Denver sits at ~5,280 ft above sea level (mile high city!). Alcohol hits faster and basic tasks/exercise can seem more effortful. Please pace yourself and stay hydrated! The sun is stronger so keep sunscreen/hats close.
Downtown is easily navigated with public transportation, but for surrounding neighborhoods, Uber/Lyft is your best bet.
The open or public consumption of marijuana is not allowed. However, smart and discrete vaping is tolerated. Edibles, while strong, are your safest bet for consuming in public. Please keep in mind this isn't your uncles hash and it's pharmaceutical grade strength packs more of a punch than you might be accustomed to.
If you are flying in/out of Denver and do not have TSA Precheck or Clear, you can reserve a spot in the security line for your departing flight. This can be scheduled up to 2 weeks in advance. Please visit Denver International Airport website for more information.
