St Andrews Lakes in Kent, or the Blue Lake, as locals call it, is so tucked away in the village of Halling, you’d never guess it’s there.

Hidden away from the busy roads in Medway, lies an emerald blue lake where laughter replaces the blare of horns. When you see the lake, it’ll take you by surprise. (I’d bet that most people going here for the first-time have a “Wow…I can’t believe this is here!” moment. I certainly did.)

Surprisingly, my discovery of this little oasis wasn’t from TikTok, IG or Facebook. It was actually completely accidental. I was walking in the area, searching for the North Down’s Way, when I made stumbled upon St. Andrews Lakes.

I’ve now pulled created a guide on visiting St Andrews Lakes with a review of my experience and tips on what you should know before you go. Hopefully this is helpful ahead of your visit!

About St Andrews Lakes

St Andrews Lakes in Kent is a quarry lake. The area used to be chalk quarry. Then they created something really special here instead: a recreational lake and divers’ playground.

Meet St. Andrews Lake and Watersports Centre.

The instant you arrive a few questions are guaranteed to pop into your mind…

How deep is St Andrews Lakes in Kent?

St. Andrews Lakes in Halling, Kent is around 35 meters deep.

How is the water at St Andrews Lakes so blue?

The emerald blue water at St Andrews Lakes is caused by refraction of the limestone deposits suspended in the old quarry lake.

This intense blue-green colour effect from the mineral deposits of limestone rocks can be seen in famous lakes around the world. For instance, look up photos of Bear Lake in Utah (USA), Plitvice Lakes in Croatia, or my personal favourite: the turquoise pools in Semuc Champey, Guatemala.

What you need to know when visiting St Andrews Lakes

After going to St Andrews Lakes, I am a fan. Spending a couple hours here is one of the best things to do in Kent this summer.

Ahead of the day you plan to visit, be sure go to their website and book in advance. Especially in the summer. When I read reviews online, there were a few unhappy persons complaining about this requirement. On the contrary, I love that they do this. Here’s why…

An advanced booking system and hourly slots regulates the number of people on the premises, including the lake. Which means that as busy as the place gets, it doesn’t feel over-crowded. You do not have to worry about getting a good spot on the beachfront nor out on the water.

Parking and facilities at St Andrews Watersports Centre

There is a large carpark at the watersports centre. Parking at St Andrews Lakes will not be an issue.

There are a few waterfront tables out on the sand. The No Picnic signs aren’t exactly a welcome sight but I guess it keeps beach litter to a minimum and encourages on-site commerce. A small café, The Beach Hut is located further inland and has outside seating.

Lockers are available to store your personal effects in.

Things to do at St Andrews Lakes in 2025

There were people of all ages enjoying themselves at the lake when I went: families, couples, young people, older folks.

Everyone is scattered across the venue. Some are out on the water with kayaks, pedalos, paddleboards, at the Aqua Park, or chilling on the beach or at the café.

Besides water-based activities, there is also rock-climbing, ziplining, archery and a spa.

Everything at St Andrews has major appeal. But for me, nothing held more allure than the kayaks lying at the water’s edge. They were definitely singing “C’mon on over!”

Review: Kayaking at St Andrews Lakes

I rented a single seat kayak directly on their website. It is an easy booking process where you simply select the time slot and pay online. Double kayaks, family kayaks (3 people) and bell boats for up to 6 are all available at hourly rates.

They request that you arrive 45 minutes prior to your scheduled time of booking. So I arrived 45 minutes, no sweat.

My experience was an efficient check-in and kayak pick-up service. The watersports station is impossible to miss on the beachfront.

It didn’t take long to get a feel for the kayak, despite it being over 3 years since my last date with paddles. It was nice and roomy in the kayak. My only gripe is that they do not have not much of a built-in back rest which can exert strain on your lower back. You’ll want to stretch afterwards.

Amazingly, I managed not to get too much water in the kayak – though yes, your bum will 100% get wet!

If you’re a watersports veteran with your own kayak, they also offer the ‘Bring Your Own’ kayak option for a small fee.

Pedalo rentals and paddleboarding at St Andrews Watersports

Paddle boarding appeared to be the favourite activity on the lake.

There were also a few families sporting big smiles as they made the rounds in hard-to-miss pedalos.

St Andrews Aqua Parks, Kent

St Andrews Lakes also has 2 Aquaglide Parks which are really popular.

There is a kids aqua park for ages 2 – 6 and the main aqua park for the big kids above age 6. Session prices and times are on their website.

Beach at St Andrews Lakes

St Andrews Lakes also has a man-made sandy beach, with beach chairs and parasols available.

All day access passes for the beach at St Andrews Lakes can be booked online. (Adult and Children prices. Under 2’s are free.)

Swimming at St Andrews Lakes

The lake has a depth of 35m.

This is a good option for qualified swimmers seeking open water venues.

For those less-experienced, it is well worth mentioning here that quarry water is exceptionally cold. Freezing water poses a real threat of shock so it’s always prudent to proceed with caution. Wetsuits are available for rental at St Andrews Lake watersport centre and guidance for swimmers is all laid out on their website.

The St Andrews Lakes website also promotes scuba-diving, fishing, sailing, climbing and even bootcamp fitness sessions.

Their 30-minute Clip & Climb sessions can be booked either in advance or on-site.

Opening hours at St Andrews Lakes

St Andrews Lakes is open every day from 10am.

Staff and Safety

Watersport locations need to be well-staffed for obvious safety reasons – St Andrews Lakes proved to be no exception.

I was met by a pleasant security guard at the entrance and assisted by efficient personnel at the check-in station. There were watersports guides stationed both on the waterfront and out on the lake to assist with our equipment needs and generally keep an eye on things.

The guide stationed on the water even “assisted” a few folks who were running over their assigned time with getting back to shore. Don’t worry, they’ll make sure you don’t lose track of time…

Other nearby places of interest in Kent’s North Downs

The Blue Lake in the village of Halling is located nearby several other top attractions in Kent, especially ones appealing to outdoor enthusiasts and history buffs.

Several of these local attractions caught my eye purely by chance while en route to St Andrews Lakes.

Historic Rochester: Walk over Rochester Bridge & See Rochester Castle

While travelling on the West Malling A228 road, you can easily spot the distinguished structure of Rochester Castle beside the River Medway.

Rochester is a former Roman fortified town and a good place of historical interest in Kent to visit. The intrigue begins as early as when you enter the town via the medieval Rochester Bridge. It’s a cool bridge to walk along to admire the architecture as well as the view.

North Downs Pilgrim’s Way

I also noticed signs pointing to “Pilgrim’s Way”.

North Downs is probably best known for its National Trail which follows the pilgrims’ journey from Winchester to Canterbury.

North Downs Way, or North Downs Pilgrim’s Way, is a historical route that rewards hikers or cyclists with absolutely spectacular scenery.

Ranscombe Farm Nature Reserve

Ranscombe Farm is located minutes away from St Andrews Lakes by car. It is a gorgeous nature reserve – think endless expanses of wild flowers and handsome cattle dotting its fields.

One of the unexpected pleasures of being on Ranscombe Farm is discovering the views over the Medway Valley and the Weald of Kent. A classic example of why the Kent county is referred to as the ‘Garden of England’.

Final thoughts: is visiting St. Andrews Lakes worth it?

Yes, St Andrews Lakes is a fun place to visit. I’d recommend enjoying it over 1-2 hours. However, you will want to keep in mind that it can get quite expensive over several hours. Most activities go for an hourly rate and, even if you opt to skip those, there will be a charge to lounge on the beach.

Overall, St Andrews Lakes has been a welcome sporting addition to an area of North Kent which mainly attracts walkers who are following the North Down’s Way.

Best of all, they are continuously developing the park which means even more fun activities in Kent to look forward to this summer!
