Step-by-Step Guide

Walking the Brentford Lock is not a single path but a curated journey that connects multiple public rights of way, towpaths, and pedestrian bridges. The route spans approximately 1.8 miles (2.9 kilometers) and typically takes 3550 minutes at a moderate pace, depending on stops and conditions. Below is a detailed, sequential breakdown of each segment.

Start Point: Brentford High Street to the Lock Gate

Your journey begins at the bustling Brentford High Street, near the intersection with Kew Road (A4). Look for the signposted footpath leading south toward the River Thames, just past the Brentford Library and opposite the historic Griffin Pub. Follow the narrow pavement past the Brentford Community Stadium (home of Brentford FC) until you reach a set of stairs descending to the riverside path.

Once on the riverside, youll enter the Thames Path National Trail. This is a well-maintained, flat gravel and tarmac path that runs parallel to the river. Stay on the left-hand side (north bank) as you walk westward. The path is clearly marked with the official Thames Path acorn symbol. As you proceed, youll pass several moored narrowboats, seasonal flower beds maintained by local volunteers, and benches offering views of the water.

After approximately 600 meters, youll see the distinctive brick and iron structure of Brentford Lock ahead. The lock chamber is flanked by two large lock gatesone upstream (eastern) and one downstream (western). Do not attempt to cross the lock gates themselves; they are operational machinery and are strictly off-limits to pedestrians during active lock operations.

Approaching the Lock Chamber

As you near the lock, the path splits slightly. Take the left fork, which leads along the northern bank toward the lock keepers cottage and the footbridge. This section is shaded by mature willow trees and often frequented by kingfishers, herons, and other waterfowl. Look for interpretive panels mounted on wooden posts that detail the locks history, construction date (1815), and its role in the Industrial Revolution.

At this point, youll notice a small, gated pedestrian bridge crossing the locks upper chamber. This is the official crossing point. The bridge is made of cast iron with wooden slats and is supported by stone piers. It is accessible 24/7, but be cautious during high tide or after heavy rain, as the surface can become slippery.

Crossing the Lock Bridge

To cross safely:

• Check for warning lights or signs indicating active lock operation. If red lights are flashing or a horn is sounding, wait until the sequence completes. Lock cycles typically last 1015 minutes and occur hourly during daylight.
• Walk briskly but steadily. Avoid stopping in the middle of the bridge.
• Keep children and pets close. The drop to the water on either side is approximately 2 meters.
• Do not lean on railings or attempt to touch the lock mechanisms.

Once across, youre on the western side of the lock, where the River Thames meets the Grand Union Canal. This junction is historically significantit was once a key transshipment point for coal, grain, and manufactured goods between London and the Midlands.

Continuing to the Grand Union Canal Towpath

Immediately after crossing the bridge, the path continues westward along the northern edge of the canal. This section is known as the Grand Union Canal Towpath and is part of the National Cycle Network Route 4. The surface transitions to compacted earth and gravel, so wear sturdy footwear.

As you walk, youll pass:

• The former Brentford Gas Works, now redeveloped into residential units with preserved chimney stacks.
• A series of mooring buoys and private narrowboats, many of which are lived-in year-round.
• A public art installation titled Echoes of the Thames, featuring bronze plaques with poems by local schoolchildren.

After another 400 meters, youll reach a junction with a footbridge over the canal, leading to the Brentford A306 (Isleworth Road). This is a natural endpoint for many walkers, but if you wish to continue, you can follow the canal path further toward Hounslow or return the way you came.

Return Route Options

For a loop walk, consider returning via the Brentford Riverside Walk, which runs parallel to the canal on the southern side. This route is less traveled and offers more wildlife spotting opportunities. Access is via a pedestrian crossing near the Brentford Ferry terminal. Alternatively, retrace your steps along the Thames Path and return to High Street via the Kew Road overpass.

Best Practices

Walking the Brentford Lock is a low-impact activity, but responsible behavior ensures the longevity of the environment and the safety of all users. Below are essential best practices to follow.

Respect Operational Boundaries

Locks are working infrastructure. Even if the gates appear open or idle, never enter the lock chamber, climb on machinery, or attempt to operate levers. The Environment Agency and Thames Water maintain strict safety protocols. Violating these boundaries risks serious injury and legal penalties.

Leave No Trace

Carry out everything you bring in. Plastic bottles, food wrappers, and even biodegradable items like fruit peels can disrupt aquatic ecosystems. The Thames is a designated Site of Special Scientific Interest (SSSI) in this stretch. Use the bins provided at the lock keepers cottage or the nearby Kew Bridge station.

Wildlife Awareness

Brentford Lock is a haven for protected species, including the Eurasian otter, water vole, and kingfisher. Avoid sudden movements, loud noises, or flash photography near the waters edge. Keep dogs on a short lead (maximum 2 meters) and clean up after them immediately. Many birds nest in reed beds between March and Auguststay on marked paths during breeding season.

Weather and Footwear Considerations

The path can become muddy after rain, especially near the canal junction. Wear waterproof, non-slip footwear with good ankle support. In winter, ice can form on the bridgeuse handrails and avoid shortcuts over frozen water. Always check the Met Office forecast before setting out.

Accessibility and Inclusivity

The Thames Path is mostly flat and wheelchair-accessible, though the lock bridge has steps and narrow railings. For those with mobility impairments, the nearest accessible alternative route is via the A306 footbridge and the canal towpath west of the lock, which has gentler gradients. Contact the London Borough of Hounslows Accessible Routes team for real-time updates on path conditions.

Group Walks and Events

If organizing a group walk (e.g., school trip, walking club), notify the Environment Agencys Thames Waterways team in advance. Large groups can disrupt lock operations and disturb wildlife. Limit group size to 10 or fewer, and assign a designated leader to manage pacing and safety.

Photography and Filming

Personal photography is encouraged, but commercial filming requires a permit from the Canal & River Trust. Avoid using drones within 50 meters of the lock or canalthey are prohibited due to safety and noise regulations affecting wildlife.

Real Examples

Real-world experiences illustrate how the walk functions in practice and reveal insights not found in guidebooks.

Example 1: The Commuters Morning Walk

Emma, a 34-year-old data analyst, walks the Brentford Lock route every weekday morning to clear her mind before work. She leaves her home in Kew at 7:15 a.m., takes the Thames Path, crosses the lock bridge by 7:40 a.m., and continues to the canal towpath before catching the 8:05 a.m. train from Brentford Station.

Ive seen the lock go through five full cycles in one weeksometimes with a barge full of timber, other times with a family on a narrowboat holiday. Ive watched a kingfisher dive for fish right under the bridge. Its my daily dose of calm.

Emma uses the Thames Path App to check lock status. If the lock is scheduled to open during her walk, she waits on the bench near the lock keepers cottage and reads a chapter from her book.

Example 2: The History Students Research Walk

Daniel, a postgraduate student at UCL, walked the route over three weekends to document changes in the locks architecture. He photographed the original 1815 ironwork, compared it with 1930s restoration plates in the London Metropolitan Archives, and interviewed a retired lock keeper.

The locks original paddle gear is still in place beneath the modern hydraulic system. Most people dont realize its a hybrid of Georgian engineering and 20th-century upgrades. The walk isnt just a pathits a living museum.

Daniels research led to a published paper in the Journal of Thames Heritage Studies and a local exhibition at Brentford Library.

Example 3: The Family Adventure

The Patel familyparents and two children aged 7 and 10visited Brentford Lock on a Bank Holiday Monday. They brought sandwiches, binoculars, and a wildlife checklist from the Canal & River Trust.

We saw a heron catch a fish! My daughter thought the lock was a giant water slide, said Mr. Patel. We waited for the lock to open, and when the boat came through, the kids screamed with joy. We didnt realize how loud the water sounds.

They used the free printed map from Brentford Library and stopped at the picnic tables near the ferry terminal. We didnt buy anything. Just enjoyed the space. It felt like wed discovered a secret.

Example 4: The Solo Photographer

Lucas, a freelance photographer, spent a week capturing the lock at different times of day. His most famous image, Golden Hour at Brentford Lock, shows the setting sun reflecting off the water as a narrowboat passes through the gates, with the silhouette of the lock keepers cottage in the background.

I came at 5:30 a.m. for the mist, 11 a.m. for the light on the ironwork, and 7:45 p.m. for the sunset. Each time, the mood changed completely. The lock isnt staticit breathes.

His work was featured in Country Walking Magazine and helped boost local tourism interest.
