The best way will depend on your needs.

In addition to the form presented by Mauro, you can use only html pointing the href of the link to the page stretch that is at the top: 

<span id='topo'></span>

<p>
  bla bla <br> bla bla <br> bla bla <br> 
  bla bla <br> bla bla <br> bla bla <br>
  bla bla <br> bla bla <br> bla bla <br>
  bla bla <br> bla bla <br> bla bla <br>
  bla bla <br> bla bla <br> bla bla <br>
  bla bla <br> bla bla <br> bla bla <br>
  bla bla <br> bla bla <br> bla bla <br>
  bla bla <br> bla bla <br> bla bla <br>
  bla bla <br> bla bla <br> bla bla <br>
  bla bla <br> bla bla <br> bla bla <br>
  bla bla <br> bla bla <br> bla bla <br>
  bla bla <br> bla bla <br> bla bla <br>
  bla bla <br> bla bla <br> bla bla <br>
</p>

<a href='#topo'>Voltar ao topo</a>

Using Jquery 

//scroll normal
$('html,body').scrollTop(0);

//scroll suave
$('html, body').animate({scrollTop:0}, 'slow'); //slow, medium, fast

Using Javascript 

var scrollTop = function() {
    window.scrollTo(0, 0);
};
