Because of its size and location it s a great place to see the nights sky!

~1 Hour Drive Away: Pacific Lake

This is a hidden gem that is a 1 hour drive from the Moses Lake area provides a great opportunity to see the night sky. Pacific Lake used to be stocked for fish before water levels became too low for sustaining fish life. Being so far away from cities and other tourist areas make the lake an ideal place for viewing the night sky and not see others for an extended period of time.
