Lea was pictured yesterday (3 September) looking reflective as she relaxed in a shaded wooden cubbyhole while taking in the beautiful scenery around her.
Laying back with her arms gently folded, the actress gazed out at the vast landscape of trees, lakes and hills while a friend took the stunning photograph.
Lea – who had headed to the mountains for an American national holiday - then posted the snap on Twitter, telling fans: "Enjoying this Labour Day tucked away in the mountains, breathing in the fresh air! Have a beautiful day:)"
In July, Lea's boyfriend and fellow Glee star Cory Monteith was found dead in a hotel room in Vancouver, Canada, following a drink and drugs overdose.
Lea has since bravely returned to work and on 11 August she made a heartfelt and emotional tribute to Cory at the Teen Choice Awards 2013.
"I just wanted to be here today to personally thank all of you and tell everyone out there how much all of your love and support has mean to me over these past difficult few weeks," she said.
