The Tom Rock Gravel loop is classified as a 'difficult' ride due to significant elevation changes and potentially rough or steep gravel surfaces. While gravel bikes with wider tires (40c or greater) and low gearing are recommended for such conditions, traditional touring bikes with heavy loads might find this loop particularly demanding.

Always check local signage for parking regulations.
