If you are new to Wikipedia and just want to explore, or if you don't know where you want to go, the Simple English Wikipedia has a random page feature that takes you to any one of the pages on this wiki. In most cases, you would want to see any article. This is easily done by going to the Special:Random page, which you can find on the left side of the page, under the Wikipedia logo, which says Show any page. Once you click this link, you will be taken directly to a random article page without having to do anything else. Another link you can use is Special:Randompage, which works in the same way as Special:Random.
Sometimes, you may want to go to a random talk page, user page, or MediaWiki page. Wikipedia lets you do this, too. Just add the type of page you want to see after Special:Random, with a slash in between. For example, Special:Random/Help will take you to a random page in the Help namespace; Special:Random/Category will show the contents of a random category, and so on.
The pages you visit using this feature isn't stored in your browser's back-button stack. So, if you hit back after multiple clicks of the feature, you will go back to the page you where on when you first clicked it.
