In Golang, there are several ways to declare variables:

1. Using the `var` keyword:
   ```go
   var a int
   var b string
   ```

2. Declare and initialize variables:
   ```go
   var a int = 10
   var b string = "Hello"
   ```

3. Short variable declaration (only usable within functions):
   ```go
   a := 10
   b := "Hello"
   ```

4. Declare multiple variables:
   ```go
   var a, b, c int
   var d, e string = "Hello", "World"
   f, g := 123, "Hello"
   ```

When choosing a declaration method, consider the use case and code readability.
