Hike Allen Mountain

Enjoy the day in the remote wilderness with a beautiful hike and challenging slide climb to one of the Adirondacks' 46 high peaks!

Parking for Allen is in the history filled town of Tahawus. This area is known as the Upper Works. The parking will be on your right shortly after the Old Blast Furnace from the mining days.

After signing in the trail takes you quickly to the crossing of the Hudson River (there is a bridge here) and then shortly beyond that is Lake Jimmy. In the winter when solid you can walk across the Lake however, there is a route to the left leading around the shore of the Lake. Hurricane Irene in 2011 destroyed the bridge across this lake. Shortly after you will pass the old caretaker cabins for Mount Adams Firetower and the trail on your left. Continue straight along the old road. You will remain on the old access road for quite some time, but leave it now and again to a foot trail.

At approximately 3.5 miles into the hike you will reach the Opalescent River. You need to do your research beforehand and make sure it is crossable. It can get very high and fast moving. Once pass here you have several more miles of rolling terrain and the Skylight Brook to cross.

Shortly after Skylight Brook enjoy the dense forest before you reach the base of the climb! You will then climb the infamous Allen slide. The majority of the climb is in the last 1.4 miles to the summit. The slide is steep and relentless. It does have a "red slime" which can be extremely slippery. Some hikers choose to wear microspikes to climb it. As you ascend enjoy moments to look back at the views. The summit itself is treed however, several short spur trails take you to some amazing views.

If you enjoy winter hiking this slide offers the best butt sliding experience in the Adirondacks (took us 1.5 hours to get up and 20 minutes to descend)!!

I do stress the majority of this hike is a herd path (unmarked and unmaintained). Please make sure you have map and compass skills.

I hike to push my limits both mentally and physically, take in the beauty of the great outdoors, and just to get away from it all. Every chance I get you will find me in the mountains, on a kayak or ending my day by the campfire!

There is three different trailheads to access the North Point Loop.  I chose the trailhead that would give me the longest hike.  That would be the Butter Hill parking area on Route 9W north.

Hike the Tongue Mountain Range

New York / Tongue Mountain Range Trailhead

The best way to tackle this hike is to spot cars.  I suggest the starting point for the Deer Leap trail, which is the trailhead location I chose coordinates for.  You will follow this trail for 0.
