A 20-foot gravel path is one of the most affordable options, with surface gravel, base preparation, landscape fabric, and edging included.

Flagstone is a premium option costing $200–$600 per ton, but the path will last 20–50 years with minimal maintenance.

A mulch path is the most budget-friendly option, though it needs annual replenishment. Edging helps keep mulch contained.
One ton of gravel covers approximately 80 square feet at 2 inches deep. For a 20-foot path that is 3 feet wide (60 sq ft), you need about 0.75 tons of gravel. Add a 4-inch gravel sub-base underneath for proper drainage, which doubles the gravel needed.
| Path Size | Surface Gravel | Base Gravel (4") | Total Cost |
|---|---|---|---|
| 10 ft × 3 ft | 0.4 tons | 0.7 tons | $30–$55 |
| 20 ft × 3 ft | 0.8 tons | 1.4 tons | $60–$110 |
| 40 ft × 3 ft | 1.5 tons | 2.8 tons | $120–$215 |
Mulch is the cheapest material at $30–$45 per cubic yard covering 100 square feet. Gravel and decomposed granite are next at $30–$50 per ton covering 80 square feet. Flagstone is the most expensive at $200–$600 per ton.
Yes, a gravel sub-base is strongly recommended for all path materials. A 4-inch compacted gravel base prevents settling, improves drainage, and stops weeds from growing through. Without a base, paths shift, sink, and develop puddles within 1–2 years.
A primary garden path should be at least 3 feet wide for comfortable single-person walking. For two people to walk side by side, aim for 4–5 feet. Secondary or decorative paths can be as narrow as 2 feet. ADA-accessible paths require a minimum of 4 feet.
Material longevity varies dramatically. Mulch paths need replenishing every 1–2 years. Gravel lasts 5–10 years with occasional top-up. Decomposed granite lasts 3–7 years. Pavers and flagstone last 20–50 years with minimal maintenance.
| Material | Lifespan | Maintenance | Best For |
|---|---|---|---|
| Mulch | 1–2 years | Annual replacement | Budget paths |
| Gravel | 5–10 years | Occasional top-up | Casual walkways |
| Pavers | 20–30 years | Minimal | Formal paths |
| Flagstone | 20–50 years | Very low | Premium gardens |
