Children’s party

Are you a young professional parent and your life is full of work and more? No time to organize a children’s party for your son or daughter? Fed up with all those screaming children in your house? With my children’s parties out in the dunes your children will be able to explore new situations and experience new things they mostly never did before. And I will make you enjoy your child again! Let’s make a party what it really should be: a joyful event for you ánd your child!

Children’s party in the dunes: all children love to go on an exciting hike outside in the dunes with their friends!
There is always something to see or to explore. Let them experience what they can do in nature! For example my hike with GPS, the knightly quest, exploring bunkers in the Amsterdam Watersupply Dunes, dropping with GPS, party on the beach, a hike in the dark, eating from the wild and a lot more. Also for adolescents! The possibilities are endless. And while they play, they learn that spiders do not bite, that deer won’t attack, that not all fungi are toxic, that a wood in the dark is scary but not dangerous, and a lot more! Often I get as feed back from children that this was ‘the coolest party ever’! Cool, instructive and boudary breaking. And as parent you do’nt need to organize much, ideal when you are busy! And no, it is NOT dangerous outside, if you only apply some basic precautions. Download here my FREE ADVICE for visiting the dunes safely (TIPS om veilig de duinen in te gaan; in Dutch only) and a flyer where you can find all about ticks: Teken en Lyme Folder RIVM apr2016 (in Dutch only).

How does it work?

For all hikes applies: it takes 2 hours (sometimes a little more); maximum of 12 children (in some cases this could be more, but only in contact). Date, starting time and place to start to be determined together with you. Depending on age of the children parents join with zero, one or two adults. I will always accompany the group, and the group will stay together. All childen on the hike are insured for injuries. NB. I am experienced in dealing with children with autistic features, please discuss the possibilities with me. Ask non-commital more information. Catering: if you want you can book a picknick in the field (I will cater), or give some food to all the children by yourself, or you can organize something to eat in a neighbouring restaurant as to conclude the children’s party, for example with pancakes.


All hikes in Zuid-Kennemerland: € 149,- incl. BTW for a group up till and including 8 children, duration 2 hours. More than 8 children? Then there will be extra costs of € 10 per child. Picknick: € 5 per child. Mini campfire to conclude the hike in Middenduin: € 30,- extra. Hike in The Hague? Then I have to charge € 50,- extra for costs and time for transport.


Children who join me are insured to injuries. Nevertheless I would like it that parents join me (especially with younger children), so there will be ‘more eyes’ and so we can jointly decide what is OK for the children.
High risk activitities (like campfire and climbing trees) only in consultancy with you as parents. Older children like it when you will not join us! Everything to be decided by both of us, what is the best for your child!
In case of bad weather or unforseen odds you are allowed to cancel the activity without costs, or you can postpone it. When you cancel, you are responsible for an alternative yourself.
Just in case I become ill or other unforseen odds, I will try my best to find someone for replacement. If I don’t succeed, the hike will be cancelled.


Bomen klimmen!Climbing trees: very popular at all hikes and children’s party s!

Do you need consultancy about nature or ecology? You don’t know if there are any protected species to take into account? Maybe you need a quick scan, global research or detailed information before starting a project?  A survey? A practical advice about nature management (grazing, vegetation management, invasive species) or a management plan? Or do you need a review or second opinion on an existing ecological report?

My consultancy can offer it all. I will answer your questions about nature, law, protected species and more. Contact me now! You can find some of my reports under Projects (in Dutch).

About me

Who is Antje Ehrenburg?
I am born and raised in Friesland (1962) in the north of The Netherlands, and I am living in Haarlem since 1988. I did an applied study in population biology (ecology) at the Agricultural University in Wageningen (1980-1988) with grades in vegetation ecology, soil science, environmental sciences and license to teach biology on the highest level (first grade). After my studies I have worked as an ecologist / researcher / advicer / text editor at ‘Gemeentewaterleidingen Amsterdam’, the drinking water company of the city of Amsterdam, now called Waternet (1988-2011). I did research in the dunes, adviced about nature management, guided volunteers in monitoring and did the editing of a newsletter about nature. The Amsterdam Watersupply Dunes were – and still are – my field of work. In 2011 I started my own consultancy in ecological research and monitoring. My academic background and years of experience formed me to the versatile ecologist I am now.

About me: I am practical, positive critical, enthousiastic, listening, directed to solutions, linking, targeted, and always keeping in mind: man, nature, proces and language.

How I judge nature? Nature is green, blue, red and yellow, just like my logo. Dry, wet, complex, resilient and never the same. Nature is also magnificent, intriging, rare, difficult or expensive. In any case less simple than it seems. Nature does not reveal it’s secrets all at once. Nature also has a lot of interfaces with legal frameworks and society. That’s why you should take nature into account. If you want, I can help you with it. Another possibility: just enjoying nature by going outside! For example: book a excursion or children’s party with Antje Ehrenburg! (English or Dutch spoken).

I am also editing the nature magazines ‘DUIN’, ‘Fitis’ and ‘Tussen Duin en Dijk’. In 2003 I started the Historical Society Amsterdam Watersupply Dunes. In my freetime I like to roam into the dunes or hike on long distance pathes. I am also working as tourleader for SNP Natuurreizen (walking holidays with groups) in Europe since many years. On LinkedIn you can read more about my activities.

Besides all this I love choral singing and organizing. If you like, you can ask me for organizing choir projects and tailor-made choir tours in The Netherlands and abroad. Take a look on

I am also mother of two sons (1994, 1998).

You can reach Antje Ehrenburg on: info ed or on my mobile phone tel. +31-653361478 or via contact page.

When necessary I cooperate with other people, Ecokids and Natuur is een feest.
