Cornwall has over 400 accessible beaches, 290 miles of coastline and at least 10 large lakes or reservoirs; there is so much to explore!
Siblyback Lake is a reservoir that was completed in 1969, its primary use was to provide drinking water but now it is also a great for recreation. From Hendrifton Farm you can walk to it in about 30 minutes, or drive to it in 5 minutes. Once there, you can walk, run and cycle around it, sail and kayak on it and if you fancy a bit of fly-fishing, you can do that too. Olive and Co café is great for refreshments.
For Wild Swimming you can head to Goldiggins Quarry, a not-so-secret spring-fed lake on Bodmin Moor. About 40 minutes walk from the Hurlers carpark or if you want to leave the car at home then it is about 3 miles to walk there from Hendrifton Farm. There's a smaller quarry on Caradon Hill too.
Beaches are in abundance, it just depends what you want to do! Rockpooling at Hannafore, just west of Looe; dog walking at Seaton and Downderry on the South Coast; surfing at Perranporth, Watergate Bay, Fistral and many others.
For some more relaxing beaches with less people, you could walk along the South West Coast Path from Looe to Portnadler Bay and on to Polperro (you could get a boat or bus back to Looe) or check out the National Trust beaches and coastal walks – Lantic Bay and Lansallos amongst others on the South Coast.
Out on the water
If you want to be out on the water there's Looe self drive boat hire, and also in Looe, E-Foil Cornwall where you can hire a paddleboard or learn to fly above the water on an E-Foil! Padstow Sealife Safaris offer boat trips of one and two hours duration and the Polperro Boat Men operate various trips out of Polperro on a daily basis.
On the North Coast, from Newquay to Bude, Cornish Rock Tors offer Coasteering, Sea Kayaking and Paddleboarding.
