Mountainboarding is an outdoor sport that combines elements of snowboarding and skateboarding. Participants ride on a board with large, inflatable wheels designed for rough terrain, such as hills and trails. The sport can be enjoyed on various surfaces, including grass, dirt, and gravel, making it versatile for different environments. Riders use their body movements to steer and control the board, allowing for tricks and jumps similar to those seen in skateboarding. Mountainboarding can be practiced recreationally or competitively, with events often held in locations like mountain resorts or off-road parks. Safety gear, including helmets and pads, is recommended for protection.
