The scenic boardwalk is also the site of the park's most popular activity, jumping into Big Blue, said Brent Fournier, park manager. The spring is 25 to 30 feet deep. The long and winding boardwalk at Blue Springs takes you from the springs all the way to the Santa Fe River. Next to Big Blue lies Little Blue, a smaller spring that is actually 10 feet deeper than Big Blue. It's like there is another world there.
Fishing is also another great activity at the park.
Visitors may also rent canoes and tubes to use in the springs. Apart from Big Blue the park has eight springs that are kept in their natural state. They have not been altered in any way. Big Blue is different because it is surrounded by the boardwalk and it is also periodically cleaned. Naked Spring and Johnson Spring are completely natural.
