Wild Swimming in Hertfordshire

Hertfordshire, with its picturesque countryside, tranquil rivers, and charming lakes, offers a haven for outdoor enthusiasts and wild swimmers alike. Tucked away from the hustle and bustle of London, this county provides plenty of opportunities to experience the joys of wild swimming in unspoiled natural settings. Whether you’re a seasoned swimmer or someone seeking to dip your toes into the world of wild swimming, Hertfordshire has something to offer.

What is Wild Swimming?

Wild swimming refers to swimming in natural waters such as rivers, lakes, and seas, rather than in man-made pools. It has seen a surge in popularity in recent years, particularly as people rediscover the mental and physical health benefits of connecting with nature. Immersing yourself in cool, fresh waters not only invigorates the body but also reduces stress, improves circulation, and boosts mood.

Hertfordshire’s rolling countryside is crisscrossed by rivers and dotted with serene lakes, making it an ideal location for this activity. With a little preparation and an adventurous spirit, wild swimming in Hertfordshire can be a rewarding experience.

Top Wild Swimming Spots in Hertfordshire

River Lea

The River Lea, flowing gently through the heart of Hertfordshire, is one of the county’s best-loved waterways for wild swimming. Stretching from Luton down to the River Thames in London, the Lea offers several scenic spots for a refreshing dip. One of the most popular swimming locations is near Ware, where the river widens and slows, creating calm conditions perfect for swimmers.

Why Swim Here? The River Lea is accessible, family-friendly, and surrounded by lush greenery. The riverside paths also make it a great spot for a post-swim walk.
Tips: Watch out for boat traffic in busier stretches and check the water quality after heavy rainfall to ensure it’s safe for swimming.

Grand Union Canal (Tring Reservoirs)

Though canals are not traditionally associated with wild swimming, the Grand Union Canal near Tring Reservoirs provides a unique and tranquil experience. This area includes four large reservoirs (Marsworth, Startops End, Tringford, and Wilstone), which feed water into the canal system and are popular with swimmers seeking quiet waters surrounded by wildlife.

Why Swim Here? The reservoirs boast stunning views and are home to various bird species, making it a haven for nature lovers.
Tips: Stick to designated areas where swimming is permitted, as some sections are reserved for fishing and boating.

River Stort

The River Stort, which flows through the eastern part of Hertfordshire, is another delightful destination for wild swimming. Near Bishop’s Stortford, the river meanders through serene countryside, offering crystal-clear water in spots ideal for a leisurely swim.

Why Swim Here? The River Stort offers a sense of remoteness despite being close to towns, giving swimmers a chance to escape into nature.
Tips: Enter the water cautiously, as riverbanks can be slippery, and avoid areas with strong currents.

Stanborough Lakes

Located in Welwyn Garden City, Stanborough Lakes is a well-maintained and popular spot for various water activities, including wild swimming. The two lakes—one dedicated to boating and the other for angling—provide ample space for open-water swimming.

Why Swim Here? While technically not “wild” in the strictest sense, Stanborough Lakes offers the perfect blend of safety and natural beauty, making it an excellent choice for beginners.
Tips: Check if open-water swimming sessions are running, as these ensure the area is supervised by lifeguards.

Rye Meads Nature Reserve

Situated on the edge of the River Lea, Rye Meads Nature Reserve is a peaceful spot for those seeking a secluded swim. The waters here are pristine, and the reserve itself is a haven for birdwatchers and wildlife enthusiasts.

Why Swim Here? Rye Meads is perfect for a serene swim surrounded by nature, far from the crowds.
Tips: As this is a nature reserve, respect the environment and avoid disturbing the local wildlife.

Benefits of Wild Swimming

Wild swimming is more than just a recreational activity—it offers a plethora of benefits for both body and mind.

Physical Health: The cold water improves circulation, strengthens the immune system, and provides a low-impact workout for the entire body.
Mental Well-being: Immersion in natural waters has been shown to reduce stress, combat depression, and improve overall mood. The combination of exercise and connection with nature creates a powerful antidote to modern life’s pressures.
Social Connection: Many wild swimming spots in Hertfordshire have vibrant communities of swimmers who meet regularly. Joining these groups can provide both safety and companionship.
Environmental Awareness: Spending time in natural water bodies fosters a greater appreciation for local ecosystems, inspiring efforts to protect and conserve these precious habitats.

Safety Tips for Wild Swimming

While wild swimming is invigorating, safety should always be your priority. Here are some essential tips:

Check Water Quality: Ensure the water is clean and safe for swimming. Avoid areas that may be contaminated or affected by agricultural runoff.
Enter Slowly: Give your body time to adjust to the cold water to prevent sudden shocks.
Swim with a Buddy: Never swim alone, especially in remote locations. Having someone nearby ensures help is at hand in case of an emergency.
Use a Tow Float: A brightly coloured tow float improves your visibility to boats and other swimmers while providing some buoyancy support if needed.
Avoid Strong Currents: Stick to calm waters and avoid areas with weirs, locks, or fast-flowing currents.
Respect Wildlife: Be mindful of the flora and fauna, and avoid disturbing nesting birds or aquatic life.

Wild Swimming Etiquette

Being considerate and responsible ensures that wild swimming remains a sustainable activity:

Leave No Trace: Take all litter home and avoid using chemical-based products (like sunscreen or insect repellent) that can harm aquatic ecosystems.
Respect Landowners: Some swimming spots may be on private property, so always seek permission before entering.
Be Quiet: Keep noise to a minimum to maintain the tranquility of the area and avoid scaring wildlife.

What to Bring

For a safe and enjoyable wild swimming experience, pack the following essentials:

A sturdy swimsuit or wetsuit (especially in colder months)
A towel and warm clothes for after your swim
Water shoes to protect your feet from sharp rocks or slippery surfaces
A dry bag to keep valuables safe and dry
Snacks and a flask of hot tea to warm up post-swim
