Not an easy access, you would have to work out how to open this little problem first. Between the barbed wire, baler twine and fencing wire there are a few choices to work with.
Perhaps the only route to success would be to adopt the 'Alexander the Great' strategy and give one mighty blow with your sword but then you'd face the tricky problem of closing the gate again and the police would take a dim view of you wandering around with your short sword in your hand. Plus, and this is a big plus, I don't see me becoming the King of all Asia.
The solution is always to carry a pocket full of baler twine or just don't go in there in the first place. I bet Alexander the Great never thought of that, and the baler twine would have kept his trousers up too.
That's the countryside for you, really welcoming.
