Cape Henlopen State Park
Where Delaware Bay meets the ocean — swimming beaches, a WWII fort you can climb, and a touch-tank nature center, all in one big Lewes park.
The Quick Version
- • A 5,450-acre beach park at the tip of the Delaware coast in Lewes — ocean and bay swimming beaches, a fishing pier, big dunes, and miles of bike trail.
- • The family extras that set it apart: the Fort Miles WWII bunkers and a climbable observation tower, plus the Seaside Nature Center's touch tank.
- • Per-vehicle entrance fee in season ($5 DE / $10 out-of-state); lifeguards Memorial Day–Labor Day.
- • About 1.5–2 hours from Wilmington; an easy full beach day, and you can bike the trail toward Rehoboth.

What to Expect
Cape Henlopen is a 5,450-acre park where Delaware Bay meets the Atlantic, just outside Lewes — and it's far more than a beach. There are two swimming beaches (lifeguards Memorial Day to Labor Day), a 24-hour fishing pier on the bay, tall dunes, and miles of paved trail you can bike toward Rehoboth.
What makes it a standout family day is the history and nature layered on top. During WWII the Army built Fort Miles here, and the park is dotted with bunkers and concrete observation towers — you can climb a restored tower for sweeping ocean views. The Seaside Nature Center has marine aquariums and a touch tank, plus hayrides, guided walks, and birding programs. The bay shallows are gentle for little kids, and in late spring horseshoe crabs cover the sand.
Set expectations: it's a big park — pick your mix (beach plus tower, or nature center plus a bike ride) rather than trying to do everything. The Point at the tip closes seasonally to protect nesting shorebirds, so check before heading out there.
Who It's Best For
Babies and toddlers love the calm bay beach, the touch tank, and the horseshoe crabs. Bigger kids get ocean swimming, climbing the WWII tower, exploring bunkers, and biking the trail. Genuinely an all-ages park.

What to Skip with Little Ones

The only charge is the standard Delaware State Parks per-vehicle entrance fee, in effect roughly March–November. Walk-in and bike-in are free.
Membership tip: A Delaware State Parks annual pass ($50 DE residents) covers the entrance fee here and at every state park — easy to justify for a beach summer.
Getting There
Parking
Large beach and trailhead lots; they fill on summer weekends.
Summer weekend lots fill by late morning — arrive early or come late afternoon.
Entrance
Enter off Cape Henlopen Drive from Lewes; pay the vehicle fee at the entrance booth in season.
Parent Logistics
The paved paths and the nature center are stroller-easy. The beach is soft sand and the tower has stairs, so a carrier and beach gear help.
Bathhouses at the swimming beaches and restrooms at the nature center.
Not confirmed — plan ahead.
Limited on the open beach — bring an umbrella or beach tent. The nature center and wooded trails are shaded.
Food & Snacks
Seasonal snack concessions at the beach and the fishing center. Otherwise bring your own.
Snack strategy: Pack a cooler for a beach day. Historic Lewes is minutes away for a real meal.
