    "The is a disc golf course nearby. It isnโ€™t far from downtown. It isnโ€™t far from a great dispensary. The breweries are only a short walk. "

    "ive been vistiting my family out here and I just love the neighborhood โค๏ธ so welcoming super clean been really wanting to move to Longmont "
  • annette e.
    "I have lived many places and have never had as many friendly (without being overbearing) neighbors as I have here. It is a safe, family-friendly neighborhood with easy access to all surrounding areas, but without traffic noise. "
  • Teresa S. h.
    "I've lived in this neighborhood over 20 years. It's a quite area, city bike path is only one block away. Elementary school is 4+ blocks away, easy walk or ride bike. City park (near school) has basketball, softball field and well lit. Plenty of open space to let the kids and pets run, fly kite or have a picnic. Overall folks are friendly and say hi."
  • annette e.
    "A real neighborhood with great neighbors! Close to shopping, park, churches, school."
  • shinyshinystar
    "Sprawling lawns and large, well-kept homes line the meandering, tree-lined drives. Families and couples can be seen walking their dogs, enjoying one of several area parks or exercize paths, and the crickets chirp in the fading light, giving way to a calm, community quiet - a peaceful and safe neighborhood - where each home boasts its' own unique ambiance through charming paint colors, various and impressive gardens, and individual decor. Everyone here knows one another, keeping the area nearly inpenetrable from crime or outside traffic, and you can tell the people here take pride in this beatuiful, affluent community. Many wonderful memories are waiting to be made for any couple or family who chooses to live within it's safe boundaries. A VERY underrated section of Longmont, close to the charm of historic downtown, yet literally one minute (in the car) from the modern conveniences of the stores we all depend upon, such as grocery stores, Target, etc. This is a truly charming, yet upscale community, with some of the most welcoming, friendly people Longmont has to offer! "
  • Hiskeyco
    "Live here. Very quiet, beautiful area with mature landscaping, and good neighbors. "
  • Boulder S.
    "There are many great finds in this neighborhood, particularly if you like the charm of this architecture. Many of the homes in this area have been restored or enlarged. The attraction is the walkability, shops and restaurants. Longmont's nightlife is fun, too. The library is only steps away. The area is great for active people who jog or bike. Traffic is more than tolerable. There is some slow going around highways 287 and 119 around rush hour - but nothing compared to metro areas. "
