If you travel in April, you can expect fantastic late-season conditions as well as empty slopes (the season normally spans from late November until the beginning of May). You should plan your trip between now and mid-May if you want to be able to ski during peak season (which is usually between early December and late March). The best months to go skiing are generally considered to be January through March. The weather is usually warm enough that you won't need a jacket, but it can get cold at night if there's snow on the ground. There may be some ice on the trails during these months if it has been freezing overnight. April is too late in the season to be able to enjoy skiing and riding, but if you do decide to go, you'll find plenty of good deals if you book ahead of time. There are two types of terrain at most resorts: beginner and advanced. Beginner areas have lower jumps, less steep hills, and fewer obstacles than advanced ones. Most people start out on the bunny slopes, which are perfect for learning how to control your speed while avoiding crashing into anything in front of you. As you gain experience, you can move up to more challenging slopes.
