Most people treat Sussex County as a summer destination. That’s their loss.
December through February is when the crowds disappear and the waterfowl arrive. Snow geese move through Prime Hook by the tens of thousands. Beaches are empty. Hiking trails are bug-free and tick-free. And the vehicle entrance fee at most state parks goes away for the season.
Here’s what’s open, what’s worth visiting, and what closes down until spring.
Waterfowl peak at Prime Hook
Winter is the reason birders put Prime Hook National Wildlife Refuge on their calendar. The refuge protects more than 10,000 acres, roughly 80 percent of it wetland, and in winter that wetland becomes one of the most active waterfowl staging areas on the Atlantic coast.
Snow geese and tundra swans move through in numbers that are hard to describe without sounding like an exaggeration. The snow geese guide covers the timing and viewing spots in detail. For the broader picture, Prime Hook has recorded over 245 bird species, and winter brings the spectacle that the mosquito-heavy summer months don’t.
Gordons Pond at Cape Henlopen is a second winter birding stop worth knowing. TrailLink notes it sits on one of four waterfowl migration “super highways” in North America, and the pond draws a wide variety of waterfowl through fall, winter, and spring. Herons are regularly visible there in winter.
The birding guide for Sussex County maps the full picture across seasons.
The shoulder seasons are when this county is at its best.
Practical details for Prime Hook in winter: the refuge is open every day of the year, from a half hour before sunrise to a half hour after sunset, with no entrance fee. The visitor center is open daily year-round from 9 a.m. to 4 p.m., weather and volunteer dependent.
Fowler Beach, closed for shorebird nesting roughly from March 1 through October 1, is accessible in winter. No dogs allowed, and access is walk-in only.
Quiet beaches and off-season access
Cape Henlopen’s beach is open year-round. Lifeguards and the fishing bait shop are not: the Fishing Center runs May 15 through October 1, and lifeguarded swimming at the two main beaches ends on Labor Day. What’s left in winter is a wide, mostly empty stretch of Atlantic shoreline.
The practical benefit is the fee window. Delaware State Parks charges a seasonal vehicle entrance fee at its coastal parks. That fee runs roughly spring through fall; winter visitors often find the entrance station unstaffed and the gate open.
The official Delaware State Parks site is the only reliable source for exact dates and current rates, which change year to year.
The fishing pier at Cape Henlopen is a different matter. According to Wikipedia’s Cape Henlopen article, the bay fishing pier is open 24 hours, year-round. Winter surf fishing has a following of its own.

The Cape Henlopen guide covers the full park layout, parking options, and what’s available beyond the summer season.
Winter hiking
Bug season at Prime Hook runs June through September, per USFWS. That means the eight trails on the refuge are effectively bug-free and tick-free from October through May. Winter is arguably the best hiking window at Prime Hook: the vegetation is lower, sight lines into the marsh are longer, and the birding is better than any other season.
At Redden State Forest, the calculus is straightforward. More than 14,000 acres across 18 tracts, free to enter, open year-round. The Headquarters Loop runs 4.0 miles of packed earth through hardwood and loblolly pine.
One rule applies to Redden in winter: Sunday hunting is prohibited on all Delaware State Forest property, per the Delaware Forest Service. That standing rule means Sundays are the safe day to hike during hunting season; wear blaze orange on weekdays in fall and winter when hunting may be active.
Cape Henlopen’s trail network stays open in winter. Gordons Pond is accessible and at its quietest. The Prickly Pear Trail near Ocean View is worth a check before visiting: according to TrailLink, it closes for hunting season, so verify DNREC dates first.

What closes in winter
The boating concessions shut down in fall. Trap Pond State Park’s rentals, which include kayaks, canoes, rowboats, pedal boats, and paddleboards, are a summer season operation. The pontoon tours on the pond run summer weekends and holidays, per Delaware State Parks. If you visit in the off-season you’ll need to bring your own craft.
The kayak rental outfitters that serve the county’s coastal paddling spots operate on similar schedules. The kayak and canoe rentals guide lists which operators run and which go quiet after Labor Day. The broader paddling guide for Sussex County covers access points that are reachable with your own gear year-round.
Nature centers cut back hours or close days. Trap Pond’s Baldcypress Nature Center is closed Mondays and Tuesdays, per TrailLink’s American Holly Trail page, and its spring and summer seven-day schedule doesn’t continue into the off-season. The Seaside Nature Center at Cape Henlopen also reduces its hours; check the Cape Henlopen park page for current hours before planning a visit that depends on it being open.
The Bob Trail loop at Trap Pond has no seasonal closure, according to TrailLink’s Bob Trail page. You can walk the bald cypress swamp in January. The Trap Pond water trails guide covers the winter look of the pond: bald cypress is a deciduous conifer, and the rust-orange needles drop in autumn, so the pond has a different character from November through March than it does in summer.
Dressing for a Delaware coast winter
The coast adds its own conditions to what the calendar says. Wind off the Atlantic and Delaware Bay can make 35F feel significantly colder on an exposed beach or open trail.
Days are short in December and January. Plan your turnaround time around sunset, not arrival time.
Layers are more useful than bulk. The trails here are low-elevation and flat, so physical output is lower than on hilly terrain. That means you’ll cool down faster at rest stops.
A few specific notes:
- Cape Henlopen beach: wide and exposed. Wind speeds there often run higher than the inland forecast.
- Prime Hook: the dike trails and marsh edges offer less wind shelter than the wooded upland trails. The Photo Blind provides a windbreak while watching.
- Redden State Forest: the tree canopy cuts wind significantly on the HQ Loop. It’s often warmer in the forest interior than at the coastal parks.
Daylight and road conditions (fog is common on cold mornings near the bay) are practical reasons to check conditions before leaving, especially for early starts.
Frequently asked questions
What is there to do outdoors in Sussex County in winter?
The main draws are waterfowl watching at Prime Hook and Gordons Pond, hiking on bug-free trails at Prime Hook and Redden State Forest, and quiet beach access at Cape Henlopen. Cape Henlopen’s bay fishing pier stays accessible year-round, any hour. Rentals and guided tours are largely unavailable from November through March, so activities that depend on outfitter equipment require planning ahead.
Where are the best spots to see snow geese and waterfowl in winter?
Prime Hook National Wildlife Refuge near Milton is the county’s primary waterfowl destination. The snow geese guide covers viewing spots and timing. Gordons Pond at Cape Henlopen is a secondary stop. Both are free to enter. The birding guide covers additional winter species and locations across the county.
Are Sussex County state parks free in winter?
Delaware State Parks charges a seasonal vehicle entrance fee, which applies roughly spring through fall at the coastal parks. Winter visits often fall outside the fee season. The exact dates and current rates are on the official Delaware State Parks site. Prime Hook National Wildlife Refuge and Redden State Forest have no vehicle fee at any time of year.
Is winter a good time to hike in Sussex County?
Yes, for two reasons. Bugs and ticks are at their peak from June through September at Prime Hook, per USFWS; winter hiking there is free of both. Crowds on the coastal trails drop sharply after Labor Day. The main adjustment is checking hunting calendars for Redden State Forest and the Prickly Pear Trail before visiting on weekdays in fall and winter.
What closes for the winter season?
Boating rentals and pontoon tours at Trap Pond close after the summer season. The Cape Henlopen Fishing Center closes October 1. Lifeguarded swimming ends on Labor Day. Nature center hours at both Trap Pond and Cape Henlopen are reduced from their spring and summer schedules. Hiking trails, the fishing pier, and the wildlife refuge remain accessible. Check the park pages for current hours before any trip that depends on a facility being open.
