secluded
Quiet and private, hidden away from other people and noise.
Secluded means hidden away from others, private and separate from the busy world around you. A secluded beach might be tucked behind cliffs where few tourists ever wander. A secluded cabin in the woods sits far from roads and neighbors, surrounded by quiet forest.
The word suggests peaceful isolation rather than loneliness. When a family finds a secluded spot for a picnic, they've discovered a place where they can relax without crowds or noise. A secluded reading nook in a library offers privacy for concentrating on a good book.
Secluded places feel protected and apart. A monastery might be built in a secluded valley where monks can focus on their studies and prayers. Writers sometimes seek secluded retreats where they can work without interruptions.
Something secluded isn't necessarily locked or forbidden, but it's set apart from the main activity. A secluded garden behind tall hedges, a secluded corner table at a restaurant, or a secluded trail that few hikers know about all offer a sense of privacy and escape from the usual hustle and bustle.
