5.58 mi

Start at the Little Si parking lot. Follow the Little Si trail for about a half mile and take the Boulder Garden Loop to the right. Stay on the Boulder Loop for about a mile. Old Big Si trail will be on your right. Old Big Si trail comes out about a half mile from the top (boulder field) of Mt. Si. Make sure you make a visual/mental note of where the Old Big Si trail meets up with the Mt. Si trail because it is easy to miss the trail when you are coming back.
