The Lamorinda Trail Loop has an interesting beginning. Initially the three communities of Lafayette, Orinda and Moraga convened a committee to look at connecting themselves via trails. However, upon looking closely at existing trails they discovered a trail route already existed through the three cities and they simply need to raise funds for signage along the route. After placing the signs designating the route the trail was officially opened on August 10th, 2006.
