Woburn Safari Park, Beds.

The main attraction is a drive-through, which takes you through several areas of parkland in which large animals roam. Here are areas with herbivores, including giraffes and elephants, carrnivores and monkeys. There is also an on-foot area, with restaurants etc, and displays of smaller and more child-friendly animals.
I took my elderly mother here in 2008 and remember herds of grass-eaters of various species on
the wide grasslands, a large and obviously male elephant, a wood with various species of monkey monkeying about, and a lot of lazy-looking lions and tigers lying about in groups. It took over an hour to drive through all the enclosures.
The tickets are quite expensive, but unless wild animals really bore you, you should find that it’s worth the investment. Season tickets and discounts are available.
Be aware that convertible cars are not permitted in the carnivore enclosure 🙂 and that in the monkey enclosure, monkeys may damage parts of your car. You can drive around the enclosures loop as often as you like.
