Denver Botanic Gardens
1007 York St., Cheesman Park
Located adjacent to (and really a part of) Cheesman Park, the botanic gardens are nestled into one of Denver's nicest and most historic neighborhoods. The gardens themselves are a perfect combination of locally inspired (the Gardens of the West are inspired by Colorado's arid landscape and the hardy plants that evolved to thrive here) and lusher, more ornamental gardens that typify classic gardens anywhere. There are plenty of magical little pockets to explore, and it's particularly beautiful to visit at night. In the summer, they host a live concert series in the round on their largest lawn—arrive a bit early so you can set up a picnic and a lawn chair near the stage.
