Valdez - Walking on Glaciers

Are there any kind of tours for 4 people in September to hike on the glaciers from Valdez other than a helicopter ride?

I know we can do it from Anchorage.

Valdez seems to be a place we can do lots of activities from the downhill bike ride, to seeing brown bears, salmon fishing, kayaking around the glaciers and the small boat wildlife/glacier cruise.

I understand there are 5 glaciers in the area but I don't see any glacier hiking tours (other than the really pricy helicopter tours). Or should we just do the glacier hiking tour from Anchorage?
