The Eden Project sits in a vast former china clay pit a few miles from St Austell, and from the moment you see the white, bubble-like biomes glittering at the bottom of the hollow it is clear why this is Cornwall's best-known attraction. The site opened in 2001 and turned an industrial scar into a living showcase of plants from around the planet. The Rainforest Biome is one of the largest indoor rainforests anywhere, a hot, humid world of towering trees, waterfalls and a canopy walkway where you climb up through tropical fruit, rubber and cocoa plants. Next door the Mediterranean Biome is drier and gentler, with olive groves, vines, citrus and the scents of southern Europe, while the outdoor gardens hold the temperate plants of Cornwall itself, from tea and hops to sunflowers and wheat. The idea behind Eden is that people and plants depend on each other, and the displays tell that story without feeling like a lecture. Sculptures, interactive exhibits and a large indoor hall called the Core explain how food, medicine, fabric and fuel start life as plants. There is also a full programme of seasonal events, and in summer the pit becomes a concert venue with a stage set against the biomes. Kitchens and cafes on site serve food built around plant-based and local produce, which suits a venue with this theme.
Why visit
Eden works for almost every kind of group. Children enjoy the humid heat, the noise of the rainforest and the chance to run around outdoors, while adults get serious horticulture and a genuinely memorable landscape. It is also one of the easiest big attractions to do in poor weather, because the two biomes and the Core give you hours of cover. If you only have time for one major paid sight on a Cornwall visit, this is the one most first-timers choose.
What to see
Begin in the Rainforest Biome while you are fresh, because the heat builds, then take the walkway to the top for the view over the canopy. After that drop into the Mediterranean Biome, and finish with the outdoor gardens and the Core. A good visit takes most of a day, and more if you add the high-adrenaline activities that run at the site. Allow time for the long downhill and uphill walk between the entrance and the biomes; there is a land train for people who prefer not to walk the slope.
Planning
Tickets are normally timed or dated, and the site is busiest in school holidays and on summer weekends, so book ahead and arrive early. Travel light because the rainforest is hot, and wear layers that come off easily. The site is reached by car, by bus from St Austell, or by the cycle and walking route from the nearby railway station at Par, which is a pleasant alternative to the car park queue. Dogs, mobility access and opening times vary through the year, so check before you travel.

Good questions
Is the Eden Project indoors or outdoors?+
Both. The two biomes are indoors and climate-controlled, and the gardens, trails and viewpoints are outdoors, so bring weatherproof clothing as well as light layers.
How long do I need at the Eden Project?+
Plan on four to six hours. Families with young children often stay longer, and a day with an adventure activity can run to a full day.
Is it easy to get to without a car?+
Yes. Buses run from St Austell, and there is a walking and cycling route from Par station, so a car is helpful but not essential.
Is it suitable for wheelchairs and pushchairs?+
Much of the site is accessible, but the pit is steep. A land train and accessible routes are provided, so check the venue before you go.
Can I visit in winter?+
Yes. The biomes stay warm all year, which makes winter a good time to visit, though some outdoor features and events are seasonal.
