Mt Allen (#26 on ADK 46'er list @4,340ft) is very difficult mainly because of how long it is. 18 miles round trip. This is a pretty unfulfilling hike with not many great views. However, you will have a few stories once you finish it. After signing in, you'll follow the path down to the Hudson River. You'll cross a suspension bridge and continue another few minutes to Lake Jimmy. There is a detour around the lake but if you look you can see pieces of the old bridge still floating around. Continue on the path to the old Ranger building. Feel free to check it out. Stay on the old road till you come up to a carin and turn left. There is an arrow marked on a nearby tree stay straight and follow yellow markers on the trees. You'll come up to an old red gate, jumped and continue on. At about 4 miles in, you'll need to cross a river. There is no bridge and depending on the water level you might be able to jump rocks just 100 feet up river. Bring water shoes if you decide to ford it. For the next 1.5 miles its pretty narrow and overgrown but easy to follow. You'll pass a sign for Mt Marcy, just keep going past it and you'll run into a sign for Allen and a yellow arrow pointing the way. 5.25 miles in, you'll come to a road and some arrows on trees, go left and you'll see a gravel parking lot on the right. At the end of the parking lot is a second trail register. Sign in and continue on. From here, it starts the unmarked trail. Still pretty easy to follow, you'll cross a few streams, and pass a few water falls. One waterfall is marked by a cairn and this indicates 1 mile to the summit. It's very steep and slippery so be careful. Once on the summit, there is a small clearing and Allen Mountain sign. Then just follow it back down when your ready. Good Luck.

If you hike this past mid October, I highly suggest you pack micro spikes. 90% of the assent was cover in ice.
This is a LONG hike. It took me about 8 hours 40 minutes of straight hiking to complete it (not counting some brief breaks). If you're not going for your 46, I would leave this one alone.

Awesome way to spend a day in the woods! We had perfect weather! Believe me when I tell you there are AMAZING views from the top, literally 50 feet past the summit sign and you don’t have to bushwack to get to the spot. Photo opportunities of the Great, Dix, Santanoni, MacIntyre, and Seward ranges. 12 hours car to car with an hour lunch at the top and a couple smaller breaks. The slippery red slime on the rocks in the last mile can be less problematic with micospikes, which my hiking buddy had...shout out to Anthrax for getting peak #41 this day. The 8-mile approach trail passes by scenic Jimmy & Sally Ponds and crosses the Hudson & Opalescent Rivers on beautiful suspension bridges. Don’t believe the nay-sayers...I think you’ll enjoy this hike!

This was my second time hiking Allen. The hike in to the base was quick, but I was slow going up and down that last mile of elevation gain. I took nice pictures of the ponds just off the summit.

Peak number 4 for me. I felt it was easier than the Santanoni/Couch/Panther trio, but this mountain was still a hell of a climb. I completed the hike in 8:42, but after getting my ass beat on the other three I mentioned, I’ve been working hard to get into halfway decent shape before doing this one. All but the last mile is relatively easy. It took me about an hour to complete the last mile going up and about an hour to get down. It’s slick and you will get your feet wet. Take your time and you’ll be alright. As of middle September, bugs were pretty much nonexistent. The trail is fairly well marked and easy to follow.

Unless you are set on completing the Adirondack 46, I’d skip this one. I will not do this hike again.

We did this back on 9/1. The forecast was only 15% chance of rain for the day and of course when we got out of our car at the Upper Works east trailhead lot at 5 am it started raining. And didn't stop for most of the day... so obviously the trail was wet and muddy. The trail was easy to follow and flat the majority of the way. Except that last mile-ish up to the top (after the waterfall with the cairn marking the trail to the right). Most of it really wasn't as bad as I had heard, and in fact I think there may have been nice views going up to the peak if it hadn't been cloud-covered and raining. We got to the big rock slide and went up the right side. Wrong choice. There is a very small cairn at the base of the slide, go up the left side here. We ended up having to bushwhack up to the peak because the right side of the slide doesn't bring you back to the trail. Other than that part of the hike we actually didn't mind this trail. It took us almost exactly 12 hours roundtrip, I think we were a little slow making our way up to the summit due to the rain making an already slippery trail that much more slippery, so we were trying to be safe/cautious. Also, the 2 new suspension bridges kept us out of the deeper water. Any other crossings were shallow enough to cross using just the rocks as steps.

If you’re hiking Allen you’re typically trying to hike all 46 high peaks. This hike took me 9.5 hours car-to-car. The first 7 miles is flat terrain getting to the base of the mountain. It’s boring but at the same time is kind of neat and unique and a lot of time can be made hiking this portion quickly. There aren’t other trails like this while hiking the high peaks. Lots of open meadow-type clearings, hiking along old abandoned roads, lakes, going over multiple suspension bridges, and an abandoned cabin. It’s actually cool just really long. Going up Allen however is super slippery (the Red slime is real and very slick). Trekking poles and/or micro spikes are very useful on this trail due to climbing all the slippery slides/slabs. Fully wooded summit with summit sign. A few clearing views throughout the hike but there’s a reason people often don’t care for this hike; a lot of work/miles with little payoff. But it’s not as bad as some people make it out to be in my opinion.

It’s a long hike just to get to the base of Allen. The trail is easy to follow. The hike was generally boring, with not too many views. The climb to the top followed a stream that was filled with slippery wet rocks. The summit had a few nice views, but to effort to get here should only be done if you want to complete the 46ers. There are many better hikes with much less effort that offer a greater wilderness experience.

I hiked this trail on July 20th.
It had been dry for many days which helped when you get to the scramble near the peak.
The red moss is extremely slippery and I took one fall on the way up.
Many people I saw coming down had taken a few falls on their butts due to the moss so be careful.
If possible I would watch the weather and wait to do this after a few dry days.
This is a very long approach (and therefore decent) so make sure you have plenty of water.
The raspberries were plentiful along the way and made for some nice snacks.
I would also recommend a bug net as the flies were relentless when I was coming out around 6 PM.
The views just before the summit and right past are pretty nice and the dragon flies were amazing.
Number 41 is in the books.

Aspiring 46er and this was a great hike due to the great views at the top(past the summit sign). The flat start with intense elevation gain at the end is definitely a challenge! Took us 11.5hrs which includes an hour spent at the top.

This is a long hike and I would imagine mostly done by people bagging all 46 High Peaks. The scenery along the way is nice but there is not a lot of it. Overall, the approach trail is pretty tame stone/ gravel work road - boring. It was very muddy in areas. There is red algae or moss on the slide that is the most slippery section I have ever encountered. It was nice to see the new bridge not mentioned in the ADK High Peaks guide book. The summit is treed but we did get some nice views. There is certainly a sense of accomplishment from covering this distance and with a friend, you should have some great stories.

I'm thinking of going up there tomorrow 5/20/2018. Any idea if there is any ice up there now and if crampons are needed? Also, I'm thinking of camping overnight somewhere on the way. Any recommendations?

Lots of snow melt. Crampons recommended for the steep ascent. Snow waist deep on top. Post hole frequently. Beautiful rivers. An excellent hike and took 13-hours. Less time, had I brought crampons.

Attempted on 1/10/18 and had to turn back right at the base of the slide. It took me 4.5 hours to make it that far due to the snow. I had to break trail the whole way and in some places I sunk in over 2-3 feet deep even with snow shoes so keep in mind. Very difficult trail with snow. Know your limits and don't try and overdue yourself because even at the summit you'll have 9 miles left to go back.

The first half of the trail is relatively flat but oh so much mud and bog to skirt! Made for a lot of hopping and even fighting through thick bush around a deep swamp. After the second register the trail is more soft and pleasant, but the last mile is very steep and slippery. I fell at least 3 times, twice hard, and once scraped up my arm pretty well. There is a nice view a few steps further from summit. We sat for 40 minutes eating bagels with cream cheese and salmon, followed by chocolate cake and coffee. We then chatted with a group of 4 men we'd been leap-frogging all morning. All in all an hour on top, which is long and luxurious for us! It took about 4.5 hours up and 4 down.

Allen felt very much like Seymour over in the Sewards, just add about 6 miles to its length. I had been pushing this hike all year trying to do it with a few days of dry conditions and low water levels. Attempting it in early September it was a perfect day with the leaves changing, temps hovering in the high 50's-low 60's, and for how much I wanted to dislike the hike due to its length I just couldn't bring myself to do it. Yes my feet were a little worn by the time I finished but it was definitely a pleasant experience.

If you plan on doing this hike as a single day outing, definitely set aside some time for this one. Not realizing how far the trail head was from Lake placid, I had started later than I had hoped @ 9:15am. I had estimated I had a good 10 hours until sunset- finished in 9 hours and 50 minutes. Try not to cut it as close as I did if you can.

Trails are very easy to follow as the first 5 miles are on an old road. The herd path after the 2nd reg. box was at times even easier to navigate than the DEC trail. Just keep close eye on the trail as you ascend in the last 1 mile. Stay to the right of the river as you ascend-then to the left as you reach the last (and steepest) summit scramble- Its pretty obvious for the most part but with leaf cover like I experienced- it can make it easier to lose.

*Note* The gentleman who had mentioned the red moss on the slabs as you ascend Allen was 100% correct. Very slippery as I had pulled a Charlie Brown on the way down.

*Note* As of September 2017, unlike what the original write up for the hike states, there is now in fact a 2nd suspension bridge at the 4 mile mark- no fording necessary

Allen was tough only because it is a long hike. Many miles of mostly flat and then you gain all the elevation in last 2-3 miles. I did not think this was as tough as many other High Peaks, though, in terms of actual difficulty climbing. We hiked this as a backpack trip. Hiked in roughly 6 miles from Upper Works to Allen Trailhead. Stayed at the junction to Allen and Marcy and set up tents on an old truck road. We hiked Allen Saturday then Marshall Sunday through Flowed Lands then hiked out Monday. All in all, a good hike. This was 41/46 Peaks hiked for me. Recommend as backpacking trip versus day trip if you are a slower hiker or want to enjoy the hike without worrying about time. Nice views along the hike including a waterfall. Views at the top past the wooded summit.

It's a myth that Allen has no views! There are certainly some vantage points along the trail and just beyond the summit. The newly opened logging roads are easy as cake, though the final ascent is steep and slippery. It's a long day, with beautiful flowers and sore feet.

Unless you need a real challenge or one of your 46 peaks pass on Allen. Last mile is formidable but rewarding. Few photo ops. Even the Ranger said Allen is "brutal"

Friday, August 11, 2017

This was an interesting one. I felt like I was doing two trails 1) a walk in the woods, and 2) running as fast as you can up a wet slide. Feeling very accomplished though after completing.

July 2017: This was a really tough climb due to 5 days of rain that preceded our hike. The entire "easy" part of hiking to the mountain on relatively flat ground was not so easy. Bogs, mud and a heavily flooded trail forced us to practically bushwhack every 100 feet or so. It made the first 6 miles very slow and arduous. The trail up Allen was very steep for the last 3/4 of a mile and lots of slippery slides to navigate - due to all the recent rain. Under normal conditions this would have been a wonderful climb, albeit long. It has great views from the top about 35 feet beyond the actual top. On the Marcy side of the mountain. We hit the trail at 7:20am, reached the summit around 2:45 and ended back at the parking lot just before dark at 8:45pm. Once again, our slow speed was due to the bogs and mud along the way. I highly recommend avoiding this trail right after significant rainfall but would be happy to climb it again after several days of dry weather. It's really a beautiful trip the entire way. Just make sure you bring a flashlight, just in case!

Tuesday, July 04, 2017

Allen has a bad name for being a "hard" hike. It's a longer hike for the Adirondacks but isn't to awful in my opinion. Be careful on the redslime once making your way up the slide and you'll be okay. Enjoy

Saturday, June 24, 2017

Great view. Faaaaar. Went with Todd n Frank. Last mile we ran top speed because of lightning. Crazy scary. But good way to cool off!

Saturday, June 17, 2017

This was an easy hike for the first 6 miles before you had to start climbing to the summit. The insects were horrible even with spray on.

Tuesday, January 17, 2017

Long day, hiked 10:30 hours, great views along the trail. Started 7:00 am and summited 1:00 pm, used snowshoes and crampons. Great day, no winds, sunny and clear. Some part of trail were hard because of Thawing conditions.

Hiked out and planned to stay the night near the peak, and then summit the next morning. If something doesn't go wrong, then it's not an adventure...My brand new tent came with no poles, which was easy enough to over come with some rope. The hard part to beat was - no rain fly! We camped about a mile from the peak and the weather was good until about 3:30 am. Rain and wind, three of us had to sleep underneath the tent. Worst trip, for me, so far.
The hike was good though. The trail is easy and nearly flat until you get to the base of the mountain. I'll be back!

nice waterfalls, great birding spot, and an all around good full day workout. start around 6 am when you have full daylight hours. very remote, so pack extra water and plan to stay overnight if you get tired.

Monday, October 12, 2015

First high peak for me. I am a very athletic person and I will say this hike definitely exhausted me. The mud, slippery climb up and slide down was rough on my knees as well. Glad this one is done for me.

Friday, July 10, 2015

This is a very difficult mainly just because how long it is. Get an early start, and watch the weather. Its fairly muddy on most of trails. The old roads are in really good condition. The path is pretty easy to follow. Just once you hit the waterfall marked with a cairn, it is 1 mile to the summit. With about 50-60% incline to get there. Good Luck.
