AngularJS template can only see what is available in a scope so you will need somehow to put $location service in a scope. There is one scope that is always available in AngularJS application called $rootScope so it could be use for your use-case.
What you could do is to use run() method of a module to expose $location in the $rootScope:
var myApp = angular.module('myApp', []).run(function($rootScope, $location) {
$rootScope.location = $location;
});
this would make 'location' available in all templates so later on you could do in your template:
Current path: {{location.path()}}
