Columbia and the surrounding area has the best trail system! There are many neighborhoods that allow one to just get on foot or on your bike and not only get great exercise, but enjoy doing so with an amazing view on an amazing trail. I know I do!
You'll see many people of all ages doing the same. Families with children in strollers, people training for triathlons, people casually walking by themselves or with others, and people walking or running with their dogs. You'll go by Twin Lakes, where you'll find a dog park, swimming area, and fishing area. You'll find access to downtown's Flat Branch Park and District. Personally, I love it! It's free. It's invigorating. It feels happy and it's easy.
If you're a wine-lover, you'll love riding to the winery in Rocheport. You'll enjoy the bluffs along the Missouri River. It's a soft and warm approach to really living in your neighborhood!
