Fullpage.js provides you a few methods (see them in action here)

Two of these methods will help you to move to specific sections or slides in your website:

You can set one of this method to a button or use the fullpage.js callbacks to fire it when you desire.

In order to skip sections we can use the moveTo method in the onLeave callback. Here's a codepen.

And here's the relevant code:

new fullpage('#fullpage', {
    sectionsColor: ['yellow', 'green', 'purple', 'orange'],

    onLeave: function(origin, destination, direction) {
    	skipPages(origin, destination, direction)

function skipPages(origin, destination, direction){
        if(direction === 'down'){
            destinationIndex = destination.index + 2;
            destinationIndex = destination.index;


In order to make it work for us we would have to add the class name skip on the sections that we want to skip. 

For example:

<div id="fullpage">
    <div class="section">Section 1 </div>
    <div class="section skip">Section 2 </div>
    <div class="section">Section 3 </div>
