Looking for unforgettable ways to keep the kids entertained during the school holidays? Whether you’re planning a weekend getaway or a full-blown family staycation, Dorset has you covered. With its spectacular coastline, family-friendly beaches, and an impressive line-up of water-based attractions, it’s no surprise that “Dorset water park” is one of the top-searched summer activities in the UK.
From giant inflatables to spiralling flumes and exhilarating slip-and-slides, here are three must-visit waterparks in Dorset. Plus, we’ve included nearby places to stay and even more water-based adventures to help you plan your most exciting summer yet.
Tucked beneath the dramatic ruins of Corfe Castle, Dorset Adventure Park is a one-of-a-kind family destination. Set within 150 acres of scenic woodland, this waterpark offers two spring-fed lakes filled with over 200 metres of inflatable obstacle courses. You’ll find floating trampolines, slides, balance beams, and climbing walls — all designed to test your agility and keep the adrenaline flowing.
But the adventure doesn’t stop at the water’s edge. The park also features a wildly popular 2km Mud Trail, packed with over 50 obstacle challenges. Expect to crawl, climb, slide and swing your way through the forest as you wade through muddy trenches and navigate cargo nets. It’s high-energy, hilariously messy fun that both kids and grown-ups love.
Families love it here because it combines the thrill of a waterpark with the team spirit of an outdoor adventure course. Sessions are supervised, and all safety equipment — including wetsuits and buoyancy aids — is provided. Kids from age six and up can join in, making this a perfect option for active families looking for something beyond the usual beach day.

For classic waterpark thrills with a coastal twist, look no further than Splashdown Poole. Located in the lively Tower Park complex, this water wonderland features 13 heart-pounding rides—both indoor and outdoor—making it a great all-weather option. Favourites include the twisting tunnels of Dragon’s Lair, the stomach-churning Screamer, and the pitch-black plunge of Black Thunder.
Younger visitors aren’t left out. The Little Buccaneers SplashZone offers shallow pools, mini flumes, and interactive water play features that are ideal for toddlers and younger children. Families can easily split up and explore different zones, with teens heading for the thrill rides while younger kids stay safe and entertained in their own water playground.
The atmosphere is energetic and family-friendly, with plenty of food outlets nearby and other attractions in the Tower Park complex like bowling, a cinema, and arcades — perfect for turning a day at the waterpark into a full family outing.

If you’ve never flown down a 150-metre inflatable slide before, this is your chance. The Mega Slip and Slide in Corfe Mullen is home to the longest slip-and-slide in the UK, and it delivers every bit of the high-speed fun the name suggests. Set against a gentle hillside and surrounded by lush Dorset countryside, this seasonal attraction is ideal for sunny-day adventures.
Start from the 11.5-foot (3.5-metre) launch platform and choose your ride: an inflatable ring, a bodyboard, or just yourself. Then it’s time to zoom down the slope, hit the splash zone, and race your friends back to the top. With different lanes and slide types, it’s an experience the whole family can enjoy — from confident teens to younger kids getting their first taste of the action.
Mega Slip and Slide is open daily during the summer and offers on-site parking, picnic tables, and a small café for snacks and drinks. It’s a fantastic day out if you’re after simple, wet-and-wild fun without the complexity of larger parks.
📍 Location: Mill Street, Corfe Mullen, Wimborne, BH21 3RH

If you’re not quite ready to towel off after your Dorset water park adventures, don’t worry — Dorset has no shortage of watery wonders beyond the slides and splash zones. Whether you’re seeking tranquil swims, exhilarating water sports, or breathtaking coastal views, there’s something here for every kind of explorer.
If you’re drawn to water adventures that are slower-paced and surrounded by nature, wild swimming in Dorset is a perfect way to unwind and explore. The county’s diverse landscape offers stunning swim spots, from dramatic sea arches to peaceful inland rivers. One of the most iconic locations is Durdle Door, where the crystal-clear water and striking limestone arch provide a scenic and refreshing swim. It’s best suited for confident swimmers, as the beach shelves steeply and conditions can vary. Always swim with care and ideally with someone else nearby.
For families or those looking for a gentler experience, the River Frome near Wareham offers calm, shallow waters and grassy banks ideal for paddling and picnicking. It’s a local favourite for wild swimming thanks to its slow current and accessible entry points. Whether you’re floating downstream or letting the kids splash in safety, it’s a hidden gem for warm summer afternoons. Inland rivers like this offer a peaceful contrast to the often livelier beaches along the coast, and are perfect for a more tranquil day out.
If swimming isn’t on your agenda but you still want to enjoy the water, Dorset’s coastline offers plenty of opportunities to take to the sea by boat. The Brownsea Island Ferry, departing from Poole Quay, is a short and scenic ride that provides incredible harbour views. Once on the island, you can explore wooded trails, sandy shores, and perhaps even spot one of the resident red squirrels. It’s a relaxed, low-effort outing that’s great for multi-generational groups or families with little ones.
For longer excursions, City Cruises Poole runs guided trips along the Jurassic Coast, past landmarks like Old Harry Rocks. These cruises are ideal for soaking up the region’s natural history, with live commentary often provided. If you’re after something with a bit more speed and excitement, you can book a private RIB tour, which zips along the cliffs and bays for a more high-octane take on sightseeing. These coastal journeys are a fantastic way to experience Dorset from a new perspective — without needing a swimsuit.
One of the most accessible and educational water-based activities in Dorset is rockpooling. Great for kids and curious adults alike, it offers hands-on discovery in a safe, fun setting. Head to Charmouth, Swanage, or Kimmeridge Bay, where low tide reveals a miniature world of crabs, anemones, sea snails, and starfish. All you need is a bucket, some patience, and a sense of adventure. It’s a brilliant way to connect younger children with nature and encourage safe exploration.
If your kids are a bit older or already confident in the water, consider bringing snorkelling gear along. Places like Lulworth Cove and Chapman’s Pool offer calm, sheltered bays with surprisingly clear water and fascinating underwater life. You’ll often spot small fish weaving through seaweed or explore hidden rocky nooks just offshore. Snorkelling builds water confidence and adds an exciting new layer to a beach day — and you don’t need any expensive equipment to get started.
For families looking to add adrenaline into their seaside stay, coasteering is one of Dorset’s most thrilling outdoor activities. Blending wild swimming, scrambling over rocks, and the occasional cliff jump, it’s a fantastic way to experience the coastline up close. With expert guidance from companies like Land & Wave or Jurassic Watersports, beginners and older kids (typically 8+) can safely explore hidden caves, leap into deep pools, and learn about the geology and wildlife of the Jurassic Coast.
Coasteering takes place in stunning locations like Dancing Ledge and Swanage Bay, where clear water and dramatic cliff faces provide the perfect natural playground. Sessions are designed to suit different ability levels, and wetsuits, helmets, and buoyancy aids are all provided. It’s an empowering, energetic experience that turns the landscape into a giant adventure course — one that your kids (and you) won’t soon forget. For confident swimmers who love a challenge, this is a highlight of any Dorset holiday.
Dorset isn’t just a destination — it’s a summer playground bursting with variety. From the rush of an inflatable waterpark to the serenity of wild swimming, from kayaking adventures to discovering crabs in a rockpool, this coastal county offers countless ways to dive into unforgettable family experiences.
Whether you’re raising mini thrill-seekers or just want to float and relax, Dorset water parks and its diverse range of water activities promise something to suit every kind of summer story.
