Koekamp, Oostduinen, Meijendel and Kasteel Oud Wassenaar Loop

This is a long, mostly flat day-walk linking some of the most distinctive landscapes between The Hague and Wassenaar: formal city parks and ponds, coastal dune systems, and a stately country-estate setting. At around 31 km / 19.3 mi with roughly 0 m / 0 ft of climbing, it’s physically “easy” in terms of elevation, but it’s still a full-day outing because of the distance and the amount of time you’ll spend on mixed surfaces (paved promenades, compacted gravel, sandy dune paths).

Getting to the start (public transport + car)

Because the start is listed only as “near,” the most practical and common trailhead for this loop is by Koekamp Park, immediately beside Den Haag Centraal Station—a major, unmistakable landmark and the easiest place to arrive without a car.

• By train/tram/bus: Travel to Den Haag Centraal. From the station forecourt, you can walk straight into Koekamp in a couple of minutes. This is ideal for a point-to-point feel even though it’s a loop, because you can finish and immediately have food, restrooms, and onward connections.
• By car: Aim for parking around Den Haag Centraal / Malieveld (signed city parking garages are common here). City parking can be expensive and time-limited; if you’re driving, check restrictions before you leave the car for a full day.

If you’re using HiiKER for navigation, set your start point to Den Haag Centraal Station (Stationsplein, The Hague) or Koekamp / Malieveld—both are prominent and will anchor the route reliably.

What the route feels like underfoot

Expect a steady alternation of: - Urban park paths (smooth paving and wide gravel) - Estate lanes and cycleways (hard-packed gravel/asphalt) - Dune tracks (often sandy, sometimes soft and energy-sapping even when “flat”)

Even with negligible elevation gain, sand can be the real effort multiplier. If conditions are dry or windy, dune sections can feel slower than the distance suggests.

Segment-by-segment: landmarks, scenery, and pacing

Koekamp and the Haagse Bos edge (first ~3–6 km / 1.9–3.7 mi)
You begin in a classic Hague green corridor: lawns, mature trees, and ponds right beside the city’s transport hub. Koekamp and the adjacent green spaces form part of the historic parkland fabric around the city center. Early on, you’ll likely pass: - Ponds and waterfowl habitat (look for ducks, coots, geese, and herons) - Long, straight park avenues lined with tall trees—excellent for easy, fast walking

This opening is a good place to settle into a sustainable pace. If you’re trying to keep the day comfortable, aim for a “conversational” speed here and save energy for the sand later.

Oostduinen / dune transition (roughly ~6–14 km / 3.7–8.7 mi)
As you leave the more formal city greenery, the landscape starts to open and lighten: fewer tall trees, more scrub, and the first real dune character—wind-shaped vegetation, sandy shoulders, and a sense of moving toward the coast. The “Oostduinen” area is part of the broader coastal dune belt that protects the Netherlands’ shoreline and supports specialized habitats.

What to look out for: - Sandy patches that can appear suddenly on otherwise firm paths - Cyclists on shared routes—many Dutch paths are multi-use and fast-moving - Exposed wind: even on mild days, the dunes can feel cooler and more drying than the city

Wildlife and plants you may notice include small songbirds in scrub, rabbits, and hardy dune vegetation adapted to salt, wind, and shifting sand.

Meijendel: the big nature section (roughly ~14–24 km / 8.7–14.9 mi)

Meijendel is where the walk becomes most “wild” in feel, even though you’re never far from civilization. This dune landscape is ecologically important and also closely tied to Dutch water history: coastal dunes commonly function as natural water filtration and protection zones, and many dune areas are managed carefully for both nature and water supply.

Expect: - Rolling dune forms (visually undulating, but still minimal net elevation gain) - A mix of firm and soft footing—some tracks are compacted, others are loose sand - Open vistas across dune bowls and scrubby ridges

Practical planning notes for this section: - Time budgeting: This is where your pace may drop. If you normally walk 5 km/h (3.1 mph) on pavement, you might fall to 3.5–4.5 km/h (2.2–2.8 mph) in softer sand. - Sun and wind exposure: Bring a light wind layer even in fair weather; dunes can be breezy. - Water and snacks: Treat this as the “commitment” portion—carry enough to be comfortable until you’re back toward more built-up edges.

Kasteel Oud Wassenaar and estate atmosphere (roughly ~24–31 km / 14.9–19.3 mi)

The final third trends toward Wassenaar’s greener, more manicured character—estate lanes, tree-lined roads, and a calmer, shaded feel compared with the open dunes. Kasteel Oud Wassenaar (Castle Oud Wassenaar) is a notable historic landmark in the
