De Hooiberg, De Groene Jonker, Fort Sch sl and Aalsmeer Loop

This is a long, very flat, big-sky loop through the Dutch “polder” landscape—canals, dikes, pasture, reedbeds, and lakes—linking a handful of standout landmarks: De Hooiberg (a small hill/park feature in an otherwise level region), the wetland reserve De Groene Jonker near Vinkeveense Plassen, the historic defense works around Fort Schiphol, and the water-and-aviation edge of Aalsmeer. At roughly 70 km / 43.5 miles with about 0 m / 0 ft of climbing, the challenge is less about elevation and more about time on feet, wind exposure, and staying dry/comfortable on hard, flat surfaces.

Getting to the start (public transport + car)

Because your “Hike head: near …” field is incomplete and no coordinates were provided, the most practical assumption for a loop with these waypoints is a start near Hoofddorp Station (Stationsplein, 2132 TZ Hoofddorp, Netherlands) or Schiphol Airport rail station (Schiphol Plaza, 1118 AX Schiphol, Netherlands)—both are major transit hubs close to Fort Schiphol and make logistics easy.

• By train (recommended):
  • Hoofddorp Station is served by frequent NS trains from Amsterdam, Leiden, Haarlem, and Schiphol.
  • Schiphol Airport Station is one of the Netherlands’ best-connected rail nodes; you can step off a train and be on the route quickly.
• By bus:
  • Regional buses connect Hoofddorp/Schiphol with Aalsmeer, Amstelveen, and smaller villages along the ring of polders.
• By car:
  • Aim for parking near Hoofddorp Station (paid garages nearby) or designated lots around Fort Schiphol / Haarlemmermeer recreation areas. In this region, parking rules can be strict—use posted signage and avoid blocking farm access roads.

If you share a lon/lat for the intended trailhead, I can pin it to the nearest address/landmark precisely and adjust the route narrative to match.

What to expect underfoot and overhead - Surface: Mostly paved cycle paths, compacted dike tops, and farm access lanes. Expect long straight sections. - Exposure: Very open terrain—wind is often the biggest “elevation substitute.” A calm forecast can feel easy; a headwind can turn the day into a grind. - Water management: You’re never far from water (canals, lakes), but potable taps aren’t guaranteed. Plan refills around towns (Aalsmeer/Hoofddorp/Vinkeveen edges). - Navigation: The path network is dense with junctions; keep HiiKER handy for confirming which side of a canal/dike you’re meant to be on, especially where parallel cycleways run close together.

A workable breakdown (approximate) At 70 km / 43.5 miles, many hikers treat this as a full-day endurance walk (often 10–14 hours moving time depending on pace and stops). A practical way to plan is in 4 legs:

1) Hoofddorp/Schiphol area → Fort Schiphol: ~10–15 km / 6–9 miles, ~0 m / 0 ft
2) Fort Schiphol → Aalsmeer: ~15–20 km / 9–12 miles, ~0 m / 0 ft
3) Aalsmeer → De Groene Jonker (Vinkeveen area): ~20–25 km / 12–16 miles, ~0 m / 0 ft
4) De Groene Jonker → De Hooiberg → back toward Hoofddorp/Schiphol: ~15–20 km / 9–12 miles, ~0 m / 0 ft

Exact distances will vary depending on which dikes and crossings you choose.

Landmarks, landscape, and history along the way

Fort Schiphol and the defense landscape

Fort Schiphol sits in the wider story of Dutch water-and-fortification engineering: low-lying land, controlled flooding, and strategic lines of defense built to protect key approaches. Even when you’re just walking a quiet path beside a canal, you’re moving through a landscape that was deliberately engineered—drainage, pumping, and water control are the reason this route can be so flat and so walkable.

What to look for: - Earthworks and moats around fort areas (often subtle from a distance). - Straight canals and ditches laid out with surveying precision—this is “designed nature,” not wilderness. - Aircraft noise and flight paths near Schiphol: it’s part of the modern identity of the region and can be surprisingly loud at times.

Practical note: paths around fort sites can include narrow bridges, gates, and occasional short detours where access is restricted—double-check HiiKER when you see fencing or “private” signage.

Aalsmeer: water, polders, and working landscapes

Aalsmeer is closely tied to water and horticulture. As you approach, you’ll notice a shift from open pasture to more built-up edges, canals with heavier boat traffic in season, and a stronger “working town” feel.

What to look for: - Canal-side neighborhoods and small harbors—watch for fast cyclists and service vehicles on shared paths. - Long, narrow fields separated by ditches: classic polder geometry. - Birdlife increases near reedier margins and quieter waterways.
