iOS 7: Limit access to specific websites

Restrictions websites iOS 7For the parents in the audience, iOS 7 gained a major new Restrictions option in Settings > General > Restrictions > Allowed Content > Websites. Along with existing control over specific apps, content ratings, and other options, you can now limit a device to specific websites you add to this area. Tap the Edit button in the upper right, then scroll to the bottom of the default sites Apple listed to add your own.
