One of the most convincing reasons to keep reading the Chronicle is Tom Stienstra whose recommendations for outdoor Bay Area ventures are unassailable. He is a big fan of a hidden gem called Soulajule Reservoir 15 miles north of Novato. This despite the facts that there are no real hiking trails, no camping, no drinking water, no restrooms, no boating and no swimming. But you can meander along the shoreline, have a picnic, fish for bass and soak in the quiet splendor of Marin at its most magical. Leashed dogs only.
