25 Free and Cheap Things to Do with Kids in Dorset This Summer (2026 Guide)

Keeping the kids entertained throughout the summer holidays doesn't have to cost a fortune. Some of our favourite family adventures in Dorset are completely free, while others cost little more than an ice cream or bus fare.

From fossil hunting and beach days to woodland walks and hidden historical gems, here are 25 of our favourite free and budget-friendly things to do with kids in Dorset this summer.

1. Fossil Hunting in Charmouth

The Jurassic Coast is one of Dorset's greatest treasures and Charmouth is one of the best places to search for fossils. Bring a bucket and see what prehistoric treasures you can find along the beach. 

2. Spend a Day at Knoll Beach, Studland

With soft sand, shallow water and plenty of space to play, Knoll is one of our favourite beaches for a family day out.  Free parking if you have a National Trust membership but I'd recommend getting there early as it gets busy. Look out for the ice cream boat in the Summer!

Even cloudy days are fun at the beach

3. Explore Upton Country Park

With beautiful gardens, woodland walks, a children's play area and lots of open space, Upton Country Park is perfect for a low-cost day outdoors. The fountains in the Walled Garden are fab on a hot day!

4. Go Rock Pooling at Kimmeridge Bay

Armed with a net and a bucket, kids can spend hours discovering crabs, fish and other marine creatures hidden among the rocks. The carpark is privately owned costs £6 per car. 

5. Walk to Old Harry Rocks

This classic Dorset walk rewards you with some of the most spectacular coastal views in the county. Suitable for all ages and levels of fitness, it's a lovely amble up to the top.  Finish up with a nice cold drink in the Bankes Arms and enjoy the view. 

6. Enjoy a Picnic in Poole Park

Pack a lunch, feed the ducks and let the children burn off some energy in one of Dorset's most popular parks. There are two play areas - the smaller one by the Ark is best for young children, whilst the larger one at the other end is great for older kids. 

7. Cycle Around Holes Bay

If you're looking for an easy family bike ride, the route around Holes Bay is a great choice. The relatively flat cycle paths make it suitable for children, while the views across the water and chances to spot wildlife keep things interesting. It's a great way to get some fresh air, burn off energy and enjoy a different view of Poole Harbour without spending a penny.

8. Experience Wareham Wednesdays

If you're visiting Dorset during the summer holidays, don't miss the famous Wareham Wednesdays. One of the highlights is the pirate invasion, when swashbuckling pirates arrive in town by boat and have a huge waterfight with the locals on the riverside.  There are family activities, entertainment, live music and plenty of opportunities for children to join in the fun. Best of all, many of the events are free, making it a fantastic budget-friendly evening out for families. Bring your water pistols! 

9. Explore Moors Valley Country Park

With beautiful forest walks, cycle routes and plenty of places to stop for a picnic, it's easy to spend a whole day at Moors Valley without spending a fortune. This Summer, Families can enjoy the magical Room on the Broom trail, where children can follow the story through the woods and search for familiar characters along the way. There's also a brilliant play trail packed with climbing equipment, balancing challenges and woodland adventures that can keep kids entertained for hours. Free entry but there is a charge for the carpark.

11. Treat Yourself to Chips in Swanage

After a walk around Durlston Country Park, head down into Swanage for a well-earned portion of chips by the seafront. Find a bench, take in the sea views, and enjoy a simple but perfect family moment watching the boats and beach life drift by. 

12. Step Back in Time at Tyneham Village

Tyneham is one of Dorset’s most fascinating places to explore — a deserted village frozen in time since World War II. Families can wander through the old school, church and cottages while learning a little piece of local history along the way. If you’re up for a walk, you can continue down the valley to Warbarrow Bay, a stunning hidden beach that feels wild, remote and completely untouched. It’s a bit of a trek, but well worth it for the views and sense of adventure.

13. Visit Pamphill Dairy Farm Shop

Pamphill is a lovely little stop for families, especially if you’re exploring the wider Wimborne area. Alongside the farm shop, there’s a brilliant new play area where children can let off steam while you enjoy a slower pace for a moment. And no visit is complete without one of their amazing ice creams — the perfect treat after a countryside walk. 

The ice cream flavours change regularly so you never know what you're going to find here!

14. Watch the Sunset at Sandbanks

Sandbanks is a great spot to finish the day, especially in the evening when it’s quieter. Head down to the harbour and you’ll get clear views across the water as the sun goes down. It’s an easy, low-cost way to end a day out, and a good chance to slow things down before heading home. 

15. Catch the Open-Top Bus to the Beach

The journey is part of the fun and children love sitting upstairs enjoying the views. You can the catch the Harbour Breezer 60 from Poole Bus Station and this will drop you off by Sandbanks Beach. 

16. Wander Around Kingston Maurward Animal Park & Gardens

These beautiful gardens offer lakes, wildlife and plenty of space for children to explore. You can see a variety of farm animals up close, including goats, pigs and donkeys. Free entry but there is a £5 carpark charge

17. Walled Garden Moreton and a River Paddle

Moreton is a great combination stop for families, starting with a wander around the walled garden and its peaceful surroundings. Entrance is only £4 for adults and under 18's go free. After exploring the garden, head down to the nearby river where there are shallow spots that are perfect for paddling on a warm day. It’s an easy, low-cost outing and perfect for cooling off on those long hot Summer days. Tip - pack water shoes as it's a bit stony in the river.

18. Visit Poole Museum

Poole Museum is a great free indoor option for families, especially if you need a break from the weather or a change of pace from outdoor activities. It’s small enough to explore without it feeling overwhelming for children, with exhibits that help bring the history of Poole’s maritime past to life. A simple, easy stop that works well as part of a budget-friendly day out in the town. If your budget allows, I'd recommend heading across the street to Truly Scrumptious where you can find all kinds of sweets and treats. 

19. Go Crabbing at Lake Pier

One of our favourite Summer holiday activities when on a budget! A bucket, a line and some bait are all you need for hours of entertainment. The views from Lake Pier are fantastic - and look out for the low flying Chinook helicopters coming and going from the nearby Military base. 

20. Spend the Day at Hamworthy Park and Beach

With a playground, toddler friendly paddling pool, beach, green space and stunning harbour views, Hamworthy Park is a brilliant budget-friendly day out. There is free parking in nearby roads but these do get busy so would advise coming early. 

21. Explore Tout Quarry Sculpture Park

Combining art, history and outdoor adventure, this hidden gem on Portland is well worth a visit. 

22. Walk the Sika Trail in Wareham Forest

A family-friendly woodland trail with plenty of opportunities to spot wildlife along the way. Great for bike rides, dog walks or just getting out in the fresh air. 

23. Take the Jurassic Breezer Bus to Durdle Door

The Jurassic Breezer bus (30)  is a great budget-friendly way to reach Durdle Door without the stress of parking. The journey itself is part of the experience, with some brilliant views along the way including the majestic ruins of Corfe Castle. It’s an easy option for families and means you can enjoy one of Dorset’s most iconic landmarks while keeping things simple and relaxed. Return tickets are £6 from Swanage.

24. Discover Maiden Castle

Maiden Castle is one of the largest Iron Age hill forts in Europe and a great place for families who enjoy a bit of space to explore. The vast grassy ramparts are perfect for walking, running and letting kids use their imagination while taking in the views across the surrounding countryside. It’s a simple, free day out that also gives a small glimpse into Dorset’s ancient history.

25. Walk Shutes Lane

Shutes Lane, often linked with the nearby Hell Lane, is a quiet countryside walk with a slightly eerie twist thanks to the carved “faces” you can spot along parts of the route. The tall hedgerows and narrow path give it a tunnel-like feel, while the details in the banks make it interesting for children to look out for as they go. If you're feeling energetic, why not head up nearby Colmers Hill afterwards - one of the Dorset's most photographed spots. 

Climbing Comers Hill
