Bridge Bay Marina

Xanterra Parks and Resorts at Bridge Bay Marina on Yellowstone Lake provides boat rentals and other boating services. Numerous outfitters operating outside the park are licensed to provide boating services in the park. Several dozen backcountry campsites line the southern shoreline that are accessible only by boat.

Two major hiking trails provide access to the lake shore away from the major road. The Nine Mile Post trail hugs the eastern shoreline into the Thorofare region and intersects with the Trail Creek and Heart Lake trails that touch the ends of both the south and southeast arms of the lake.
