Leave Anchorage by train and head down along the shore of Turnagain Arm where beluga whales feed on small fish and salmon head to spawning grounds. This area is part of the six-million acres of Chugach National Forest-the second-largest National Forest in the United States. Travel through Girdwood and watch for salmon in the streams along the way before you enter the first of two tunnels to enter Whittier-the gateway to Prince William Sound. You'll continue south down to Placer Valley leaving the highway behind and into the countryside only accessible by train. You'll stop at Spencer Glacier among wildlife habitat populated by bear, moose, coyotes, and wolves. Next, step off the train at the Spencer whistle stop for a self-guided two-mile hike. The trail leads to Spencer Lake for spectacular glacier viewing. Upon completion of the hike, hop aboard the Alaska Railroad for a short trip back to Portage. You will then board a deluxe motor coach for the transfer back to Anchorage.
