The 25-year-old started all three Tests Down Under and admits that his body was in need of some rest before throwing himself back into action with his Welsh region.
"It' been a bit of a crazy summer in rugby to be honest and looking back I realise why I really appreciated Simon Easterby giving me a decent break once I came back from the Lions tour," Davies told the South Wales Evening Post.
"It was such an intense season, culminating in a semi-final place for the Scarlets in the Pro12 then into my first British & Irish Lions tour.
"As a player these are moments in your career you don't forget but after a good break and some time away, I feel really refreshed and looking forward to getting started again.
"I took a lot from the tour just in terms of experience - seeing how some of the most senior players led in terms of their work ethic and their knowledge and how they would input into the campaign."
