Grass arenas provide a natural and soft surface for horses, but they require more maintenance and can become slippery when wet. Sand arenas are low maintenance and provide good traction, but they can be hard on a horse's legs and may require more frequent grooming. Ultimately, the decision should be based on the specific needs of the riders and horses, as well as the climate and resources available for maintenance. **

Consulting with a professional arena builder or footing specialist can help determine the appropriate depth for your specific needs. **
