The Lost Lake Trail has long been renowned as one of Alaska's classic backcountry trails, and it's absolutely a must-hike if you're in the region! The hike begins from a trailhead outside the town of Seward by climbing through the deep Alaskan rainforest. The first few switchbacks on the ascent include some large technical features that might seem intimidating, but this isn't indicative of the rest of the climb.
While there are a few more big features on the way up, overall the trail tread is very manageable.
The climb up the mountain ascends consistently, gaining almost 2,000 vertical feet to the high point. After several miles of climbing, you'll break out above treeline and, on a clear day, enjoy stupendous views of the glacier-covered mountains around you.
Most notably, Mount Ascension rises to a height of 5,710 feet above sea level and towers almost directly above the trail! However, getting a clear day on the Kenai Peninsula is a rarity, so you need to be prepared to hike up into low-hanging clouds that obscure the view and that may very well rain on you on any given day.
But that's all part of the adventure when braving the Alaskan wilderness! You'll hike for miles above treeline, enjoying long-range views if the clouds are high enough.
But even if they aren't, the alpine tundra is often covered in colorful wildflowers in the summertime, providing their own unique micro beauty. This route tops out on a ridge and then descends almost 300 vertical feet back down to reach the shores of Lost Lake.
The views from the shore are stunning! Above and beyond the long-range mountain views, Lost Lake itself is surprisingly large for being tucked away so high in the mountains, and the water is crystal-clear.
Enjoy some delightful solitude on its shores before carrying on with the loop. The route shown here is an epic 32-mile backpacking loop that descends the Primrose trail and utilizes two sections of the Iditarod National Historic Trail (INHT) to loop back to the Lost Lake trailhead.
If you're feeling uncertain about your ability to complete the loop, it's a good idea to turn around at Lost Lake and return to the trailhead the way you came.
The full loop still has a ton of challenges to throw at you! If you choose to carry on, you'll soon be faced with a steep descent down the Primrose Trail.
Most of the trail follows an old mining road and is steep, eroded, and filled with technical obstacles.
Before you reach the shores of Kenai Lake, you'll take a right onto the Meridian Lakes section of the INHT.
The rest of the route traverses much lower elevations than the Lost Lake trail, meaning that you'll be spending a lot of time hiking through the rainforest.
There aren't many major climbs to tackle, but you'll have to power up a series of short, steep grunts. When you reach the Seward Highway, take a left along the highway and look for the Bear Lake INHT section picking up on the right in roughly 3/4 of a mile. The Bear Lake trail is yet another INHT segment that measures 7.5 miles one-way.
This section of trail also travels beneath the dense canopy and features some steep hills.
Most notably, there's a fairly steep descent down to the shores of Bear Lake. After passing Bear Lake, you'll have to use a series of roads and a portion of the bike path along the Seward Highway to make the connection back to the Lost Lake trailhead.
