Hi, we'll be taking the Major Marine glacier cruise this Saturday. I think the cruise will be over by 6 p.m. My flight doesn't leave from ANC until midnight. We'll be traveling using a rental car. I figure the drive back to the airport will take about 2 hours. That leaves about 4 hours of free time. Any suggestions of things to do? We enjoy nature but are pretty open to any suggestions. I know we can stop along the road to sightsee, but any other specific recommendations of places to stop or parks nearby to visit would be greatly appreciated. Thanks!
