Miami is flat as a pancake, a place where having a mountain bike is kind of like having snow skis. But the Grove Skate Park is proof that man can make mountains out of wood and steel. For $10 on weekdays and $13 on weekends, you can roll through 10,000 square feet of perfectly constructed transitions, including a 28-foot-wide miniramp, quarter pipes, a beginner's course, and other obstacles for the brave bike rider. The skate park is located in Coconut Grove's beautiful Peacock Park, where there are also less-dangerous nature trails to explore (as long as you don't ride over a sleeping homeless person). Because the skate park gets mobbed on weekends with young skateboarders, we recommend mountain-biking there during the week, when it is usually empty. After riding around the wooden ramps and obstacles, cruise through the Grove. There are trails that lead toward the bay or in the opposite direction, toward the bars.
