During extreme heat, indoor attractions with air conditioning remain the safest and most pleasant to visit. Think museums, cinemas, climbing gyms, and arts and cultural experiences that take place entirely indoors. Outdoor attractions such as theme parks and zoos may experience difficulties or even temporarily close in extreme temperatures. In this article, we answer the most frequently asked questions about what you can do when the thermometer rises.
What types of attractions are heat-proof?
Heat-proof attractions are fully covered, cooled indoor venues that are not dependent on outdoor temperatures. Museums, cinemas, escape rooms, bowling alleys, climbing gyms, and arts and cultural experiences fall into this category. They operate at full capacity regardless of the weather and offer visitors a comfortable environment, even when it’s 35 degrees outside.
The distinction lies in the infrastructure. An attraction that operates entirely indoors with a well-functioning climate system is not dependent on the weather. Outdoor attractions such as theme parks, zoos, and outdoor festivals are: they may adjust their opening hours in extreme heat, limit activities, or advise visitors to avoid certain time slots.
Within the category of heat-proof attractions, there are also gradations. A shopping centre is cooled but offers little activity. A physical arts and cultural experience such as a maze combines movement, sensory stimulation, and a controlled indoor climate. That makes it not only a pleasant choice in warm weather, but also a substantively rich destination.
Which indoor attractions have air conditioning?
Most professional indoor attractions in the Netherlands are equipped with air conditioning or climate control. Cinemas, museums, escape rooms, virtual reality centres, and physical art experiences generally have a fully regulated indoor climate. The temperature remains constantly pleasant, regardless of the outdoor temperature.
At Doloris, we actively ensure that both Meta Maze in Tilburg and Anoma Maze in Utrecht are climate-controlled. No matter how warm it is outside, we do our best to keep the temperature as cool and comfortable as possible indoors. The outdoor temperature has little influence on the indoor environment. After your visit, you can also relax in our cooled lounge with a drink.
Please note: even if a venue is cooled, if you are physically active, you can still get warm. In a maze, you are constantly moving: walking, crawling, and climbing. We therefore advise visitors to wear light clothing so that you remain comfortable during the experience.
What are the best days out during extreme heat in the Netherlands?
The best days out during extreme heat in the Netherlands are activities that take place entirely indoors and apply active climate management. Good options include: a visit to a museum, an afternoon at the cinema, a climbing gym, an escape room, or a sensory arts and cultural experience. They offer both cooling and substantive value.
Below is an overview of popular choices:
- Museums and galleries: cooled, relaxed, and culturally enriching
- Cinemas: fully cooled, passive entertainment
- Climbing gyms and bouldering centres: active, indoors, generally ventilated
- Escape rooms: cooled, interactive, and time-limited
- Sensory art experiences: such as a maze with climate control, where you explore at your own pace
The advantage of an activity like an art maze is that you take your time with it. You decide how long you stay and which route you take. That makes it an excellent choice for a longer afternoon indoors, without it feeling passive.
Which outdoor attractions are dangerous in extreme heat?
In extreme heat, outdoor attractions with little shade, long queues, or intensive physical activity are the most risky. Theme parks, outdoor swimming pools, festivals, zoos, and outdoor sports activities can lead to overheating, dehydration, or heat stress at temperatures above 35 degrees, particularly in children and the elderly.
The risk factors at outdoor attractions are:
- Long periods in direct sunlight without shade
- Queues on asphalt or concrete, which radiate extra heat
- Insufficient drinking water provision
- Intensive physical exertion in full sun
- Poor ventilation in overcrowded spaces
Many Dutch attractions adjust their policies during extreme heat: they open earlier, close sooner, or advise visitors to avoid the afternoon. Always check the website of your destination in advance if a heatwave is expected.
How do you choose a safe activity on a hot day?
You choose a safe activity on a hot day by paying attention to three key factors: location (indoors or outdoors), climate control, and physical exertion. Preferably choose a fully covered venue with active cooling, wear light clothing, and plan your visit outside the hottest hours of the day.
Practical checklist when choosing a day out during heat:
- Is the venue fully indoors? If so, check whether air conditioning is present.
- How physically active is the activity? More movement means more heat production, even indoors.
- Is there a quiet space to recover? A lounge or seating area is a bonus.
- How long does the activity last? Shorter sessions are easier to sustain in warm weather.
- Is the venue easily accessible without standing in the sun for a long time? Think about parking and walking distance.
A sensory art experience in a cooled maze scores well on all these points. You are indoors, the climate is controlled, you set your own pace, and a cooled lounge awaits afterwards. Whether you choose a relaxed museum visit or a more active exploration: it always comes down to a combination of comfort, safety, and an experience that is worth it.
Frequently Asked Questions
Do I need to book in advance at indoor attractions during a heatwave?
Yes, booking in advance is strongly recommended. During heatwaves, many people simultaneously seek refuge in cooled indoor venues, meaning popular attractions such as escape rooms, art experiences, and climbing gyms fill up faster than usual. Book your tickets well in advance online to avoid disappointment.
What should I bring to an indoor attraction on a hot day?
Wear light, breathable clothing and bring enough water, even if the venue is cooled. If you are physically active — such as in a maze or climbing gym — you will still generate heat. A small snack, comfortable shoes, and possibly a spare shirt can make the difference between a pleasant and a tiring experience.
Are indoor attractions also suitable for young children and the elderly during extreme heat?
Absolutely, indoor attractions with climate control are particularly well-suited for vulnerable groups such as young children and the elderly, who are especially sensitive to heat stress. Do pay attention to the physical intensity of the activity: a relaxed museum visit or a sensory art experience at your own pace is generally more suitable than an activity with a lot of physical exertion.
How can I be sure that an indoor venue actually has air conditioning and not just ventilation?
Check the attraction’s website or contact them directly by email or phone to ask about the climate system. Professional venues such as cinemas, museums, and specialised experience attractions often mention this explicitly, especially during warm periods. Also read recent reviews on Google or TripAdvisor, as visitors regularly mention whether a venue was pleasantly cool.
What are common mistakes when planning a day out during a heatwave?
The most common mistake is assuming that a ‘covered’ venue is automatically also cooled — a market tent or covered terrace offers no cooling, after all. People also underestimate how warm they can get during physical activities indoors. Plan your visit preferably early in the morning or later in the afternoon, avoid the peak between 12:00 and 15:00, and choose a venue with a rest area to recover in between.
Can I combine an indoor attraction with other activities on a hot day?
Yes, but plan this wisely. Combine an indoor attraction with other cooled destinations such as a restaurant, a shopping centre, or a cinema, and avoid long stretches of walking outside during the hottest hours. Drive or cycle to your destination early, spend the midday hours indoors, and plan any outdoor activities for the early morning or evening when the temperature is more comfortable.
What if I feel unwell during an indoor activity due to the heat?
Notify the venue’s staff immediately — professional attractions have protocols for such situations and can guide you to a cool space. Drink water immediately, sit down, and cool your wrists and neck with cold water. If you do not feel better after a few minutes, seek medical help. Prevent this by hydrating sufficiently beforehand and not eating a heavy meal just before a physically active indoor experience.
