So, it's kind of hard to find information on this trail, so I'll help ya'll out…read more
GETTING HERE: From the Seward Highway, go north (a right if you're heading towards Anchorage, a left if you're heading away from Anchorage) on Boretide Rd (right next to the new Turnagain Arm Pit BBQ location). Where the marker is for this Yelp listing, is where the paved road ends. Just keep going straight! The road can be a little bumpy but nothing that would require high-clearance or 4WD/AWD. Eventually, after what seems like a long time (but isn't), you'll end up at the trailhead.
Officially, this trailhead is called "Indian Valley Trailhead". Chugach State Park's website is horrible (they have some great .pdf's for some of their trails, but good luck finding them anywhere on their website...), so I was only able to find most of this information from: googling, using summitpost (a climbing website), and browsing blogs. Hopefully, this consolidated source of information will be helpful to some!
From this trailhead, you can access two trails:
Powerline Pass: which has its other end at the Glen Alps area (Flattop)
Indian Valley Trail: a trail of controversial quality (I have never done it) that goes NE from this trailhead and eventually meets the Ship Creek Trail.
(About 1/4 of a mile up the trail you'll come to a junction: if you go straight you'll be on Indian Valley Trail, if you take a left, and go over a footbridge, you'll be on Powerline Pass trail)
I'll be mainly speaking of Powerline Pass.
Most folks start Powerline Pass up near Glen Alps. Most folks mountain bike* it, rather than hike it. Most folks would need a bike with a good suspension to do this. I do not have such a faithful, two-wheeled steed, so I hike.
Why hike it from this side? A couple reasons:
1) This is the approach hike to climb Homicide Peak: this is how I originally found the trail. Homicide Peak is a fun scramble with awesome views of the Suicide Peaks. More info on climbing Homicide can be found here: http://www.summitpost.org/homicide-peak/815642
2) Crowds: there aren't many. This trail isn't as well-known or popular as many others in the area.
3) Feasting options: Froth and Forage (https://www.yelp.com/biz/froth-and-forage-coffeehouse-and-eatery-anchorage) is open till 10 pm, and located very close to this trailhead. Hiking early in the morning? Stop in for a coffee. Hiking late in the evening? Stop in for a burger!
4) Get out of your usual rut: expand your mind, hike some new stuff!
Reasons you might want to be a bit leery of this trail:
1) I've heard the Indian Valley Trail can be miserable and overgrown in spots. I hope you like bushwhacking. Or 'schwacking, for short.
2) There can be lots of bear activity in this area. Carry your spray, take your dog, hike in a group.
3) If there's been recent rain, it can get pretty muddy.
Definitely, give this trail a shot!
