    halfway point

    My main tip for doing this hike would be: Watch the weather in Whittier like a HAWK. There is a reason that a certain word starting with "S" and ending in "ittier" is often rhymed with Whittier. This place gets over 200 inches of rain a year. Not sure if that's a lot? Seattle gets about 36 inches. Anyway, watch the weather, and if you catch a sunny day, high-tail down the Seward Hwy, pay the man at the tunnel, exit the tunnel, and hook an immediate right. This brings you to the trailhead, parking is limited. Carpool if you can. The hike is fairly moderate but is the classic "uphill both ways" hike. You go up to a pass, then back down again to Portage Lake. It's about 2 miles with 800 ft of gain, one-way. As far as what it looks like, check my photos. They describe it better than I ever could. You can walk along the lake to scramble right up to the Portage Glacier. I wasn't able to do this since I wanted to make dern-sure that I didn't miss the last (11pm) tunnel crossing. If you want to watch the sunset on the Portage Glacier (worth it) you can even throw down a tent on the shores. I might try to do that next time.

    Outstanding trail. It has everything you want to see in Alaska- soaring peaks, colossal glaciers, icy rivers and waterfalls, berries for forgaing, trees and tundra alike, and views of Prince William Sound to die for. And that's all in the first mile. Granted that first mile is entirely uphill... it takes my fat ass well over 90 mins to make the 800 foot elevation gain. But it is Soooo so worth it. The trail is murder on your calves and knees because it's all loose rock at about a 15 degree incline. Going up and down is hairy even with a walking stick. But it's definitely doable, even for the elderly or out of shape if you just pace yourself. The signage isn't great to find it. AS SOON as you come out of the Whittier tunnel on the right start looking for the small sign that points you to the park. Go down the dirt road and make the first right. There's no parking lot it's just a free for all. Get ready for an amazing experience! Enjoy!

    This hike is amazing! Medium level of difficulty. Would be good for kids a little older (maybe 7 and up?). First mile is a climb but after that it is easier. Spectacular views of mountains, waterfalls and glaciers. Went on a Sunday afternoon and it was rather busy. To get to the trail head you must go through the Whittier tunnel so take that into account when planning this hike.

    Portage Glacier, a brilliant reward in the middle of a fun hike.

We saw senior citizens, kids, dogs, etc. all comfortably share this path. I took my husband and parents who are in their 60s to this trail. My parents aren't too fond of when I take them on what they call "too crazy of an adventure," but this trail they handled just fine. It only took 55 minutes to drive from Anchorage to the trail head. And you get to drive the beautiful scenic Seward Highway. That itself already made the trip worth it. The trail is only 1.4 miles one way. There are no river crossings or switch backs. It's just out and back. It's a pretty sunny walk, so bring a hat/sunscreen. At the endpoint, you get a nice view of the Byron Glacier. Apparently you can even sometimes visit ice tunnels. Those weren't available when we went because an avalanche reportedly happened the week prior. But it was still definitely worth the trip. If you take your time to enjoy the walk and glacier, the "hike" takes about 3-4 hours.

This is the Tony Knowles Coastal trail of Portage. You start at Moose Flats, or Visitor's center, and walk/jog/bike/skate/meander 5 miles to the opposite end. I started at Moose Flats and it was a good time viewing natural and unnatural areas of interest. Scouted out camp spots, watched kayakers in a lake, and enjoyed walking over bridges during the jaunt. It was good, not great. So much so, that instead of walking all the way back I hitched to get the car and pick up walking companion. Then we jetted over to Byron's Glacier for a proper, albeit shorter, hike. Would come again if camping in area, but would pass for future hiking funsies due to lack of interest.

Despite being located a little over an hour from Anchorage, this area gets obscene amounts of snow and rain. As a consequence of all that H2O falling from the sky, the mountains in here are heavily glaciated, even though they are not very tall by Alaska standards. (tallest in the area is around 6,000 ft, with many in the 3,000-4,000 ft range) Because this trail is so flat, it's very commonly cycled. Bring your bike and make a half-day of it, or bring only your boots for a much fuller day. There are places to view Salmon here, but I can never seem get the timing right.

    Man, how am I just now getting around to hiking this?!…read more Falls Creek is located at ~Mile Post 105.6 on the Seward Highway. In relation to other trails: To the West: Rainbow Trailhead (https://www.yelp.com/biz/rainbow-trailhead-anchorage) To the East: Indian Valley Trailhead (https://www.yelp.com/biz/indian-valley-trail-anchorage) Stats: Mileage: 2.7 (one-way) Gain: 2,900 ft About a 1,000 ft/mile, steep but not *too* steep. The trail starts out...next to a falls! It closely follows Falls Creek for the first half of its length. As the water is loud and the brush is thick, I'd highly recommend doing some trail karaoke with your friends to make sure you alert any bears in the area that you're coming. Eventually, you get out of the brush and the valley expands. It's gorgeous. It's wide and it's bright-freakin'-green (my favorite shade of that color), or at least it was in mid-June. This is going to sound odd but, it actually reminded me of some of the valleys I hiked in Hawaii! It made me a little butthurt that I am only just-now getting around to hiking the trail. The trail ends at a lake. I'm not sure what the name of it is, so I'll just call it "Falls Lake". The lake frequently has snow on/in/around it, up until July. But, there is an ample amount of vegetated, snow-free flat area around the lake, this would be a perfect "Baby's First Backpacking" trip. (no permits required, just load yourself down and hike up) You can continue up past the lake, onto the ridge between South Suicide Peak and Indianhouse Mountain. The path will quickly change from "hiking" to "scrambling" though. I'd only recommend going up South Suicide if you are confident on your feet, and I'd only recommend going up Indianhouse if you have a rope and a partner! If you're quick enough, this can be done as an after-work hike. If you're slow or looking for a casual stroll, you can easily make a day of this hike.

Got back to the parking lot after 5pm. You'll need most of your day to do this hike if you're not a professional. This hike is beautiful but it is challenging for sure. You are going uphill the entire time. On the way down it's so steep you're jamming your toes trying not to fall. We did the bulk of this hike with nothing but backpacks full of snacks hahaha. Everyone that passed us up or down had poles, guns, bear spray, bells, dogs, the whole enchilada. I don't recommend hiking this area the way we did, we just got lucky :) It was a beautiful day and we were never alone for longer than 15-20min at a time. Weather was perfect, it was sunny and warm but the breeze was breezin'. The falls are a sight to see and made this strenuous hike completely worth it for my water-loving son. I can't wait to return soon and make it further.

    The first time I drove through Cooper Landing, I had a thought that went something like "Wow, this…read morearea is beautiful, look at that water! I wish I could see a better view of it though..." Since then, Cooper Landing has been a place that I have thoughts like this about: "Beautiful place, some good places to eat on the way to Homer, not much to do if you're not into fishing though..." Well, I discovered this terrific trail (along with half of the Anchorage metro last weekend), and I'm happy to report I was wrong! The trail is short (in mileage, a little over 2 miles) and steep (in elevation gain, about 2,600 ft). Going down will be 2 to 4 times as fast as going up. It took us about 2 hrs to get to the top, hiking at a steady clip with no breaks. We started late because, what the hell is the point of waking up early to hike when it's light out past 11pm? And we ended up having the summit to ourselves! Keep going towards the end, there are multiple "false summits" near the top where it feels like you're about to top-out, but you ain't. Here's a tip, try to impress/annoy your (masked, distanced) friends by yelling out "SORRY, FALSE SUMMIT!" as you hit each one! At the summit, amazing panoramic views of the turquoise waters of Cooper Landing abound! Great for testing out that panoramic functionality on that new phone you bought during quarantine! You also should've brought a beer, sorry I didn't tell you earlier in the review :( The trailhead is at the end of the short road called "Stetson Cir", navigate to it from the Yelp page and it should take you directly there. It's not formally marked with a sign or anything (nor are there any restroom facilities), but the start of the trail is very well-worn and hard to miss, it seems like locals use it to gather firewood.
