ATV trail riding is a great way to spend an afternoon with your friends. Trail riding is a great way to promote camaraderie amongst your friends and it is not difficult but it does require that you use your common sense.
If the ATV trail says it is difficult and your experience riding ATVs isn't that high. Don't ride that trail. You won't want to learn those kind of handling skills on the fly. It's not a safe way to learn climbing and
Another consideration when trail riding on your ATV is respect for the environment. Don't do anything that will harm the terrain. Stay on the designated ATV trails and don't go trail blazing.
Crossing obstacles is a common occurrence on your ATV and to cross them you can almost always use the same technique. Approach them straight on and approach the obstacle very slowly. This holds true for downed trees as well as some stair step hill climbing. Give a little throttle and you should be fine, be careful not to give too much or you might cause your front end to jump up.
Always climb hills straight up and straight down, never at an angle. Your ATV can tumble with you on it if you go at an angle and it is not safe for you to traverse hills in this manner.
Other good practices include riding responsibly and if you find trash out on the trail, pick it up and pack it out. Even if it not yours. It will help maintain the trails for the next ATV rider.
