If you want to go sea kayaking or whitewater rafting, this is the company you want to book with. Offering sea kayaking day trips as well as overnights in Prince William Sound. People come from all over the world to go sea kayaking next to the Columbia Glacier, which involves a 2.5 hour boat ride where you will see sea lions, sea otters, and maybe even orcas and humpback whales.
Pangaea also offers half day whitewater trips through Keystone Canyon on the Lowe River. I personally think this is the most scenic road side river in the world. They'll get you under Bridal Veil Falls which is only accessible by raft.
