The shoulder seasons are when this county is at its best.
Fall (September through November) is when the crowds thin, the bugs stop, the temperatures drop into hiking range, and the county’s most distinctive natural event begins: the bald cypress turning color at Trap Pond.
This page organizes what the season actually offers, activity by activity, with the timing facts sourced from the parks and agencies that manage them. It isn’t an events calendar; events change year to year. The seasonal patterns here are stable enough to plan around.
Fall color at Trap Pond
Trap Pond State Park near Laurel holds the nation’s northernmost natural occurrence of bald cypress, a species whose range extends south to Florida and west into Texas.
What makes fall the right time to go: bald cypress is a deciduous conifer. As the NPS describes it, the dense stands at Trap Pond turn to glossy cinnamon in the crisp autumn air before dropping their needles, hence the name “bald.” No other season produces that color on the water.
Delaware State Parks runs narrated Fall Foliage Pontoon Tours at Trap Pond in October. Past seasons have offered guided evening tours; pricing has been adults $15 and children 12 and under $10, plus the park entrance fee, with online registration required. Check the park calendar for current dates, as scheduling varies annually.
The regular summer pontoon boat tours run on weekends and holidays, per Delaware State Parks, but the fall foliage tour is a separate ticketed event at a different price point.
Nearly nine miles of canoe and kayak routes run through the pond; the Trap Pond water trails guide covers all of them if you’d rather see the cypress from a paddle than a pontoon. Check the current park calendar on destateparks.com before a November visit, as hours shift after the main season ends.
Hiking in cooler weather
September through November is the county’s most comfortable hiking stretch. Temperatures are lower, the humidity that defines a Delaware August is gone, and the biting flies and mosquitoes that USFWS flags as heavy at Prime Hook from June through September have cleared out.
That changes the calculus at Prime Hook National Wildlife Refuge, a site worth visiting in any season but genuinely easier to enjoy once fall arrives. The refuge provides habitat for over 245 species of birds and offers free trails totaling roughly 7.5 miles, all open to leashed dogs.
Redden State Forest is another fall target; its trail network covers more than 44 miles across 18 tracts, with free access and no entrance fee for day use.
One planning note for Redden: Sunday hunting is prohibited on all Delaware State Forest property, per the Delaware Department of Agriculture. Sunday is always safe for hikers in the forest, year-round. Weekday visits during hunting season are a different matter; read the section on hunting below.
The full picture of what’s walkable in the county is in the Sussex County hiking guide, which covers distances, surfaces, fees, and dog rules for all 19 named public trails.
Beaches and dogs after the season
The swimming beaches at Cape Henlopen and Delaware Seashore follow Delaware State Law: pets are prohibited from all swimming and sunbathing beaches from May 1 to September 30. The ban lifts on October 1, per the Delaware State Parks pets policy.
That makes October the first month dog owners can bring their dogs to the beach at Cape Henlopen, via the pedestrian dune crossings at designated parking areas. The crowds that define July on the Rehoboth boardwalk are also largely gone by then. Cape Henlopen’s lifeguarded swim beaches are staffed only Memorial Day through Labor Day, so the fall beach has a different feel from the summer one: quieter, less structured, and windy in the better sort of way.
For dog owners, the dog-friendly trails and beaches guide covers every park’s rules in detail, including the year-round exceptions (Beach Plum Island is closed to pets regardless of season).
Wildlife arriving
Fall is also when the county’s waterfowl season starts. Gordons Pond at Cape Henlopen provides habitat for a wide variety of waterfowl through fall, winter, and spring, according to TrailLink’s Gordons Pond trail entry. Delaware Greenways describes the trail corridor as one of only four waterfowl migration superhighways in North America.
Waterfowl numbers build through November. The birding guide covers the refuges and ponds where fall migration concentrates, and the snow geese guide covers the Prime Hook arrival specifically, which is a late-fall and winter phenomenon.
One planning note for Gordons Pond: sections of the Gordons Pond Trail may close seasonally for nesting or hunting. Check with Cape Henlopen State Park before visiting, as TrailLink’s trail entry recommends. A quick call or check of the park’s site before you go is the practical move.
Hunting season opens
Delaware hunting seasons generally begin in September and run through early February of the following year, per the DNREC hunting seasons page. That overlap with fall hiking isn’t a reason to avoid the county’s public lands, but it is a reason to know which trails sit inside or near active hunting areas.
Two places where the intersection is direct:
The Prickly Pear Trail at Delaware Seashore State Park closes for hunting season. The trail itself, not just the surrounding area. Per TrailLink’s Prickly Pear page, visitors should check DNREC dates before planning a fall or winter visit. This is one of the few county trails with an outright seasonal closure.
Redden State Forest is open to hunting on weekdays during the season. Hikers on weekday visits should wear blaze orange; Sunday is prohibited for hunters throughout the state forest and is always hiker-safe.
The hunting seasons and trail safety guide covers the specific dates, the orange rule, and which areas require the most care in fall. Every fact here links to its official source; the DNREC seasons page is the one to bookmark.
Fees and timing
Most Delaware State Park entrance fees apply through the end of November. The Cape Henlopen campground, for example, runs March 1 through November 30, with reservations required, per the Cape Henlopen State Park entry on Wikipedia (sourced to the park’s own pages).
After November 30, many park amenities shift to off-season access. Vehicle entrance fees at most state parks run March through November; exact end dates vary by park and year. Check the current rates and dates on the Delaware State Parks site before planning a late-fall trip.
Free-access spots are unaffected by the fee season: Redden State Forest, Prime Hook National Wildlife Refuge, and the Georgetown-Lewes Trail charge nothing for day use in any month.
Frequently asked questions
Is fall a good time to visit Sussex County outdoors?
Yes, and by several measures it’s the best time. Temperatures are in the comfortable hiking range, the summer insect peak at Prime Hook has ended, beach crowds have thinned, and the bald cypress at Trap Pond puts on its only seasonal color display. The main consideration is hunting season, which opens in September; knowing which trails are affected takes a few minutes of planning.
When is the fall foliage at Trap Pond?
The bald cypress at Trap Pond turns in autumn, typically through October and into November. Delaware State Parks has run Fall Foliage Pontoon Tours in October; the 2023 editions ran October 18 and 19. Dates and pricing change annually, so check the park’s calendar on destateparks.com for the current season’s schedule.
When can dogs go back on the beaches in Sussex County?
October 1. Delaware State Law prohibits pets on all swimming and sunbathing beaches from May 1 through September 30. The ban lifts the next day, and access from October through April is through pedestrian dune crossings at designated parking areas. The dog-friendly trails and beaches guide has the park-by-park details.
Do I need to worry about hunting season on the trails in fall?
On most county trails, no. The main exceptions are the Prickly Pear Trail, which closes outright for hunting season, and Redden State Forest on weekdays, where hunting is permitted. Wearing blaze orange on any trail near huntable land is a sensible habit in September through February. The hunting seasons and trail safety guide has the specifics.
Are state park fees still charged in the fall?
Yes, through late November at most parks. The campground at Cape Henlopen runs through November 30. Vehicle entrance fees for day use follow a similar arc at other state parks, though exact cutoff dates vary by park and year. Check destateparks.com for current fee season dates. Redden, Prime Hook, and the rail-trails are free year-round.
