The Castle Garden

The Castle is - as far as we know - the only climbing gym with a garden.

Not only is this a vast quirky space to relax in during your visit, it hosts three outdoor boulders, has a plentitude of wildlife habitats for biodiversity, and provides food through it’s annual vegetable beds, herb terraces and orchard.

Wrapping around the site, the 1.5 acre space is there for you to visit whenever the Centre is open.

Get involved!

There is a dedicated experienced Garden Team, but the space would not flourish without our volunteers. If you would like some functional exercise, time outdoors being creative and getting mucky, and chance to meet new folk, we’d love to have you involved.

Volunteers earn a climbing credit and a small lunch for a full day working with us.

Volunteer days are Monday and Thursday each week, plus the last Saturday of each month. A full day is 11am - 4pm, though you are welcome to come along for an hour or so (without benefits!)

For more information, please download the ‘welcome pack’ document.

Volunteers are required to complete an induction prior to starting for health and safety purposes; please read and complete the ‘induction form’ then email it to garden@castle-climbing.co.uk

How to volunteer

Outdoor boulders

Climbing outdoors? Within the M25? Yep, we’ve got you covered. Within our leafy garden are three huge boulders with over 130 problems to work on. Open seasonally during Spring to Autumn.

About our garden

Building up from just four no-dig vegetable beds in early 2009 to the vast eclectic space you experience now, our Garden boasts many hidden pockets of delight — all serving an important function for us or for wildlife. Established from the beginning with permaculture design principles, the space allows us to mimic natural ecosystems in a way that is cooperative and resourceful, yet is ultimately self-sustaining through energy cycling. Importantly, though the Garden exists outside of The Castle walls, there is an innate connection between the inside and out; through the mental benefit to you our customers, passers by and local residents, and a physical benefit through our veg, fruit and herbs. 

We use organic methods to grow food and manage the site, which means no synthetic inputs, including pesticides, that would disrupt the entire ecosystem. Compost is produced on site solely from the Centre’s green and veg “waste”, and we even capture the humanure broken down in the compost toilet system for feeding the hedges. We have an affinity to repurposing materials — akin to repurposing a Victorian water pumping station for a climbing wall! Around the site you’ll see decommissioned climbing ropes woven as chairs and windbreaks, old pallets as planters and benches, and climbing holds as stools. We’re enthusiastic to nurture this harmonious and productive system not only for us directly within The Castle, but within the wider Borough of Hackney and outwards.

Visit to explore:

  • The annual no-dig vegetable beds where we grow hardy varieties year-round, including salad, kale, chard, beans, tomatoes, cucumbers, courgette, squash, leek, onions and corn
  • The forest garden with nuttery, orchard and wildlife pond, along with native herbaceous perennials used in our salad and teas
  • The herb terraces, where we grow both herbs for teas and balms, and flowers for cutting, dyeing and for pollinators
  • The sensory garden — otherwise known as Gerry’s Garden — where you can sit and look down upon the space or even do some acupressure on the climbing hold cobblestone
  • Various wildlife habitats dotted about (most of which are inconspicuous to avoid disturbance!), including a main biodiversity spot by the New River that was developed in partnership with the Forest Recycling Project, and living and dead hedges on the boundary edges
  • The apiary where we use natural beekeeping methods to nurture families of honeybees, along with solitary and bumble homes around the site
  • Glasshouse, polytunnel and cuttings trays where you can see propagation in action (you can even put your head in to analyse our sowing schedule and rotation plan!)
  • Our timber and cob roundhouse with green roof, and cob pizza oven
  • The south-facing Castle wall where we have fig, grape and kiwi
  • The rope swing underneath the majestic catalpa tree (and if you’re cheeky, maybe even a hammock between the tree and roundhouse) where parakeets will screech above you
  • More herbs, flowers, fruit trees, another green roof and even a mini Fontainebleau forest around by the outdoor boulders
  • A swale that acts as a self-sustaining terrace for fruit trees, irrigated by greywater from the showers
  • Miniplot allotment area cared for by local residents and staff
  • Platform seating area with benches where you may also find someone practicing yoga
  • Hidden away but worth a mention, water tanks inside the walls that hold rainwater collected from The Castle roofs
