Riding the Edge of Alaska: A Turnagain Arm Road Trip on the Seward Highway
Glaciers, bore tides, and big-mountain drama—one of America’s great coastal drives delivers mile after mile.
The road slips out of Anchorage and immediately picks a fight with the sea. To your right, the Chugach Mountains rise in slabs and ribs; to your left, Turnagain Arm flexes its famous tides, pushing a curling bore that dares surfers and kayakers to keep up. The Seward Highway doesn’t waste time. It steers you into Alaska’s scale—clean lines, hard edges, no filler—while the land narrates in tides, glaciers, and the steady beat of the railroad running alongside.
Trail Wisdom
Time the Bore Tide
Check Anchorage tide tables and aim for big minus tides to catch the Turnagain Arm bore tide at Beluga Point or Bird Point.
Use Designated Pullouts
Never stop in the travel lane—use signed viewpoints for photos and wildlife watching to keep traffic flowing and safe.
Download the Audio Tour Offline
Cell service is spotty beyond Anchorage; download the self-guided tour and maps before you depart.
Watch for Wildlife on the Shoulder
Moose and Dall sheep often graze close to the roadway—slow down at dawn and dusk and keep a long, respectful distance.

Conservation Note
Use established pullouts and boardwalks to protect fragile tidal flats and vegetation; keep at least 100 yards from bears and never approach wildlife.

Common Questions
Do I need a 4x4 to drive the Seward Highway?
No. The highway is paved and well-maintained; standard vehicles are fine. In winter, proper winter tires are strongly recommended.
How long does the round trip take with stops?
Without stops, Anchorage to Seward is about 2.5 hours each way. With pullouts, short walks, and a visit to AWCC or Portage Valley, plan 6–8 hours.
Where can I see the bore tide?
Beluga Point, Bird Point, and Turnagain Arm pullouts are popular. Check tide tables and arrive early to set up.
Are there restrooms along the route?
Yes—Potter Marsh, Bird Point, Portage Valley facilities, the Alaska Wildlife Conservation Center, and several highway waysides offer restrooms.
Is the audio tour available offline?
Yes. Download the tour in the app before leaving Anchorage to avoid service gaps.
Do I need any permits or passes?
No permit is required to drive the highway. Some sites—like the Alaska Wildlife Conservation Center—charge admission; day-use fees apply at certain recreation sites.
What to Pack
Layered clothing for fast-changing coastal weather; a charged phone with the audio tour and offline maps; binoculars or a zoom lens for distant wildlife; snacks and water so you can linger at pullouts without rushing back to town.
Did You Know
Cook Inlet’s Turnagain Arm has one of the world’s largest tidal ranges—over 30 feet on big exchanges—and can produce a bore tide that travels up to 10–15 mph.
Quick Travel Tips
Check tide and avalanche forecasts before you go; fuel up in Anchorage and top off in Girdwood or Moose Pass; allow extra time for summer construction; never walk on the mudflats—Turnagain silt can trap like quicksand.
Local Flavor
Refuel in Girdwood with sourdough pancakes at The Bake Shop or wood-fired pies at Chair 5. In Seward, Ray’s Waterfront serves halibut with harbor views, and Resurrect Art Coffee House pours a solid latte in a converted church. Back in Anchorage, celebrate the day with pizza and craft beer at Moose’s Tooth.
Logistics Snapshot
Closest airport: ANC (Ted Stevens Anchorage International). Start: Anchorage; End: Seward (127 miles one way). Driving time: ~2.5 hours each way without stops. Cell service: Intermittent beyond Anchorage and Girdwood. Permits: None for the highway; site-specific fees at recreation areas and AWCC.
Sustainability Note
This corridor borders sensitive tidal flats and wildlife habitat—use established pullouts, pack out all trash, keep vehicles off vegetation, and give animals wide, stress-free space.
