Denver travel tips
Despite the location near mountains, Denver is pretty flat to ride a bike. The only two areas that may give bikers problems are the Highlands and the Cap Hill, with their steep slopes and hills. But generally, you can ride a bike around the city without worrying about a 30-degree incline.
Rent a bike with a bike-share program, B Cycle, in Denver. A perfect place to start your ride is Sloan Lake with its big surrounding area.
When you see the 7-meters-high dairy jug in Denver, just know it is Little Man Ice Cream cafe. They sell cones of handcrafted ice cream, including vegan options. A classic Chunky Chocolate cone is a must.
