There are lots of animals to see up close, including lambs (of course) and piglets.
If it's wet there's a 'soft play barn' with the usual ball pits and 3 great slides - a gentle (but surprisingly fast) one and two 'freefall' slides for more adventurous kids.
Outside there are go karts and the enormous bouncing pillows.
For older children try Battlefield Live - for kids (and parents) over 8 years old.
The Big Sheep also has a sister attraction, just up the road, called South West Extreme, where you can try mountain boarding and climbing.
The Big Sheep is a working farm, and there are shows throughout the day (when the presenter said the show about rams was going to last 45 mins my heart sank - but it was actually entertaining and informative).
And of course there's always the brewery, and shop, to visit. Plus there's free wifi if you need to stay in touch.
If you're holidaying with your dog, you might want to take advantage of the free kennel facilities (first come first served) - there's also shaded parking and a large dog walking area.
So all in all, it's not quite the major theme parks, but then you shouldn't have to spend half your day queuing either.
Getting there
The Big Sheep is about 22 miles from the cottage and lodges, or about 40 mins drive. It's easy to find, on the A39, 2 mins west of the new Bideford Bridge. It's well signed (ex39 5ap) if you're using SatNav.
The main season runs from the end of March to the end of October. In the winter it's open weekends and school holidays - check their website for details.
