As noted on the main page, the easiest way to Ehrnbeck is to start at the Twin Lakes trailhead detailed in the "Getting There" section.
Depending on desired objectives (such as multiple peaks in a day), the exact route from Peeler Lake to Ehrnbeck will vary. Cross-country travel will be mandatory starting at Kerrick Meadow or Buckeye Pass. Work over ridges and up slabs to the sandy East Slope. Head directly for the blocky knob-like summit block, climbing it from the south side.
Refer to this map for additional information.
Summertime climbs will warrent sticky approach shoes to make the miles of slabs enjoyable. Fortunately, water is plentiful in this area, so carry a filter for frequent refills.
Out of season climbs will likely require ice-axe and crampons to negotiate the steeper sections covered in snow and ice.
If you have information about this route that doesn't pertain to any of the other sections, please add it here.
