According to data collected by the National Park Service Visitor Use Statistics website, Grand Teton National Park recorded the highest number of visitors in the last 36 years in 2014. During this past year 2,791,393 people visited the park, compared to 2,688,794 in 2013, an increase of 3.8%. Although the highest in the last 36 years, this past years' figure is still well below the record that was set in 1970, when 3,352,500 people visited the park.
Below a graphical look at visitation counts since Grand Teton became a national park. Curiously, the park experienced a massive slump in the 1980s - unlike any of the other parks I track. If anyone has any insight as to why, or what happened during that time period, please feel free to leave a comment.
