There are several associations that serve the needs of blind and visually impaired people. Some of them sponsor competitions, or form local clubs, or offer training in sports including skiing, swimming, football, sailing, hiking, golf, archery, and just about any sport of interest to you.

These associations also have information on how equipment can be adapted for low vision or blindness, and tips on safe practices.
