The small larch forest and the scattered larch trees on the way to Frosty Mountain attract many people here every year, especially in autumn. Also known as Mountain Monarch, you will find a very special tree species here, the alpine larch. Some larches are over 2,000 years old. They are especially beautiful to look at in the fall, when they change their green leaf dress for a bright yellow one.

Once you've fought your way up here, a spectacular view of Frosty Mountain and the surrounding mountain landscape awaits. Especially in the sunshine, you can stand it here for a few moments, provided you don't come here in high season, because there's not much space at this crossing. To the actual summit, it's only about 600 meters in distance. However, as it goes over the ridge, it can be dangerous in winter with snow. Then it may be enough to enjoy the view from here.

The climb from the west is not as steep and arduous as from the east and is the classic walking direction if you hike the loop. Also, you can spend a night at Frosty Creek Camp at about 1,900 meters and climb the summit at 2,400 meters the next day. To spend the night in the backcountry, you'll need a permit that costs 5 dollars a night per person. Also note: In winter and even in fall, Frosty Mountain can be snow covered. So if you are descending to the west, you should have microspikes in your backpack for this case.

If you come all the way from the Mexican border this is where your epic journey along the 2,650 miles of the Pacific Crest Trail ends. It might also be the start of your adventure if you chose to hike the National Scenic Trail southbound. It is marked with a wooden pillar monument a little south of the international boundary marker to Canada called Monument 78. As of January 25, 2025, the Pacific Crest Trail permit program to enter Canada has ended. You are only allowed to enter Canada using a designated point of entry. On the United States side, the nearest road to pick up a hiker is Hartโs Pass Road (usually passenger-vehicle accessible) which is a hike of around 30 miles south from the northern terminus. As getting to and from the northern terminus is not that easy since there are no roads, here are some helpful tipps for logistics and maps: https://www.pcta.org/discover-the-trail/backcountry-basics/pct-transportation/directions-northern-terminus-pct/
