A gravel garden path is one of the easiest and most affordable landscaping projects. A 20-foot path at 3 feet wide needs just 10 cubic feet (0.37 yards) of decorative gravel — easily managed with bagged stone from a garden center.
Best Gravel for Walkways
| Stone Type | Size | Best For | Cost/Bag |
|---|---|---|---|
| Pea gravel | 3/8" | Smooth, comfortable walking | $5–$8 |
| Crushed granite | 1/4"–3/8" | Packs firm, stays in place | $5–$7 |
| River rock | 1"–2" | Decorative, zen gardens | $7–$12 |
| Decomposed granite | Fine | Most walkable, compacts well | $4–$6 |
Installation Steps
- Mark the path with garden hoses or string for curves. A 3-foot width accommodates comfortable single-person walking.
- Excavate 3–4 inches. Remove sod and topsoil to create a shallow trench.
- Install edging. Metal, plastic, or stone edging prevents gravel from migrating into the lawn. This is the most important step for a path that stays neat.
- Lay landscape fabric to prevent weeds from growing through the gravel.
- Pour, spread, and compact. Spread gravel evenly, then tamp with a hand tamper for a firm walking surface.
Pro Tips
- Decomposed granite (DG) is the most walkable option. It compacts almost like dirt but looks manicured. Add a stabilizer binder for wheelchair/stroller accessibility.
- Skip river rock for main walkways. Beautiful to look at, but the round stones roll underfoot and are uncomfortable to walk on. Use river rock for decorative borders instead.
