e.GET("Error404", func(c echo.Context) error { return ... })

you never need to set up a router of not found error, it's a status of requested page

package main

import (
    "net/http"

    "github.com/labstack/echo"
    "github.com/labstack/echo/engine/standard"
)

func main() {

    echo.NotFoundHandler = func(c echo.Context) error {
        // render your 404 page
        return c.String(http.StatusNotFound, "not found page")
    }

    e := echo.New()

    e.GET("/something/:id", func(c echo.Context) error {
        if c.Param("id") == "5" {
            return echo.NotFoundHandler(c)
        }

        return c.String(http.StatusOK, c.Param("id"))
    })

    e.Run(standard.New(":8000"))
}

also see default error handler https://github.com/labstack/echo/blob/master/echo.go#L276, you can customize it setting own error handler using e.SetHTTPErrorHandler

You Can also pass error URL Name. like
echo.NotFoundHandler = func(c echo.Context) error { user_input = c.Request().URL // http.URL msg = "not found page :" , user_input // render your 404 page return c.String(http.StatusNotFound, msg ) }
