Great Cornish Gardens

Cornwall enjoys some glorious gardens and there are over seventy you could visit! The warm gulf stream and mild climate create growing conditions which support many sub-tropical, exotic and rare species not found elsewhere in the British Isles. The following are a selection of some of Cornwall’s unique and magical award-winning gardens.

Eden Project

One of Cornwall’s most iconic landmarks, the Eden Project is a truly memorable experience in an epic location. Consistently voted one of the UK’s best attractions, it is both an educational resource and an environmental showcase demonstrating in a vibrant manner how plants and people depend on each other for mutual survival on our planet.

Acres of flowers and herb-scented pathways wind down to two giant biomes supporting the world’s largest indoor rainforest. Rising out of the earth in what was a disused china clay pit and filled with plants from around the globe, the Eden Project aims to inspire and educate.

Opening Times

Usually, open every day except Christmas day.

The last tickets sold half an hour before the biomes close. Please check opening times before your visit as biomes may close early to maintain the health of plants.

Year-round activities, a shop and cafés serving tasty wholesome food from around the world, offer a full day out for all.

The Rainforest Biome

The first thing you will notice here is the humidity – you really are in the rainforest! Towering trees and lush tropical plants line the pathways as you wind around all four of the world’s rainforest environments: the Tropical Islands, Southeast Asia, West Africa and Tropical South America.

Discover the story behind cocoa, and see what it would be like to live in a Malaysian hut and work in the paddy fields. Look out for roul-roul partridges and Sulawesi white-eye birds on the way. There’s even a waterfall! Venture up the Canopy Walkway to the topmost platform and you’ll even discover what being at the top of a rainforest is really like.

The Mediterranean Biome

Representing the climate found in the Mediterranean, South Africa and California; pathways are filled with over 1000 plants including citrus fruit, herbs, olives and colourful flowers. Intertwining cork sculptures and natural scents feed the senses whilst giant aloe vera plants amaze. Each day, the Eden Storytellers are situated here bringing tales and songs to life. Once you’ve discovered everything you may want to enjoy some food in the Eden Kitchens, situated linking the Mediterranean and Rainforest biomes.

The Gardens

Eden is equivalent to the size of 30 football pitches and makes use of its outdoor space to grow flowers and plants which help produce fuel, and are medicinal or useful in some way.

Colourful borders lead to play areas, cafés and a stage. In the winter months, an indoor ice rink is situated in the centre and there’s a year-round zip wire (the longest in Britain), and a giant swing (payable separately)!

The Core

Press buttons, wind handles or make a dispersing seed pod to find out about energy, recycling and ecosystems amongst other things.

Housed in a carefully designed building, made to resemble the layers of a sunflower, there are also play areas and crafts.
