The Hike:

After parking in the dirt parking lot, locate the trailhead sign and begin hiking on the trail to the left:

The start of the hike is fairly easy and begins in a heavily wooded area. Don’t be fooled though; the trail quickly begins to make the ascent up the mountain. It may not appear so at first, but this trail is extremely steep.

Note: There are three major “points” of the trail; The Two Sentinels, Martin Point and Glove Rock (more information below).

Continue through the forest, following the dirt path. Eventually the forest line breaks and a column of solar panels comes into view:

After about 2.5 miles in, the first point, called Two Sentinels, is reached:

Continue along the ridge until the second point, called Martin Point, is reached (this is the view of Martin Point looking back):

There are many skiing warning signs along the ridge (this is a popular skiing area during the winter months), as well as a trail marker:

At the 3.2 mile mark, the final point before Thunder Mountain is reached, which is called Glove Rock. Continue hiking on the dirt trail to the backside of Glove Rock:

After continuing on the trail towards backside of Glove Rock, a fork in the trail is reached at 3.7 miles. It is marked by the following sign:

Stay to the right of this sign to continue towards Thunder Mountain. The dirt trail eventually turns into a rocky scramble to the top of Thunder Mountain. Keep an eye out for the trail ducks to stay on track. After about a half mile, Thunder Mountain is finally reached (Silver Lake can be seen to the left):

Take the same trail back down the mountain towards the trailhead. Enjoy the views!
