Pomo Trail is a great alternative to the Panorama Trail
if you're looking to get out of the sun for a bit. It's well shaded with lots of Live Oaks and has a variety of small plants growing throughout, including lots of beautiful mushrooms during the intermittent wet seasons. Keep your eye out for a narrow gap to the north where you can look down onto a segment of Petaluma. It's best to have binoculars if you want to see much from there.
