Adding gravel around your fire pit can create a dramatic seating area as well as serve a structural purpose. However, the rock fragments you choose do play a vital role.
Rocks are also often used inside fire pits to help distribute heat, but the most popular varieties of gravel should not be placed inside them for safety reasons.
Some popular choices include crushed limestone because it drains and compacts well and pea gravel, which needs to be regularly raked since it shifts and doesn't drain as well.
There are also eco-friendly, stylish alternatives to gravel in fire pit landscapes, such as crushed shells from clams and oysters, crushed bricks, silica sand, and recycled glass.
