This road starts as gravel but turns to pavement, but it is unlikely that you'll notice as you are gasping for air on the areas largest climb. Head past the turn for Old Rico Road
which would continue the Dirty Sheets Gravel Loop
in order to return to the parking area.
Access free parking for night rides starting from Serenbe. Peachtree Bikes also operates a weekend store in Serenbe if you need to grab a tube or other quick supplies.
