There are no roads leading to the park and it is most easily reached by air travel or
sea travel. Despite the lack of roads, the Glacier Bay National Park and Preserve has
received an average of about 470,000 recreational visitors annually from 2007 to
2016, with 520,171 visitors in 2016. Most of the visitors arrive via cruise ships from
1890 to the present time, shown in Fig. 1.5. The number of ships that may arrive each
day is limited by regulation. Other travelers come on white-water rafting trips.
