Once your horse has mastered the skills of allowing you to touch him from any side, will tolerate being tied and will allow himself to be lead into a trailer with ease, your horse is ready to conquer some more advanced training skills.
One of the skills your horse should have when he is learning advanced basics is to allow himself to be led around obstacles in his pen. Since he already trusts you to lead him, you simply need to help him to understand the obstacles will not hurt him. Allow him to sniff and even taste them if necessary. This will allow your horse to realize that you are never going to let anything harm him and he will figure out quickly he is supposed to go around the obstacles. Practice leading him around common obstacles he will encounter frequently when you're riding such as bushes, fences, trees and logs. Get him used to going around and patiently stepping over logs and branches in his path.
Another part of advanced training is to get your horse to learn to stand calmly when he is being groomed or bathed. Most horses love a bath but get very excited when having one. You need to teach him to learn to enjoy a bath and you can either distract him with soothing talking and always praise your horse when he is cooperative.
Spend time going over both basic training and advanced training items, horses need to be refreshed on what they have learned. Even if you're not taking your horse anywhere, periodically take him into a trailer so when it is time to travel with your horse it won't be an issue for him.
