The following guide is a compilation from several sources of some of the most interesting and scenic points along the Seward Highway. All milepoints are from Seward, the south end of the highway. Mile markers along the highway are placed every mile, but sometimes hard to see. If traveling from Anchorage, you are starting at approximately mile 127 and mileposts will be decreasing as you travel south. As most travelers start in Anchorage, I have posted these points starting at the north end of the highway going south.
Miles 127-79: The highway heads south through Potter Marsh, a wetlands area formed during the 1964 earthquake when the land in this area sank. This is a great area for bird watchers most of the year. After Potter Marsh, you will pass Beluga Point on your right. This is one of the first of many scenic pullouts along the highway. Beluga Point is so-named because beluga whales are often spotted in the water along this area of Turnagain Arm. However, I saw none on the day of my visit. Continuing southward, the high rocky cliffs on the left side of the road just beyond Beluga Point are a good place to see dall sheep. On both of my visits to Alaska there were dall sheep feeding in this area. It helps to have a telephoto lens and/or binoculars for viewing and photographing these animals as they precariously balance on the sides of the cliffs. You will then continue through the community of Girdwood, home of the Alyeska ski resort, and a good place to pull off for a break. On either side of Girdwood the highway goes through several avalanche areas, and in the winter the highway may be closed at times due to avalanches. Finally, at mile 79, the road to Portage Glacier and the Whittier tunnel turns off to the left.
Miles 79-75: The highway now curves and skirts around the end of Turnagain Arm and starts back toward the west, on the south side of the Arm. Twenty-mile flats, this area of relatively flat, marshy land, provides some amazing views in all directions of the mountains, glaciers, and Turnagain Arm. The highway then turns back to the south onto the Kenai Peninsula.
Miles 75-69: A series of steep inclines takes you up and over Turnagain Pass. At this latitude, it does not take long to climb above the tree line. Unlike my experiences of mountain driving in Colorado, New Mexico, Utah, and Wyoming, the road here is pretty straight and the inclines are not as steep. The mountain passes in Alaska are much lower than those in the Rockies in the Lower 48. At mile 71, there is a pullout with a waterfall right next to the highway. If you are driving south, the waterfall will be behind you; you will need to stop and get out to really see it. A few miles down the road, the rest area at the summit of Turnagain Pass provides great views, has restrooms, and there is a paved trail down into the alpine meadow to a creek. It's a nice place to get out and walk and enjoy the cool, fresh mountain air.
Mile 56.5: The Canyon Creek rest stop is just before you get to the junction with the Hope Highway. The parking lot has an overlook where you can see where Canyon Creek flows into the north-flowing Sixmile Creek. The Hope Highway follows Sixmile Creek back to Turnagain Arm and the old mining community of Hope, a great side trip that not many people make. The drive to Hope is 17 miles, and will take about 25 minutes.
Miles 57-46: After leaving the junction with the Hope Highway, you will climb back above the treeline and pass a number of lakes in the valleys between the mountains. At mile 46, the Summit Lake Lodge provides a good rest stop with motel rooms, a decent restaurant, and a nice gift shop with a coffee bar and ice cream parlour. The lake is gorgeous and if the wind is calm, provides beautiful reflections of the surrounding mountains. See the dining entry in this journal for a review of the Summit Lake Lodge restaurant.
Mile 36: At this point the Sterling Highway turns off to the right to go to Homer and Kenai. The Seward Highway continues to the left. At this junction is Tern Lake, a beautiful lake with frequent bird spotting and yet another good place to stop and walk around. There are picnic tables on the west end of the lake.
Mile 33: The trailhead for the Carter Lake Trail, a popular hiking trail that will take you about four hours to do.
Mile 30: The community of Moose Pass is a quaint little town on the shores of Upper Trail Lake.
Miles 22.3-18.5: The highway passes the blue-green waters of Kenai Lake.
Mile 23: The Ptarmigan Creek Recreation Site offers camping and the Ptarmigan Lake Trail, a scenic hike along Ptarmigan Creek to Ptarmigan Lake. The hike will take about 2-3 hours to do roundtrip. See my review of this trail in this journal for more information.
Mile 3: Just north of Seward, Exit Glacier Rd. turns off to your right. Unfortunately there is no advance warning of the turn to this popular destination, so be prepared for semi-lost tourists slamming on their brakes when they see the sign right at the intersection. Be smart. If you have not been watching the mileposts, don't slam on your brakes in the middle of the highway's curve at this intersection, but continue on a short distance until it is safe to slowly turn off the road and make a u-turn back to Exit Glacier Rd.
Mile 0: The highway ends at the Seward waterfront, near the Alaska Marine Life Center.
