How Slow Travel Lowers the Footprint of a Spring Trip to Holland

Every spring, the bulb fields between Leiden and Haarlem turn into strips of red, yellow and violet visible from the air. Large numbers of visitors travel to see them.

A large share of visits takes place during the short spring bloom period, and visitors may rely on flights, cars, coaches and other forms of transport to reach the region.

The environmental pressure does not come from the flowers themselves, but from the transport, tourism activity and agricultural practices associated with the bulb industry and the visitor economy.

According to the European Environment Agency, transport accounted for about 31% of EU-27 greenhouse gas emissions in 2023, making it the largest-emitting sector. Road transport accounted for 72.9% of transport emissions that year. How people move remains the decisive variable in any trip’s footprint.

Slow travel offers a different structure for the same holiday. Fewer transfers, longer stays, lower-emission modes, and a schedule that spreads demand rather than concentrating it.

What Slow Travel Actually Means

Slow travel is often mistaken for a preference about pace. It is closer to a set of measurable decisions.

The core principle is fewer separate journeys. Each flight, transfer and road journey adds emissions, while combining destinations into a more continuous route can reduce the amount of transport required.

Mode selection matters enormously. EEA analysis shows that rail has the lowest greenhouse gas emissions among the main motorised passenger transport modes. Road transport remains the largest source of transport emissions, while aviation and maritime transport also contribute significantly to air pollution, including smoke pollution. The environmental performance of waterborne travel varies by vessel and operation.

The second principle is duration. Longer stays spread the fixed emissions of arrival across more days, lowering the daily footprint of the trip.

The third is dispersal. Visitors who stay in one place and use buses, bicycles or walking for local journeys can reduce transport emissions and traffic pressure compared with repeated car journeys.

Why a Spring Tulip River Cruise Fits the Slow Travel Model

European tourism remains heavily concentrated in a short summer window. Eurostat figures show EU residents spent 15.7% of their tourism nights in July and 16.5% in August during 2024, with the peak month running 3.7 times higher than the quietest month of the year.

Spring travel sits outside the main European summer peak. Spreading tourism demand across a longer season can reduce the environmental pressure associated with highly concentrated visitor flows.

River travel uses existing waterways across the Low Countries, but this does not automatically make a trip low-impact. Vessel efficiency, fuel use and the type of passenger vessel can all affect its environmental footprint.

One example is the set of Netherlands and Belgium seasonal bloom itineraries offered by Celebrity Cruises, which connect multiple destinations by water.

Connecting several destinations by water may reduce the need for some separate transfers and road journeys, but the vessel’s emissions and the rest of the journey still need to be considered.

The resulting footprint depends on the vessel’s emissions as well as the transport used to reach ports and travel between ports and other attractions.

A slow-travel approach should therefore assess the entire journey, including vessel emissions, access to ports and transport at each destination, rather than treating waterborne travel as environmentally preferable by default.

6 Ways Spring Visitors Can Reduce Their Environmental Impact

1. Travel overland where practical. Rail generally has a much lower greenhouse gas footprint than aviation and car travel, making it a strong option for reaching the Netherlands without a short-haul flight.
2. Stay longer in fewer places. A longer stay can spread the emissions associated with reaching a destination across more days and reduce the need for repeated journeys between places.
3. Use cycling infrastructure where practical. Cycling can replace some short car journeys and reduce transport emissions and traffic pressure around rural attractions.
4. Visit fields from designated paths only. Staying on marked routes helps prevent damage to crops and reduces disturbance to cultivated soil.
5. Support growers and producers that disclose environmentally responsible farming practices where possible, rather than assuming that a local purchase automatically has a lower environmental footprint.
6. Consider travelling outside the busiest part of the bloom season where conditions allow. Spreading visits across the season can reduce pressure on local infrastructure and the surrounding environment.

What Happens in the Fields Between the Photographs

Visitors see color. Growers see a demanding monoculture crop.

Flower bulbs are vulnerable to plant-virus infections, which can affect production and exports. Wageningen University & Research notes that flower-bulb exports can be badly affected by plant-virus infections and that reducing pesticide use is an active area of research.

Wageningen researchers note that more than nine million kilos of pesticides are sold in the Netherlands each year, mostly fungicides and herbicides, including roughly 700,000 kilos of glyphosate, with flower bulbs among the export crops that depend heavily on protection against plant viruses.

Researchers are investigating approaches such as resistant varieties, precision application and integrated pest management to reduce pesticide use.

Visitors have limited influence over cultivation practices, but they can support farms and tourism businesses that disclose efforts to reduce pesticide use and other environmental impacts.

Does Timing Matter as Much as Transport?

In many destinations, yes.

A Parliament study on overtourism found that the most common interventions used by destination management organizations involve spreading visitors across time and space, essentially prolonging the season and dispersing arrivals across more attractions.

High visitor concentration can place additional pressure on local infrastructure and natural resources. Water systems, waste collection and transport networks must handle demand that can rise sharply during busy periods.

Spring visitors to the bulb region are already travelling outside the main European summer peak. Within the spring season, though, visitor demand can still become concentrated around the short tulip-bloom period.

Shifting a trip away from the busiest dates can help spread visitor pressure across the season while leaving much of the experience unchanged.

Small Travel Choices Still Add Up

No single holiday decides anything. The aggregate of millions of similar decisions does.

Choosing a continuous route over multiple journeys, staying longer in one place, using rail where practical, carpooling when driving is necessary, and avoiding the busiest periods can reduce several sources of environmental pressure at once.

These choices do not require eliminating tourism. They focus on reducing transport emissions, spreading visitor pressure and limiting disturbance to the agricultural landscape.

The Dutch bulb season is brief, but its environmental footprint extends beyond the fields themselves. How visitors travel, when they arrive and how they behave around cultivated land can all affect the pressure placed on the region.
