Yes, there are official canal swimming events in Amsterdam. The most well-known is the Amsterdam City Swim, an annual charity event that takes place each September and draws thousands of participants into the city’s historic waterways. Beyond that, a small number of other organised open-water events occasionally use the canals. Below, the most common questions about swimming in the canals Amsterdam visitors and residents ask are answered directly.
Which official canal swimming events take place in Amsterdam?
The Amsterdam City Swim is the main official canal swimming event in Amsterdam. Held every September, it is a charity swim covering roughly two kilometres through the city’s canals, with proceeds going to ALS research. It regularly attracts several thousand swimmers and has become one of the most recognisable open-water events in the Netherlands.
Outside of the Amsterdam City Swim, a handful of smaller open-water and triathlon events occasionally route participants through or alongside the canals, though these vary from year to year. There is no permanent calendar of regular canal swimming events beyond the September charity swim. If you are planning around a specific event, it is worth checking the Amsterdam City Swim website directly each year, as dates and registration windows shift.
Is it legal to swim in Amsterdam’s canals outside of events?
Swimming in Amsterdam’s canals outside of officially sanctioned events is technically not permitted. The municipality does not designate the inner-city canals as public swimming areas, and doing so carries practical and safety risks that make the prohibition sensible rather than arbitrary.
That said, enforcement is inconsistent, and on hot summer days you will see people jumping in near the Amstel or along quieter stretches of water. The city has historically tolerated this to a degree, but it has also stepped up water safety messaging in recent years as canal swimming has grown in popularity. The bottom line: outside of an organised event, you are swimming at your own risk in more ways than one.
Are Amsterdam’s canals actually safe to swim in?
Amsterdam’s canals are significantly cleaner than they were several decades ago, but they are not consistently safe for recreational swimming. Water quality varies by location and season, and the canals carry real hazards, including boat traffic, poor visibility, cold temperatures, and unpredictable currents near locks and sluices.
The city has invested in improving water quality since the 1990s, and monitoring data shows measurable progress. However, after heavy rainfall the canal water can become contaminated by overflow from the sewer system, making conditions genuinely unhealthy. Organised events like the Amsterdam City Swim time their routes and dates carefully, with water quality tested in advance. That is one of the reasons these events exist in a structured form rather than as a free-for-all. If you are considering swimming outside of an event, the Amstel and some outer waterways tend to have better water quality than the densely connected inner-city canal ring.
How do you sign up for the Amsterdam City Swim?
Registration for the Amsterdam City Swim opens online through the event’s official website, typically several months before the September swim date. Spots fill quickly, so signing up early in the year is strongly advised. Participants choose a distance, pay a registration fee, and commit to raising a minimum amount for ALS research.
The process is straightforward:
- Visit the official Amsterdam City Swim website and find the registration page for the current year.
- Select your preferred distance and starting wave.
- Complete your personal details and pay the entry fee.
- Set up your fundraising page and begin collecting donations toward your minimum target.
- Receive your swimmer pack and event-day instructions closer to September.
No elite swimming ability is required. The event is open to recreational swimmers, and many participants complete it in wetsuits. The atmosphere is festive rather than competitive, which is part of what makes it one of Amsterdam’s more charming annual traditions.

Frequently Asked Questions
What should I wear and bring if I'm participating in the Amsterdam City Swim for the first time?
A wetsuit is highly recommended, as canal water in September can be cold enough to affect your performance and comfort over a two-kilometre swim. Most participants also wear goggles and a brightly coloured swim cap, which the event typically provides for visibility and safety purposes. Beyond your swim gear, bring a change of warm clothes and a towel for after the swim, and arrange for someone to look after your belongings while you’re in the water.
Are there any safer alternatives to canal swimming in Amsterdam if I just want an outdoor swim?
Yes — if you want to swim outdoors in Amsterdam without the risks associated with the inner-city canals, the city has several designated outdoor swimming spots worth knowing about. Sloterplas and Amsterdamse Bos both offer monitored open-air swimming areas with better water quality standards than the canal ring. These are the spots locals actually use for a proper summer swim rather than a spontaneous canal dip.
What happens if I miss the registration window for the Amsterdam City Swim?
If registration closes before you manage to sign up, your best option is to check the official website regularly for any waitlist or late-entry options, as these occasionally open up closer to the event date. You can also follow the Amsterdam City Swim on social media, where last-minute spots or cancellation openings are sometimes announced. In the meantime, registering your interest early for the following year’s event is the most reliable way to avoid missing out again.
