FATMAP difficulty grade
Start at old Chisenupuri parking lot.
It is the large lot on the left just before the hot springs on your left off of Route 66.
You know you have gone too far if you reach the intersection of Route 66 and Route 58. This is a very straightforward ascent that is recommended in fair weather, as the gem of this route is Chisenupuridake itself, rather than the lower terrain that makes up the old ski resort.
That said, there is some rather exciting and enjoyable terrain located in the old resort if it is a storm day. From the parking lot, follow the dominant track up the piste to the climbers left.
This will wrap around slowly to the top of the chairlift.
One of the nicest things about this route is that it is popular and one will frequently find a skin track that leads through the woods.
There is a cat skiing operation in this area, and it is possible to catch a lift with them to the top of the old ski resort, saving a fair bit of effort. Once on top of the old resort, enter the trees heading N/NE towards the main mountain.
You will be climbing the S rib, or the SW face, depending on snow coverage and conditions.
Though you will be able to see exactly where you are going, do not be deceived, as the hike is farther and longer than it appears.
Budget at least an hour and a half to reach the summit.
Be cautious at the top.
This peak is close to the ocean, and gets a lot of wind.
There is frequently rime and ice on the upper portions of the climb that can make skinning very difficult. As with many of the other volcanoes in the area, be wary of holes that form due to wind or snowpack creep.
Resist the temptation to climb the SE face as this is frequently skied and is prone to wind loading near the top.
