Spencer Glacier

The feel

Spencer Glacier is a remote wilderness area with no road access. You arrive by Alaska Railroad train at the Spencer Whistle Stop, and the glacier is a wall of ice cascading down the mountains to Spencer Lake.

From the station, a well-maintained 1.3-mile path leads to the glacier overlook on the edge of the lake. Guided floats use rubber boats among the icebergs on Spencer Lake before drifting down the Placer River. A Forest Service interpreter also tours the foot of the lake, and a guide steers an Alaskan Native canoe among icebergs calved off the glacier.

What to expect

What it is

A glacier and iceberg lake reached only by train, with a roofed shelter and the trailhead at the Whistle Stop station.

Time

The train reaches the Whistle Stop at 1:45 PM and leaves at 4:40 PM for the return trip toward Portage and Whittier.

Parking

No road reaches the site, so the train is the only way in.

Fees and passes

Round-trip train fares apply, and they vary by boarding town.

Kids

The guided float is mellow and suitable for ages 5 and up.

Bathrooms and water

Restrooms are at the Whistle Stop station.

Season and access

Late May to mid-September. Daily train service runs May 30 to September 14.

Mingo says

Plan your whole visit around the train times, because the 4:40 PM departure is your only ride back. Visit from late May through mid-September, when the Glacier Discovery Train runs daily.

Before you go

• Call Alaska Railroad reservations at (800) 544-0552 to add a float or other excursion.
• Reserve campsites through Recreation.gov if you want to overnight, since they are reachable only by train.
• Budget $94 to $154 for adults and $47 to $77 for children aged 2 to 11, depending on the boarding town.
