Maybe 4 minutes total. You park in a grassy field as directed by the lifeguards. Then walk 3ish minutes to a place where you pay the remaining balance and get a life jacket. (If you get there early then you are a 1 minute walk.) Then another 1 minute walk to the quarry. You can rent a table in the shade for $15 or set up your chairs and umbrella in a grassy area.
A relatively short walk depending on where you park. It's not handicap accessible (at least not from what I saw). Once inside the quarry area, it is a steep hill down to the grassy area where people sit.
