Mt. Wire (commonly referred to as Big Beacon by locals) is one of the prominent foothill peaks due east of downtown Salt Lake City. The peak is easily recognized by the two large reflector panels just south of the summit, used for transmitting telephone signals between Salt Lake and Park City. Atop Mt. Wire is an old airway beacon, which you can climb should you desire an extra 25 feet of elevation. While Mt. Wire is a relatively low elevation peak, it is an outstanding spring hike of over 2,000 vertical feet with incredible views in every direction, rampant wildflowers, and wildlife that includes the occasional rattlesnake or mountain lion. In most years the peak can be hiked free of snow in April, and is an excellent tune up for the bigger mountains.

I used to hike this from the prominent south ridge as training for the Grand Teton. I’d hike it everyday, 20 minutes up and a little less down. I might add that I was mostly running or moving very fast. It was a great hike. I used to climb the beacon just for the extra 30’ of view. It’s too bad the microwave reflectors aren’t up ther anymore.

Great trail, there is a decent amount of shade, but would be better as a morning or evening hike. Did see a rattler so watch out.

Great morning hike. Pretty heavy foot traffic until you pass The Living Room. After that the trail narrows and gets muddy. The view at the top is well worth checking out.

Trail was muddy after the turn from the living room. Along the final climb spikes were very useful because of the hard ice up.

Completed this hike on 2/3/18. This is always a great easy-moderate hike with great views of downtown SLC and plenty of wildlife. Lots of wind at the summit, but still worth it.

I did this Thanksgiving morning. I went up to the Living Room on the much less used trails behind the Museum of Natural History, and then got on the Mount Wire trail that starts at the sharp U-turn in the back of the canyon where the main Living Room trail comes up. Note that it appears that climbing up to up to the Living Room is a very popular thing to do on Thanksgiving, but very few people take the trail to Mount Wire. It's not very interesting at first, as you are just going uphill through the trees, but then you emerge out into open terrain and the views are great. There's a 4 way intersection in the trail where you need to take a sharp right turn to get up to Mount Wire, which involves some significant elevation gain over a short distance. The views are worth it, and it is awesome to think that you can have access to something like this right off the city streets. The tower is surrounded by a chain link fence topped with barb wire, but the gate is open, so you can climb up the ladder if you are so inclined. There are various trails going off in different directions from the tower, so that would be fun to explore sometime. Going down there were hordes of people coming up the Living Room trail, which right now is spectacularly and inconveniently muddy in some places.

Fun and low traffic once you get past the Living Room. Awesome view of the valley and the radio tower is a cool climb if you're up for it.

Hiked this today. I really enjoyed it! I feel a moderate rating is appropriate. It was an incline the entire way up so no flat areas, but it wasn't as grueling as some other hikes in the area. The last mile or so is steep and I felt myself resting more frequently. The elevation contributed to that as well.
There is a small tower a the summit that's fun/scary to climb. If you climb it though, you get an uninterrupted 360 degree view of the valley. Breathtaking. If you go in the fall you'll be rewarded with some beautiful foliage.

This was one of the most beautiful sunset hikes I've done! It's definitely very steep, and I slipped almost the whole way down but the sunset views were well worth it. It's pretty open for a majority of the hike but it does get pretty narrow/woodsy up one trail to the top. The living room is a great place to watch the sunset if you don't want to go all the way up.

So I reviewed this trail last summer, but it was so HOT and arid. However this morning a few of us got to the trailhead at 4:30am with our dogs ready to go! We got up to the top a few minutes before the sun was going to peek over the mountain, and it was glorious! I HIGHLY recommend this trail for a sunrise hike. I've hiked a really good amount of trails in the wasatch mountains, and I can't think of a better sunrise hike than this. AMAZING! We heard a bunch of coyotes going crazy when we got to the top. Also, don't do it that early alone because it's definitely a place where the mountain lions would love to hang. ;)

A small hiking umbrella would be a nice addition to the kit for this hike. The day I went, the Livingroom Trail section was sidewalk busy. Going higher, the crowds thinned out. Take a minimum of 2 litters of water for a hot day.

This hike is best for spring and fall. It get's very hot in the summer. Great views of the valley from the top and fun to climb up the radio tower. Very busy trail for the first 1/3 of the hike but once you pass the Living Room turn off it is pretty quiet.

The ridge part of this loop is very rocky and a nice challenge.

good moderate hike for the start in prep for kings peak.

Fun. Don't miss that turn above the gravelly hill on the way down!

There's a nice radio tower to climb up and just stare down at the valley when you get to the top

Definitely do not try going down the right part of the loop without a pair of pants you can ruin by sliding on your butt or some sort of specialized equipment. I'm not a native, but I've never been on this steep and rocky of a trail in my life. Probably really fun to sled on in the winter, though!

Good hike to do in the evening.

Great hike, still a little snow and muddy in spots. The steep "short" part of the trail was a little tough coming down on the knees but the hike was gorgeous!

A great Sunday hike that ended at the "living room". A tad muddy in a section

Solid training hike for spring and winter

The trail is mostly clear of snow now, but there is still a lot of deep mud. Once I got off the main trail I didn't really see too many people. It was a great way to spend Presidents' Day!

I was wearing spikes but the snow was packed all the way up. Not a hard hike, but great views.
