From soft play and indoor adventures to museums, libraries and community activities, Hampshire has options for children of all ages. Better still, you don't necessarily need to spend a fortune. A smaller activity can be combined with a paid attraction, while museums and community venues can provide a budget-friendly way to fill a wet afternoon.

• Rainy day? No problem. Hampshire has plenty of indoor activities for kids, from soft play and climbing to museums, libraries and creative activities.

• Looking for something active? Rock Up Whiteley combines climbing, indoor adventure and soft play, making it a great option for families with children of different ages.
• Keep costs under control. Mix paid attractions with free activities such as libraries, museums and community events, and look out for family tickets, off-peak sessions and online discounts.

Whatever the weather, there’s plenty to discover. From Southampton and Portsmouth to Winchester, Basingstoke and the New Forest, Hampshire offers indoor family activities for every kind of day out.

When the weather isn't playing ball, indoor play centres are an easy way to give children space to run, climb and explore. Hampshire has indoor venues spread across several towns, so there's usually an option within a reasonable drive.

For families planning family days out in Hampshire, soft play and indoor adventure centres can also be particularly useful when siblings are different ages. Many venues have separate areas for younger and older children, while adventure centres can offer activities that appeal to the whole family.

Southampton is one of Hampshire's biggest hubs for indoor family entertainment. The city and surrounding area offer traditional soft play alongside more active options, giving parents plenty of choice when the weather turns wet.

Just outside Southampton, Rock Up Whiteley combines playful climbing with indoor play. Based at Whiteley Shopping Centre, the venue has climbing walls and challenges for children from four years plus, alongside soft play and even some climbing sessions aimed at younger visitors. It's a useful option for families with children of different ages, particularly when you're looking for something more active than traditional soft play.

In Portsmouth, families can choose from a number of indoor play centres and activity venues. Soft play is particularly popular for younger children, while older kids have options including climbing, trampolining and other indoor adventure activities.

Portsmouth's location also makes it possible to combine an indoor attraction with other family-friendly activities around the city. If you're planning a full day, check what's happening at local museums and attractions before setting off.

Winchester has a slightly different feel, with a mixture of indoor children's activities, leisure facilities and cultural attractions. It's a good choice for families who want to combine active play with a museum or historic attraction.

Further north, Basingstoke is another useful base for indoor family activities. The town has leisure and entertainment facilities alongside soft play and other children's attractions, making it worth considering when the weather rules out outdoor plans.

The New Forest and surrounding towns also have indoor play centres and family attractions. These can be particularly useful if you're staying in the area and the rain puts a stop to plans for a woodland walk or day exploring the coast.

Indoor attractions can become very busy during weekends and school holidays, particularly when the weather is poor. Before travelling, check the venue's latest opening hours and whether you need to book.

Some useful things to check include:

Age restrictions: Make sure the venue has activities suitable for your child's age. At Rock Up, we run climbing sessions from age 4 and up with no upper age limit. Plus out Toddler Climb & Play sessions are perfect for under 4's.
Session times: Some attractions operate timed sessions rather than allowing all-day access.
Adult supervision: Find out whether adults need to remain on site or participate. We, for example, need one adult to stay in the arena for every four children. (Unless a member or when using our Academy Drop-Off sessions)
Booking: Popular venues may sell out during school holidays or rainy weekends. It's best to check online or even book online to help with this.
Clothing: Active attractions usually work best with comfortable clothes and suitable footwear.
Food: Check whether there's a café, restaurant or nearby food option.
Parking: This can be particularly important when visiting larger attractions or shopping-centre venues.

Prices vary significantly across Hampshire. Traditional soft play is generally one of the more affordable paid activities, while specialist attractions and longer sessions can cost more.

If you're visiting regularly, look out for memberships, multi-visit passes and family tickets. These can make a significant difference if you have several children or expect to return during the school holidays.

A family day out doesn't have to involve an expensive attraction. Hampshire has plenty of rainy day activities in Hampshire that are free or inexpensive, particularly if you know where to look.

Libraries, community centres and local councils regularly provide activities for children, while some museums and public spaces offer free admission or free family events.

Your local library can be an underrated option for a rainy afternoon. Libraries across Hampshire and Southampton regularly run children's activities such as story times, craft sessions and holiday events.

They also provide something that many paid attractions don't: a quiet, warm place where children can spend time without needing to follow a fixed itinerary.

Check the website of your local library or council for what's coming up. Activities can vary between towns and often change during school holidays.

Community centres are another place worth investigating. Many host children's clubs, craft sessions, play groups and family events, some of which are free or available for a small charge.

For families with younger children, keep an eye out for stay-and-play sessions. These often give toddlers a chance to play with age-appropriate equipment while parents and carers can meet other local families.

Museums can also be surprisingly budget-friendly. Some local museums have free general admission, although special exhibitions, workshops or events may carry an additional charge.

If the weather is only mildly miserable rather than completely torrential, consider combining an indoor activity with a short outdoor stop. A quick walk followed by a library visit, café or museum can make a full afternoon without requiring multiple paid attractions.

The easiest way to reduce the cost of a family day out is to avoid making every activity a paid one.

For example, you could start with a free library activity, bring a packed lunch, then spend the afternoon at one paid attraction. Alternatively, visit a museum in the morning and use a local park or free public space when the weather improves.

A few other ways to keep costs down:

Look for family tickets rather than buying individual admission.
>Check off-peak sessions, which can sometimes be cheaper.
>Book online if the attraction offers an online discount. Look for multi-visit passes if you're likely to return.
>Purchase your activity and food from the same location, rather than moving spots.
>Check local council websites for free holiday activities.
>Compare the total cost, including parking, food and extras, rather than just the admission price.
>Look for combination tickets if you're planning to visit more than one attraction.

It can also be worth joining local parenting groups or signing up to venue mailing lists. Free events and temporary activities are often advertised there before they become widely known.

Museums are a great alternative when you want your children to do something entertaining and educational at the same time. Hampshire's history provides plenty of subjects to explore, from aviation and transport to maritime history and ancient archaeology.

If you're wondering what are the best indoor activities for kids in Hampshire, museums are particularly useful because they can work for a wide range of ages.

Museums kids will actually enjoy

SeaCity Museum in Southampton is a strong choice for children interested in ships, the sea and dramatic stories from the past. Its exhibitions explore Southampton's maritime history and its connection to the Titanic, with interactive displays and multimedia elements helping younger visitors engage with the subject.

Solent Sky Museum, also in Southampton, is ideal for children who are fascinated by aircraft. The museum focuses on aviation in the Solent region and houses historic aircraft, including a Spitfire. The combination of real aircraft and local history gives children plenty to look at rather than relying solely on traditional museum displays.

In Portsmouth, the National Museum of the Royal Navy offers a chance to explore the city's strong maritime heritage. The wider Historic Dockyard site includes historic ships and museums, although individual attractions may have separate admission charges. Children who love ships, sailors and stories of naval history can easily spend several hours exploring.

Winchester City Museum is another option for families interested in local history. Its displays cover Winchester's development from Roman times onwards and can provide an introduction to the city's past before heading out to explore the historic centre.

For aviation enthusiasts, The Museum of Army Flying at Middle Wallop offers another option further into the county. Its collection includes helicopters, fixed-wing aircraft and other exhibits exploring the history of army aviation.

When choosing a museum, think about what your child is already interested in. A dinosaur enthusiast might be captivated by archaeology, while a child obsessed with vehicles could happily spend hours looking at aircraft, ships or historic transport.

Different ages require very different types of entertainment, so it's worth filtering your options before deciding where to go.

Toddlers generally benefit from activities where they can move around freely. Soft play, stay-and-play groups, story sessions and short museum visits are good choices. Look for venues with dedicated toddler areas and don't worry about trying to make the activity last all day.

Primary-school children have the broadest range of options. They can enjoy soft play and climbing but are also old enough to appreciate museums, cinemas, creative workshops and interactive attractions. This is a good age to experiment with different activities and discover what interests them.

Teenagers can be harder to entertain, particularly if they have outgrown traditional children's attractions. Look for activities that provide independence, challenge or something new to learn. Indoor climbing, specialist museums, cinemas, creative workshops and escape-room-style activities can all be worth considering, depending on age requirements.

Don't be afraid to mix age groups, either. A museum with interactive exhibits can work surprisingly well for both younger and older children, while an active attraction can give siblings the opportunity to challenge themselves at their own level.

What are the best indoor activities for toddlers in Hampshire?

Soft play and stay-and-play sessions are often the easiest choices for toddlers, particularly when they need somewhere safe to explore and burn off energy. Libraries, story sessions and shorter museum visits can also work well. Look for activities that allow toddlers to move around rather than expecting them to sit still for long periods.

Are there free indoor activities for kids in Hampshire?

Yes. Libraries, community centres and some museums provide free activities or events for children and families. Local councils and individual venues also advertise free school-holiday activities throughout the year, so it's worth checking what's available in your area before booking a paid attraction.

What are the best rainy day activities in Hampshire for families?

There are plenty of rainy day activities in Hampshire, including soft play, indoor climbing, museums, cinemas, libraries and creative workshops. The best choice depends on your children's ages and energy levels. An active attraction can be ideal after a week spent indoors, while a museum or cinema may suit a quieter afternoon.

Where can I find indoor activities for kids in Hampshire during the school holidays?

Check local attraction websites, council event pages, libraries and community centres for what's happening during the holidays. Booking popular attractions in advance is recommended, particularly during wet weather when indoor venues tend to be busier.

Plan your next indoor family day out in Hampshire

Hampshire is a large county, but that means families have plenty of choice when the weather turns against them. From Southampton and Portsmouth to Winchester, Basingstoke and the surrounding towns, there are indoor options for every kind of family.

For energetic children, soft play, climbing and adventure centres provide somewhere to run, jump and explore. Museums and cultural attractions offer something more educational, while libraries, community centres and free events can help keep the cost of a family day out under control.

The trick is to choose activities based on your children's ages and interests rather than simply looking for the biggest attraction. A toddler may be perfectly happy with an hour of soft play and a story session, while an older child might prefer spending an afternoon climbing or exploring an aircraft museum.

So next time the rain starts, don't assume your plans are ruined. There are plenty of indoor activities for kids in Hampshire waiting to be discovered.
