    Ticket info /hours

    Your entry into the Biosphere is led by a tour guide who takes you inside and under the glass. The beautiful trail system takes you on a once in a lifetime tour that lets you smell our ocean and see a tropical Rainforest up close. In addition to escorting you through the upper Biomes, your interpretive tour guide takes you through the basement “technosphere” and into the amazing lungs that help the Biosphere system breathe. Your tour will conclude in the custom-built underwater ocean viewing gallery where you can explore the million-gallon ocean and its real coral reef. Before or after your tour, take time to enjoy the many different programs or events that are offered throughout the season. Your experience will be like no other!

    Also, stop by the visitor center which houses exhibits and multi-media displays along with a Bookstore and Cafe. You won't want to miss our new feature movie showing in the main theater which describes the past, present and future of the project.
