Experience this annual spectacle of light from the water on "Petaluma's Longest Park", The Petaluma River. Just show up at The Floathouse (summer location: access via public docks on the NW side of the basin by Water Street/Balshaw footbridge). We'll have the boats ready to go, and you and your friends simply step aboard, joining in a joyous flotilla, paddling to prime viewing spots, marveling at the illumination in the dark night sky and reflected on the water. $50/person. Limited to 20 guests. Book here.
