Where is the source of the River Thames?

Now that would be telling... only kidding. Thames Head is located in a field near the village of Kemble in Gloucestershire. The springs are seasonal and you have the best chance of seeing them on a wet day or after a big downpour. The location can change slightly depending on water levels but trying to find them is half the fun, right?

Is the River Thames clean?

Believe it or not, the River Thames is considered one of the cleanest city rivers in the world. The murky colour of the water might make you think otherwise, but the brown colour is because it’s a muddy river with a silt riverbank. The Thames was once declared biologically dead, but after changes to London’s sewage system and big cleanup efforts, it’s thriving once again with many wildlife species returning to the waters.

What animals live in the River Thames?

There are a surprising number of animals that live in the Thames. Along with over 125 species of fish including eel, trout and sole, you might also see porpoises, dolphins and seals. This hasn’t always been the case. It was only after extensive river cleanup and wildlife conservation projects that these species started to return and thrive. Above the water you’ll find mute swans, grey herons, kingfishers and coots – and of course the iconic mallard, AKA “the duck”.

Which towns and cities does the River Thames flow through?

The River Thames runs for 235 miles (354 kilometres) from Kemble in Gloucestershire to the North Sea in Kent. The major towns and cities it passes through include Oxford, Reading, Maidenhead, Windsor, Slough, Windsor and London.

Can I swim in the River Thames?

The Thames is a popular wild swimming spot. The swimming conditions and environment generally get nicer the further west you go. Like with any wild swimming (or swimming in general) it’s important to be aware of the risks and hazards, know your limits and follow the latest safety advice. The Port of London Authority (PLA) does not recommend swimming in the tidal Thames unless you are an experienced open-water swimmer due to powerful tides and undercurrents. If you want to swim in the tidal Thames you need to register for a permit.

River Thames highlights

Lake at Neigh Bridge Country Park, The Cotswolds, Gloucestershire, England, United Kingdom

Go wild swimming

        You won’t find any plastic slides and chlorine smells around here. Spanning a mighty 40 square miles and surrounded by natural beauty, the Cotswold Water Park is the perfect place to recharge the batteries. Take a cool dip (trust us, there’s no better way to start your day!), glide across the water on a paddleboard, go wakeboarding or chill out on a lakeside beach with a good book.

Boating In Punts On River Cherwell In Oxford, England, on a summers day

Try your luck at punting

        It wouldn’t be right to pass through Oxford without having a go at punting. Hitting the river on a flat-bottom wooden boat (AKA a 'punt') has been a favourite pastime in Oxford for hundreds of years. You can do a guided tour past the city’s most iconic spots or brave it in your very own boat to explore at your own pace. There’s plenty of pubs dotted along the riverbank to wet the whistle. From punt to pub – now that sounds like a great afternoon.

English country house, in Bampton, Oxfordshire, on a sunny day

Soak up the old-world charm of Bampton

        Could this old medieval town be any more delightful? Bampton oozes old-world charm with centuries-old buildings, quaint village shops and heaps of green space to sit and watch life go by. You might even recognise it from Downton Abbey – it’s where much of the hit series was filmed and it’s easy to imagine you’ve stepped back to the 1900s as you walk around. Hop on some wheels for a pleasant riverside cycle, explore the village on foot or sip your way through local tea rooms and pubs.

Go stand-up paddleboarding

        Fancy seeing the Thames from a different perspective? What better way than hopping aboard a stand-up paddleboard. Float from Eyndsham all the way to Oxford while you soak up the quintessential English scenery. You might even get a few friendly waves from passersby – just make sure you're steady if you wave back, unless you fancy a dip! Paddleboarding can work up quite an appetite, but there are loads of pubs dotted along the banks to grab some hearty grub and refuel.

Long walk to Windsor castle in spring, with pink flowers on the road, London suburbs, United Kingdom

Visit the majestic Windsor Castle

        Fancy getting a glimpse inside the world’s largest occupied castle? Windsor Castle is over 900 years old and is said to be Queen Elizabeth’s II favourite weekend digs. It has a whopping 1,000 rooms, 300 fireplaces and magnificent gardens. Windsor is also said to be the most haunted royal residence and there are plenty of ghost stories that’ll make your hairs stand on end. Keep an eye out for the royal flag – if it’s up you know the Queen is home!

Landscape of Little Missenden nature and river Misbourne, Chilterns, Buckinghamshire, England

Cycle the lush Chiltern Hills

        Load your daysack with snacks and set off for a fun day of exploring on two wheels. Cycle through the rolling green Chiltern Hills and the gorgeous Hambledon Valley before reaching Windsor. Although the Chilterns are an Area of Outstanding Natural Beauty, there are plenty of spots that are still a bit of a local secret – from bluebell-blanketed forests and secluded villages to Roman ruins and centuries-old stately homes.

A great trip that covers a lot of must see locations. Given it is rated as an ‘original’ tour, we were pleasantly surprised by the standard of accommodation included. Given we are both in our 60’s and this being our first ever organised tour, we did find it a little too long and hectic. But well worth it nonetheless! We now know where we would love to visit again sometime in the future.

This trip was just what I had hoped for — riding through the beautiful countryside (especially on the trains) and visiting lots of towns throughout the UK.

Want a small group getaway that requires little organisation on your part? Is led by competent, friendly and knowledgeable locals? Won't break the bank? Introduces you to like-minded friendly folk? Is kind to the environment? Leaves you wanting more of the same? Intrepid is the answer.

Disappointed with the trip, especially given the huge costs associated, some hotels sub-par, tour guide was nota local, lacking knowledge. Also Intrepid led us to believe the transfer to the second trip to Ireland was to be arranged by Intrepid, this was not the case.
