The Greener Guide to Seeing Cornwall More Sustainably

If anywhere is going to increase your respect for the natural world, it’s the Eden Project. Sure, the otherworldly domes are cool, but the real magic of this landmark sustainable site – founded by Sir Tim Smit on the scarred remains of an old clay pit – is all Mother Nature. Traverse jungle-shrouded bridges in search of waterfalls in the Rainforest Biome, or explore wildflower meadows in the sculpture-dotted outdoor garden, marvelling at our ability to restore biodiversity when we put our minds to it. In keeping with the project’s mission, there’s a sunflower-shaped solar roof, toilets are flushed with rainwater, and food waste from the cafes is turned into fertiliser.

Like the thought of off-grid living? Be inspired with a stay at this zero-carbon eco-retreat, set in mixed pasture and woodland on the Fowey Estuary. The solar-powered bed and breakfast is energy-efficient (thanks to LED lights, triple glazing and wool insulation) and strives to put nature first, with an earthen roof and minimal landscaping of the 12-acre (5ha) grounds. It’s proof that sustainability can be stylish, with four river-view rooms featuring Weaver Green blankets and rugs made from recycled plastic, plus a kitchen stocked with charity shop crockery. Cycling and walking routes are encouraged, and outdoor activities are on the doorstep.

Think veganism, think rabbit food? This Truro cafe will change your mind. They specialise in meat- and dairy-free comfort food – exemplified by the Canadian poutine with cashew cheese and moreish vegan gravy – as well as excellent plant-based cakes. On sunny days, you can’t beat an afternoon on the whitewashed Mediterranean-style patio with a pint of Cornish IPA and a portion of “f’sh” (cider-battered banana blossom) and chips.

Eco credentials are worth the effort for the staff of the Greenbank. The team at Falmouth’s oldest hotel have been working hard to improve their recycling methods, lower their water consumption and save energy – so you can focus on chilling out on the terrace and enjoying spectacular views of Falmouth Harbour. They also host a biannual beach clean in collaboration with Surfers Against Sewage, which guests are welcome to join.

Left to ruin after World War I until 1990, this 200-acre (81ha) estate has been lovingly restored by Tim Smit and John Willis (a descendant of the original estate-owning Tremayne family). Today there is plenty to explore, including ancient woodlands, camellia-filled gardens and the UK’s only jungle. Oodles of organic fruit and veg are grown on-site for the public cafe, which is good news if you’re trying to follow a light-touch local diet: at Heligan the produce travels only 157yd (143m) from plot to pot. Green-fingered guests can also buy heritage Heligan seeds in the gift shop.

Cornwall has no shortage of outstanding beaches, with some more crowded than others (try them out of season if you can). Perranporth has a broad, three-mile (5km) stretch of sand suited for everyone from dog walkers and rock-pooling toddlers to wannabe surfers. For a real back-to-nature journey, walk to the beach from Newquay – a distance of 12 miles (20km) – along the scenery-studded South West Coast Path.

St Michael’s is a large seaside resort, but they’ve paid attention to little details in order to keep things green. Beyond the usual nudge to skip the daily fresh towels, there’s a display promoting sustainable things to do in Falmouth and beyond, while the fish served in the restaurant is also sustainably sourced (plant-based diners are well catered for, too). Blue Flag-bearing Gyllyngvase Beach – recommended by the Foundation for Environmental Education for its water quality and safety – is just across the road, ideal for a sunset dip.
