Biking enthusiasts can explore the park's six-mile multi-use trail. Be aware, it is shared with hikers and horseback riders.

The terrain varies from flat to moderately steep hills, so caution should be exercised when navigating these trails.

While biking at night isn't prohibited, remember that lighting conditions may affect visibility on certain parts of the path.

For those seeking a leisurely ride or family outing, consider sticking to flatter sections for an easier experience.

Remember always wear helmets while cycling; safety first!

Please note: The weather in Missouri can change quickly - check forecasts before setting out on your bike adventure.

Lastly but importantly! Respect wildlife you encounter along your journey – keep distance and do not feed them.
