The mountain can be reached through multiple established hiking trails with various access points, and parking is available at the main trailheads. Plan your visit by choosing a route that matches your fitness level and allow enough time for the elevation gain.

The mountain's location creates specific microclimates that support rare plant species found only in this region. These special climate conditions enable the growth of vegetation that exists nowhere else in the same form.
