North Halfmoon Creek Trail #1485 (Mount Massive)

Area Status: Temporarily Closed

North Halfmoon Creek Trail #1485 is a steep 3.4 miles (one way) trail with 3,950 feet in elevation gain that takes visitors to the North Halfmoon Lakes. At the 1.4 mile mark, the trail will fork and become the South Mount Massive Trail #1451. This trail is 1.9 miles long and will lead to the summit of Mount Massive.

The last ½ mile of the road to this trailhead requires high clearance and 4WD and should not be attempted with a passenger car. Park cars at the road junction ½ mile before the actual trailhead and walk up the rocky road. This is not an easy hike – from the lower meadow to the summit there’s nearly 3,300’ of elevation gain in 2.5 miles.

General Notes:
  • Mountain weather is unpredictable and can change quickly. Be prepared with rain gear and extra layers of warm clothing. Always check the weather forecast before heading out.
  • Thunderstorms occur frequently in the afternoons, so plan your trip accordingly. Also, keep in mind thunderstorms build rapidly, so keep an eye on the weather and get below timberline at the first sign of a thunderstorm. Follow these Lightening Safety Tips.
  • Combat altitude sickness by acclimating gradually and staying hydrated. If symptoms (i.e., severe headache, dizziness, or nausea) do occur, immediately descend to a lower elevation.
  • At high altitudes, sunlight is much more intense and the air is much drier. Wear sunscreen and a hat, and drink plenty of fluids. Always carry a map and compass and know how to use them.
