TLDR: Beautiful, calm, area unique, beware allergies.
The Denver Botanic Gardens are a beautiful Denver classic. Every local I've spoken to recommends the trip. You can spend several hours there, get food, and enjoy plant life from all over the world. If you're allergy prone like me, take something before you go or you'll find out what it's like to have a running nose and sneeze in 7 different biomes.
