Since 1945, these historic glass-bottom boats have given people of all ages an in-depth look at the natural beauty of Spring Lake, where thousands of springs bubble up from the Edwards Aquifer. These springs are the key to a unique ecosystem which is home to eight endemic speces listed by US Fish & Wildlife and Texas Parks & Wildlife as threatened or endangered.
Spring Lake is home to one of the most dense turtle population's ever studied in the United States. The water's constant temperature ensures that there is turtle activity to be seen during any season.
Spring Lake is also a major fly zone for migrating birds. Whether a photographer, scientist or vacationer there is something for everyone to learn about and enjoy.
