Alnwick Garden attractions and experiences

The Alnwick Garden in Alnwick, England, is one of the most extraordinary and innovative gardens in Britain and a highlight in the county of Northumberland. Located near the impressive Alnwick Castle, the garden was opened in 2001 and is the result of the visionary work of the Duchess of Northumberland, Jane Percy. With its creative water features, the infamous Poison Garden, and a mix of botanical diversity and art, it has become a popular destination for visitors seeking nature, history, and a unique experience. The garden covers approximately 17 hectares and combines traditional garden art with modern elements in a way that both entertains and inspires reflection.

Botanical diversity at Alnwick Garden

The history of the Alnwick Garden began in 1997 when Ralph Percy, the 12th Duke of Northumberland, and his wife Jane took over the estate. The original garden, designed in the 18th century by landscape architect Capability Brown, was at that time neglected and largely overgrown. The Duchess had the idea not only to restore the garden, but to transform it into something entirely new - a place that would inspire both the local community and international visitors. Supported by Belgian landscape designers Jacques and Peter Wirtz, the Alnwick Garden was gradually developed and expanded from 2001 onwards, with each element carefully planned to create a balance between aesthetics, education, and entertainment.

Poison Garden guided tours booking

One of the most striking features of the garden is the Grand Cascade, a monumental water feature that is considered the centerpiece of the site. This artificial waterfall, designed by Wirtz, consists of a series of steps over which water cascades in a dramatic display, accompanied by fountains that are activated at regular intervals. Children and adults alike are invited to paddle through the shallow pools, making the garden an interactive experience. The Grand Cascade is complemented by a network of other water features, including the "Serpent Garden" fountains, which fascinate with their spiral patterns and often surprise visitors with unexpected splashes.

Another highlight is the Poison Garden, a restricted area that houses only toxic plants and is accessible only through guided tours. This "poison garden" was inspired by the Duchess, who wanted to show a darker, educational side of botany. Here grow over 100 species, including deadly plants such as belladonna, hemlock, and castor bean, as well as lesser-known, dangerous plants like the angel's trumpet. The plants are hidden behind black grids and warning signs, and the tours not only explain their toxic properties, but also their historical use in medicine, murder, and mythology. The Poison Garden has given the Alnwick Garden international renown and attracts visitors curious about this unusual perspective.

Alnwick Garden restaurant recommendations

In addition to these attractions, the garden offers a variety of other areas. The Rose Garden houses over 3,000 roses in different varieties, whose scent fills the air in summer, while the Ornamental Garden, with its symmetrical beds and elaborate hedges, showcases a more classic style of garden art. The Bamboo Labyrinth invites visitors to get lost in a maze of tall bamboo stalks, adding a playful element. For children, there is the "Treehouse," one of the largest treehouses in the world, connected with rope bridges, platforms, and a restaurant - an architectural wonder in wood that stimulates the imagination.

The Alnwick Garden also has a social mission. The Duchess founded the charity The Alnwick Garden Trust, which focuses on helping disadvantaged communities, such as through programs for the elderly or for youth with drug problems. The garden partially finances itself and supports these initiatives, giving it a deeper meaning. It also plays a role in environmental conservation, with sustainable practices such as rainwater harvesting and promoting biodiversity.

Culinarily, the garden offers several options. The "Treehouse Restaurant" serves upscale dishes in a unique wooden setting, while the "Potting Shed Café" offers lighter meals and snacks, often with ingredients sourced locally. Seasonal events such as the "Winter Light" festival, where the garden is illuminated with lights and installations, or summer concerts make it attractive all year round.

A good place but disappointing early season ( I went in first week of March) there is very little winter interest planting - many bare tree and bare ground- no winter shrubs. Even the poison garden was farcical as the guide pointed to bare ground and talked of nettles not yet visible, and to empty cages showing us pictures of what could be there. Some evergreens were present but no mention even of yew or the stories of the poisoners depicted on the walls. Surely a seasonal script could be prepared to make the most of the experience before the plants emerge. Fountains fantastic.

Despite our visit being in early March, and not much colour in the garden, we had a great visit. The poison garden tour, led by Barbara, was informative, a little gruesome and a lot of fun. We enjoyed the adult swings in amongst the cherry orchard, watched the fountains in the cascade and had a fab afternoon tea in the pavilion. A thoroughly enjoyable day.

Loved it. Can’t believe its taken all these years to come to Alnwick Gardens. Beautiful- cant wait to see it in bloom. Only thing that lets down the gardens is the cafe. It isnt to a high standard as you would expect. The cheese scones were raw, the entire batch shouldn’t of been brought into the cafe for sale. The jacket potatoes were put on the BIGGEST plates which meant the potatoes were rolling around! They came with with a few leaves leaves- definitely not a salad garnish as advertised. It looked pitiful. Brownies were stale and dry. And finally, due to my daughter having an intolerance i asked if she could have a pizza minus the tomato base. Chef said, no can do as the bases come already with sauce on?!! So obviously not freshly made like advertised. At the impeccable high standard of the gardens, you’d expect alot more from the cafe. It was disappointing. It wont stop us from returning to the gardens but we will be making other arrangements for lunch.

A bit of a mixed review but overall a positive experience. Firstly the negative - the roll and sausage I received (along with a coffee) was absolutely woeful for £5.50 or was it £5.95? Not even any butter on the roll. You can do better Alnwick Gardens! Now to the positive - even on a cold February day the gardens were wonderful and well worth a visit. Particular praise must go to John Knox (I think that was his name) who was in the Poison Garden on 14th Feb who was absolutely brilliant - enthusiasm, fun and informative in equal measure and a great asset to the gardens.

Pros: Relaxing cherry orchard with bench swings Fun fountains area Beautiful formal garden Cons: Poison Garden is disappointing Café food is incredibly unsatisfying Visited for The Poison Garden but honestly that was underwhelming; much smaller than expected, crowded guided tours that are first come first serve (20 people at a time), serial killer info painted on the back wall which just felt tacky and insensitive - why not the history of the plants? There's a single bench at the far end so if you can't stand for long, bring a folding chair. Honestly though, if you find poisonous plants interesting, you'd be better off reading a book or doing a Wikipedia deep dive. However - there's a lovely area beyond that, the cherry tree orchard, which is full of swinging benches in dappled shade to relax on. I imagine in spring when the trees are in blossom it's spectacular. On the hot summer day we went, the shade was wonderful. Very calming. The water fountain/sculptures area is really fun, it smells like the water is chlorinated so safe for kids to play in. Really fun if you like sensory play with water, even just visually if you don't want to get wet. The formal gardens at the top of the hill is very nicely kept, lots of little nooks and benches to rest in, several of which are shaded. A beautiful spot. The café is okay for a quick drink and cake, but avoid the actual food - it's expensive, meanly portioned, and exceedingly bland. We wished we'd brought our own. What we actually visited for was disappointing, but we still had a good day. It helps that we got in with the Gardener's World 2 for 1 ticket offer, so we paid half the price. Not somewhere I'd visit again, but if you have children, it'd be a good place to for them to let off steam. Just carefully steer them through the large gift shop - it is very well stocked with kids goodies they'll have forgotten about in a week's time.

Alnwick Garden is truly wonderful! It's a little frustrating to be guided through the gift shops, but I'm sure that's important to help cover costs of the outstanding grounds.

We visited Alnwick Gardens today, being mid winter most of the plants had died back and there wasn’t a huge amount of greenery. However we still really enjoyed the visit and would highly recommend visiting. We had the tour of the poisonous plants garden, it’s was very interesting and the guide lady was very knowledgeable about poisonous plants in general. We’ll definitely be returning in the spring/summer with the kids, as the entry ticket included entry to Lilidorie too.
