Authentic Finnish Mökki Culture & Off-Grid Camping in West Sussex
It started with a long-held dream: to build a low-impact, eco-friendly pop-up campsite rooted in traditional Finnish mökki culture. Today, we open our gates for just 13 weekends every summer season to invite you into our quiet corner of the Sussex countryside.
In Finland, mökki life is all about slowing down, leaving everyday stresses behind, and embracing simple living close to nature. Whether you’re a first-time camper, a solo traveller, or gathering with friends, Sunnyside is your space to disconnect, recharge, and find community.

For the rest of the year, we manage the site as a hay meadow to improve biodiversity and provide for local walkers.
Our Nordic spirit
Our Nordic spirit
Sunnyside founder Katja is a proud Finn. Finland is officially the happiest country in the world and Kat knows why. "Our happiness comes from many things but, if you ask me, our ability to integrate nature into our lives is top of the list. In Finland, the nature isn't just around us, it's within us. Being outdoorsy isn't just a trait, it's a way of life."
Suomi sauna
Suomi sauna
At Sunnyside, we light our Finnish wood heated sauna. We offer £5 per weekend wristbands, you can use it during your stay. In a sauna, people cleanse their bodies and minds and embrace a sense of inner peace. That's why the Finns call the sauna a ‘church of nature’. All you need is a towel and your authentic self. We think its the Most finnish sauna within an hour of london
Firepits for all

We love campfires and see them as an integral part of the camping experience. Campfires bring people together at the end of the day, to cook, socialise and relax. The smell of the wood smoke at twilight and the excitement on the kids' faces when the marshmallows come out are bound to set you up for a perfect night away from Londons city lights!
Foodie Fridays
Foodie Fridays
Our new adventure for this year is Foodie Fridays!
As you all might know, we are foodies and love cooking and eating! We have experimented catering ourselves, but realised quite quickly that is not for us.
We have a few communal foodie weekends, please check our dates & events for more info!
Food trucks at Sunnyside have been such a sucess that we have chosen work with food vendors on both Friday and Saturday nights.
Check out our social media to see who will be serving on your stay.

I have seen headlines talking about a “loneliness epidemic” facing the UK. With roughly 3.8 million people experiencing chronic loneliness, it’s clear that many of us never fully recovered from the isolation of the past few years. I don’t think there is an simple solution for such a complicated issue. But sometimes, the best place to start is with the basics: getting off our screens, stepping out of the house and reconnecting with the earth and each other.
At Sunnyside, we’ve built a space designed for exactly that. We provide lots of activities free and open for everyone, have a communal fire that anyone is welcome to sit around & chat and our communal sauna is a joy.
We don’t claim to solve the loneliness crisis by any means! But we do offer a place for connection with nature, ourselves and others.
If you are looking for a break in a friendly environment, our gates are open!

Those of you who visited us last summer may have been lucky enough to have already met the lovely Kilted Cocktails!
We feel very privileged to have them onboard: It feels very luxurious to finish the day sitting around the campfire with a delicious cocktail or mocktail in your hand, served with a friendly smile!
We are so pleased to announce that they are coming back this summer they have lots of lovely recipes in store to complement some of the activities we have on offer.
Come and say hello and join us for a Campsite Cocktail hour!
It's oh-so-easy to get to Sunnyside pop-up camping! We are just over an hour's drive away from central London and only 5 minutes in a taxi from East Grinstead rail station.

What our customers Say

It's wholesome, low-key, and super friendly. The atmosphere felt genuinely safe, which meant I could let my 7-year-old roam freely - and that's all he really wants!
I didn't try the sauna this time, but friends who did said it was fantastic.
The owners were incredibly friendly, and it's the kind of place I'd happily return to on my own with my son - I know we'd both enjoy it, and there would be other lovely adults around to chat to. A really special spot.

All of it was really well put together, and I think there's something here for all types of campers. There's four fields, so if you want remote 'wild' feel camping, you can get that there. Then the community feel of the first field is unlike any sites I've been to; Heath and Kat were so welcoming, friendly and down to earth.
Lovely woods and trails for walking surrounding the area. Facilities are pretty great too, had a lovely sauna with my 7 year old there's a little wooded area round the central camp and rope ladders, hammock swing etc. It's my little boys new favourite camp site!
