The Bulb Region
The Bollenstreek is the bulb-growing district between Leiden and Haarlem, behind the dunes of the North Sea coast. Its towns include Lisse, Hillegom, Sassenheim, Voorhout, Noordwijkerhout and Noordwijk. In spring the flat farmland is divided into long strips of colour as tulips, hyacinths and daffodils come into flower, and the area is crossed by quiet, well-marked cycle paths. A bike is the best way to see it: you can stop wherever the view is good, and you avoid the traffic jams that build on spring weekends.
When to Go
Flowering follows a rough sequence. Crocuses and daffodils come first, from March. Hyacinths, which give the strongest scent, follow, and tulips usually peak around mid-April. The exact timing changes each year with the weather, and a warm or cold spell can move it by a week or two.
The window is short. Growers cultivate the bulbs, not the flowers, and the flower heads are removed once the bulbs have gained what they need, so by late April or early May many fields are green again. Check current bloom reports from the regional tourist office or Keukenhof before you fix your date.
Where to Start
The region is easy to reach by train. Leiden Centraal, Voorhout, Hillegom and Haarlem stations all give access to the fields, and you can rent a bike at or near the larger stations. During the Keukenhof season, bikes can also be hired in Lisse near the park. Booking ahead is wise on spring weekends, when rental fleets run out.
From Leiden, a ride north through Voorhout and Sassenheim to Lisse and on to Hillegom covers much of the core growing area. From Haarlem, the route south via Bennebroek to Hillegom and Lisse works equally well. Either can be turned into a loop or ended at another station on the Leiden to Haarlem line.
Using the Cycle Junction Network
The Netherlands has a nationwide network of numbered cycle junctions, called knooppunten. At each junction a sign shows the numbers of the next ones, so you can plan a route as a simple list of numbers and follow it without a map. Regional tourist offices and route planners publish suggested flower routes on this network, and it is easy to build your own on a planning website or app before you set off.
Distances are modest. A ride of 25 to 40 km, with stops, fills a relaxed day, and there are no hills. The main challenge is wind: open fields offer little shelter, and a headwind off the coast can make the return leg much slower than the outward one.
Etiquette in the Fields
The fields are working farms on private land. Stay on roads and paths, do not walk into the rows and do not pick flowers; trampling damages the crop, and the risk of spreading plant diseases is taken seriously. Many farms put up signs asking visitors to keep out, and some have dedicated spots or shops where you are welcome to stop and buy bulbs or flowers.
Pull right off the path to stop for photographs. On busy days, cyclists stopping suddenly in the middle of narrow paths cause accidents.
The Flower Parade
The Bloemencorso Bollenstreek, held in mid-April, is the region's biggest spring event. It began in 1947 and now sets off on a Friday evening from Noordwijk, passing Noordwijkerhout with a light show, before continuing the next day through Voorhout, Sassenheim, Lisse, Hillegom, Bennebroek and Heemstede to Haarlem. The floats are decorated with flowers from the region. On parade days roads along the route close and the area is very busy, so either plan your ride around the parade or avoid that weekend.
Practical Tips
- Bring a waterproof layer: April showers are common.
- Weekdays are much quieter than weekends.
- Keukenhof is a separate, ticketed park; you can combine it with a ride, but it needs at least half a day of its own.
- Use bike locks at every stop, and park in designated areas in towns.
- Carry water and snacks; cafes are spread out between the villages, and some fill up at lunchtime on sunny days.
- Give way to local riders and keep right on busy paths, as many people commute through the fields by bike.
- If you are not used to Dutch cycling, practise in a quiet street before heading out on a busy weekend.
