. Call the preserve at (561) 804-4985 before your trip to confirm current conditions. Low-water years can make Day 2’s interior sections impassable.

No lifeguards, no cell service. The interior sections of the slough have limited to no cell coverage. Tell someone your float plan — launch time, expected return, vehicle description. Carry a charged phone and a whistle at minimum. For multi-day trips or remote sections, a personal locator beacon (PLB) is worth the weight.

The preserve is closed at dusk. Rangers enforce this. Do not still be on the water at sunset.
