Eden Project

For the first few months of construction in 1998, it rained every day at the Bodelva china clay pit near St Austell. Forty-three million litres of water poured into a 60-metre-deep hole in the ground that had been mined for over 160 years and was sitting 15 metres below the water table. The engineering team improvised a drainage system and kept building. When Eden Project opened in 2001, it had used 230 miles of scaffolding during construction, enough to earn a Guinness World Record. It cost £141 million, funded through National Lottery grants, Millennium Commission money, and European regeneration funds. The exhausted clay pit is now the site of the world’s largest indoor rainforest.

That origin story matters. The Eden Project was not built in a pleasant rural setting. It was built in a hole, on terrain that had been stripped of soil, on land nobody else wanted. Over 83,000 tonnes of soil were manufactured for the site, using composted bark and mineral waste from nearby mines, in collaboration with researchers from Reading University. The entire project is, in that sense, a demonstration of what environmental regeneration looks like in practice.

The Biomes

The Rainforest Biome is the centrepiece: a geodesic dome enclosing 1.56 hectares of tropical plants at a maintained temperature that can reach 35 degrees Celsius in summer. The structure’s ETFE (ethylene tetrafluoroethylene) plastic cushions transmit more ultraviolet light than glass, which is what makes growing tropical species viable in Cornwall. Inside, the planting covers crops, medicinal plants, and timber species from rainforest regions across the world. A canopy walkway lets you look down into the understorey.

The Mediterranean Biome is the cooler of the two enclosed structures, representing the climate zones of the Mediterranean basin, South Africa’s Western Cape, and California. Olive trees, citrus, lavender, and grapevines are among the species represented. It is quieter than the Rainforest Biome and often rushed through by visitors, which means you can look around it properly if you leave the crowds behind.

The outdoor gardens surrounding both biomes change through the seasons and are worth walking thoroughly rather than cutting across on the way to the next dome. The Core, the on-site education and exhibition building, has interactive exhibits on sustainability and natural systems.

Tickets and Getting There

Adult tickets booked in advance cost from £35.50. Booking ahead is essential: on the busiest school-holiday days, on-the-day admission is not guaranteed and advance booking is mandatory. Under-5s enter free. Between late June and early September 2026, a government VAT reduction scheme is reducing prices somewhat, so check the Eden Project website for the current rate before you book.

The site is in Bodelva, roughly three miles northeast of St Austell. From London Paddington, trains to St Austell take just over five hours on the mainline to Penzance; from there the Shuttle Bus (Stagecoach T1) runs to the Eden Project entrance. By car, the A391 from the A30 at Innis Downs takes you directly. Newquay Airport is about 30 minutes away and is served by flights from several UK cities and some seasonal European routes.

Arrive when the site opens. The main biomes draw crowds from mid-morning onwards on summer weekdays and are very busy on school-holiday weekends. The outdoor gardens at the eastern end of the site are often far quieter than the biomes, even at peak times.

Eden Sessions

From mid-June to mid-July, Eden Project runs Eden Sessions, a concert series held inside the pit after the daytime visitors have left. The 6,000-person capacity makes it an intimate setting by festival standards. The 2026 season ran through to July 11 and featured Pixies, Bastille, and Snow Patrol among others. Tickets are separate from daytime admission and sell out quickly. A shuttle bus runs between St Austell train and bus station and the venue before and after each session.

Where to Eat

The on-site food offer includes the Eden Bakery for Cornish pasties and sandwiches, and the Mediterranean-inspired restaurant inside the Med Biome for hot meals. Food at both is decent for a major attraction, though not destination dining. The quality and variety improve if you walk to the smaller cafes scattered through the outdoor gardens. Prices are in line with what you would expect at a large UK visitor attraction.

Where to Stay

St Austell has budget-friendly options including Premier Inn and Travelodge branches, both around ten minutes from the site. The Britannia Inn is a local pub with rooms a short drive from the entrance and is well-reviewed for proximity. For more character, Mevagissey is seven miles south: a working fishing village with independent B&Bs and guesthouses at various price points, and considerably more atmosphere than central St Austell.

The wider area has self-catering cottages in the farmland and coves between St Austell and Fowey, which is a good base if you are combining Eden with the coastal Path and the Lost Gardens of Heligan nearby.

Beyond Eden

The Lost Gardens of Heligan, about five miles south of St Austell near Mevagissey, are the most obvious companion visit. The gardens were abandoned during the First World War and their restoration from 1990 onwards is the story that directly inspired Tim Smit to create Eden. The two sites are run by different organisations but are often paired on multi-day itineraries in Cornwall.

The Cornish Mining World Heritage Site and several of the coastal tin and copper mining landscapes to the west are less visited than either Eden or Heligan and give useful context for the industrial history of the region that shaped both the china clay industry and the quarry Eden now occupies.

Practical Tips

The zip wire at Eden is a crowd-pleaser but has its own booking queue; reserving a slot online in advance of your visit saves time on the day. The site has extensive parking with a charge; the shuttle bus from St Austell is easier if you are arriving by train. Dogs are permitted in the outdoor gardens but not inside the biomes. The site is fully accessible with good pathways throughout, though some of the steeper garden sections require effort.

The site closes every year for a period in January and February for maintenance and staff training, and on Christmas Day. Check the website before travelling in winter months. The Eden Project app includes a site map and information on the plants inside the biomes, which is more useful than it sounds when you are standing in front of a 20-metre cacao tree trying to identify it.
