Platinum Peak, located by the Crystal Mountain Ski Area is home to amazing views of Mount Rainier and neighboring peaks. The mountain itself located to the east the ski area is a great winter destination provide avalanche conditions are very low. The views from this summit in winter are breathtaking on a decent day with nearby Mount Rainier showing its dominance and Mount Adams dominating the skylight to the south. Even Mount Stuart to the northeast can come into clear view from the summit of Platinum Peak. The view from the summit of Platinum Peak as well as its close proximity to the ski area and low amount effort for the great summit (6 miles; 2500 feet of elevation gain) makes this mountain a wonderful peak to go to.
The best way to reach Platinum Peak is from Bullion Basin. When you arrive at the ski area, walk to the left (east) of the main lodge. From there take a number of roads up to the Bullion Basin Trailhead. Once on the trail take the Bullion Basin trail all the way up to Bullion Basin which is at the elevation of 5800 feet. From there make the YDS 2 snow climb/bushwhack up to the summit. Be aware in winter you will be crossing open 45 degree slope that could become hazardous in high avalanche danger. Try to go straight up from here if safe. Going to the ridgeline and then traversing to the summit in winter caused me traverse an even steeper avalanche slope where a slip could cause a fall of over 800 feet. If climbing this peak in winter, an ice axe, traction devices and snowshoes are absolutely required. You will encounter steeper slopes and variable snow conditions even on the best of days. Once on the upper, more level section of Platinum Peak, head directly to the summit where terrific views await.
