It's to cold so no one has visited Neptune.
It's to far from the sun.
No human being has ever visited ANY planet not event Mars. The time taken for the journey would be so high that we do not have the present technology to support it (even a journey to Mars would take about 7 months which is too much to keep foods, oxygen and other materials for just a single person). Then there is of course the question of cold.
