The Paddington Arm of the Grand Union Canal was constructed through the area and opened in 1801, and the canal now forms part of the town's eastern border with the adjacent town of Greenford. The town's fastest period of growth came during the mid-part of the 20th century when the population grew from 904 in 1921 to 26,000 in 1961. In 1926, Northolt Park Railway Station was opened, followed in 1935 by the construction of the A40 road. Northolt tube station followed in 1948.
To the south of the A40, a small area of farmland was leased to the neighbouring council from 1938 and called 'Royal Borough of Kensington Playing Fields'. The adjacent road was renamed Kensington Road to mark this association. During the Second World War, it was also the site of the Smith's Farm PoW camp, which held Italian prisoners of war. The lease with the Royal Borough of Kensington continued until 1997, when Ealing Council decided to use the land to create a new park as part of the 110 hectares of continual green space known as 'Northolt and Greenford Countryside Park'.
The new park was opened in 2008 and named 'Northala Fields' in a nod to the area's historic name and was given the Green Flag Award the following year. It consists of 10 artificial ponds laid out in a geometric pattern; one for boating, six for fishing and the remaining three for wildlife. The park also features 2 children's playgrounds, playing fields, wildflower meadows, marshland, a cafe, and the four striking conical mounds that dominate the park's northern border, separating it from the A40 Western Avenue.
The park cost £5.5 million to construct. However, it was created at absolutely no cost to the taxpayer by using a unique method of funding. Cleverly, the funds were raised by allowing 1.5 million cubic metres of rubble from the demolition of the old Wembley Stadium to be deposited here. The material was used to construct the four on-site mounds. Using this method of disposing of the waste materials saved 160,000 lorry journeys, each of up to 200 miles to outlying tips. The mounds also provide a sound barrier from the constant rumble of traffic from the adjacent A40.
Each of the mounds has been created with varying soil conditions which support four distinct habitats. The tallest is 26 metres high (84ft) and boasts panoramic views in all directions. Fittingly, this also includes a view of the new Wembley Stadium arch to the north-east. The park and mounds were featured in an episode of Taskmaster (S4, Ep 5) where the contestants were tasked to take three exercise balls to the top of the highest mound. The mounds and other ornamental parts of the park are considered to be the largest example of 'land art' in Europe and have won a number of design awards.
In 2014 the park became home to a free, weekly, timed, 5-kilometre event called Northala Fields parkrun, which I first visited on the 5th of July 2014 to take part in event number 3. This expanded write-up is from my second visit which was just over 12 years later, on 22 August 2026 at event number 564. The parkrun is a fully inclusive event and is perfectly suited to all abilities including those who wish to walk the course. Like all parkruns, it is organised and staged every week by volunteers.
When visiting this parkrun, there are a few travel options. The closest National Rail station is Greenford which is 1.4 miles away from the park. Please note that it is on the Greenford branch line and is only served by Great Western Railway (GWR) shuttle service from West Ealing. West Ealing has further connections to the rest of the GWR rail network and the Elizabeth Line. The best option for train travel would be to use the Central Line and alight at Northolt tube station which is 800 metres away from the park. The Central Line runs all the way from Epping, in Essex, through central London and out to West Ruislip. Interchange to the Central Line is possible at Greenford station. If using buses, the E10 stops outside the eastern side of the park on Kensington Road and the 90, 120, 140 and 282 buses all stop on the western side of the park, near the Target Roundabout. There are additional buses, the E7 and E9, which stop further away, to the south.
Travel by vehicle is possible and as the park is adjacent to the A40, the road links are good. If using the A40 you need to leave at the Target Roundabout which is marked on road signs as the A312 exit. The exact route you take from here is dictated by your intended parking spot. The official parking areas are the two on-site car parks 'Northala Fields Car Park 1' and 'Northala Fields Car Park 2'. If using either of these, the route after leaving the A40 feels wrong because you initially head away from the park. I would advise looking at a map before travelling so you understand the road layout.
The official car parks used to be free-of-charge, but sadly this is no longer the case. Payment is made by using the paybyphone website or app, or by phoning the number on the information board. There are no payment machines. I would advise that you download and set up this app before travelling. The exact cost per hour is determined by the vehicle's CO2 emissions. As an example any vehicle with CO2 emissions of less than 100g per km (electric and very small ICE cars) would fall into the lowest band are charged at £1.10 per hour, while larger family cars and sports cars would end up in the higher bands and may pay £1.94 per hour. Certain diesel vehicles have to pay £2.20 per hour. The pricing information is correct as of August 2026.
It is possible to avoid the parking charges by using the free on-street parking which is available on most of the residential roads on all sides of the park. Spaces are at a premium so it's best to arrive early. On this visit, I used a side street near Lilliput Avenue (west of the park, and very packed with local resident's cars already), but other options can be found on the roads around Bengarth Road (also west), Dolphin Road (south) or to the east of Kensington Avenue. The main advice I can give is to double check upon arrival in case the council have made any changes and don't park anywhere silly, like in front of someone's driveway or on a double yellow line. Lastly, if cycling, there are loads of bicycle racks inside the park near the cafe.
If overnight accommodation is required, there are an abundance of hotels within a reasonable distance. The closest and by far the most convenient is the Travelodge London Northolt which is located right next to Northolt tube station, so is easily within walking distance of the park. The closest Premier Inns are London Hayes, Heathrow (North A4020) which is 2.6 miles away and London Greenford which is 4.4 miles away. There are so many more options, so if you have a favourite chain or if you prefer an independent there will definitely be something for you.
The toilet situation seems to have conflicting information. There is a toilet located in the cafe building, but it is noted on the parkrun's website as being 'currently unavailable'. I have heard varying reports some of which say that the toilets are open from 9am (which aligns with the cafe opening time), and others where it is open pre-parkrun. If it is open before parkrun, it is very likely that a queue will form, so get in the queue earlier rather than later. As a more reliable back-up option there is a toilet in the nearby McDonalds which is next to the Target Roundabout - it is very close and can easily be reached on foot via the subway from the park's north-west entrance. As an interesting side note, the McDonalds occupies the building which was formerly 'The Target' public house and this is where the famous roundabout gets its name.
The parkrun meeting point is on the path in between the mounds and the cafe and the briefing takes place at the large intersection just next to the cafe and the mounds. An interesting quirk at the briefing here is that anyone that has reached a parkrun milestone is called out of the crowd and is elevated to the milestone bench where they have a quick photo and receive a round of applause.
The 5 kilometre course is essentially one lap, but it has elements of a lollipop and there are a few sections which are covered twice in different directions. The surfaces underfoot contain a mixture of tarmac, gravel, stones and a sandy surface so I'd say road shoes are probably fine all year round, but some may prefer a very light trail-style shoe when conditions are unfavourable. Participants with a wheelchair, buggy or a dog are welcome in line with the standard parkrun guidance. I would point out that the stony sections may present a problem for some wheelchair users. My GPS data recorded 11 metres of elevation change, and overall this course can be classed as flat.
The start is on the main central path and the course initially heads towards the northeast and past the meeting area where a full anti-clockwise loop of the three easternmost mounds is completed. The path around the back of the mounds is quite stony but has some lovely meandering curves to it. Returning to the main central path the course heads away from the mounds and enters a separate area called Medlar Fields and this leads into a completely different park called Rectory Park (both are also part of the larger Northolt and Greenford Countryside Park). This is a fairly large open space with a focus on sports, mostly football and cricket, but there is also a skatepark and playground here. The Rectory Park section is a fairly simple clockwise loop of the fields, which cuts into the centre when reaching the 4G football pitches and finishes with a brief section through a small patch of woodland. The Rectory Park paths are slightly narrower and the surface is largely a dusty, sandy, gravelly path.
With the loop complete, the route passes back through Medlar Fields and onto the main central path. Once back at the mounds there is a clockwise loop of all four mounds to negotiate before reaching the finish which is located on the main path in between the mounds and the cafe. Barcode scanning takes place shortly after crossing the line. Overall the course is well marked with a combination of directional arrow signage and marshals positioned at strategic points around the course.
I recorded the route with my Garmin and the GPS data can be viewed via my Strava account (you may need to sign in to view it). I also used the data to create a Relive course fly-by video which can be watched on YouTube. The current course is slightly different to the one that was in use when I first visited, and there have been other variations over the years. The results were processed shortly after the event and there were 368 participants at event 564. This was close to the average number of attendees which tends to be around 350. In the colder conditions this may fall to around 250. The highest attendances at this event were recorded just before the pandemic where over 500 participants were becoming the norm. The overall attendance record is 594 and this was recorded on Christmas Day 2019.
As far as possible cancellations are concerned the main reason for cancellation at this venue is the weather or dangerous underfoot conditions such as snow and ice. There have also been cancellations for lack of volunteers and when the course has been obstructed by maintenance works. I haven't found any instances of cancellations for other events, but if anything comes to light I will add it here.
Once the parkrun is over, the natural place to grab some refreshments is the San Remo Cafe, right next to the finish line. It is fairly small inside so not a huge amount of internal seating, but you may find a seat or bench outside, again not loads. They have the usual kinds of coffee shop drinks and snacks, plus they also do full breakfasts (traditional and vegetarian), baps and various items on toast. If that doesn't take your fancy, the next closest option would be the McDonalds at the Target Roundabout.
Some parkrunners also take part in the four peaks challenge which is simply getting to the top of all four mounds in succession. As I sat relaxing in the sun I watched plenty of people doing this. Finally, if you have kids with you they will most-likely love the playground outside the cafe, so don't expect a quick getaway!
Also, I thought it was worth mentioning this venue's link to another parkrun. We know that the rubble from the old Wembley Stadium is here, but the construction material was originally quarried from the ground over at Rickmansworth Aquadrome (creating the holes that are now the lakes) which is now home to Rickmansworth parkrun.
Overall, this is a brilliant parkrun venue with a smashing bunch of locals who really made us feel welcome. It is of course part of the Londone set of parkruns and as the name contains the word 'north' it is also part of the Compass Challenge, so these elements naturally keep the tourists coming! Lastly, a huge thank you goes to all of the volunteers.
