Went on the most amazing hike on Cat Ba island to reach this peak! We were told it was a former US military base where they had telecommunication towers built during the war. It was an amazing site to see and I was glad to learn the history behind it as well . . . . #travelbook #travelpic #travelph #discoverunder5k #discoverearth #amazing_shots #amazing_earth #amazing_earthpix #travelawesome #lanhabay #lanha #halongbay #vietnam #travelvietnam #explorevietnam #agameoftones #agameof10k #sharpenmyfilm #vietnamtravel #outdoortravel #lumix #lumixambassador #gh5 #lumixgh5
