Captain Wendy built a beautiful electric boat - perfect for comfortable, quiet, gas fume-free touring of the slough. She and her guide Wyatt were knowledgeable and friendly - we learned a lot and felt very well-taken-care-of. Saw so many otters! As well as seals, cormorants, herons, pelicans (a rare white one!) etc. Fun to watch the otters eat, play and groom their pups. Highly recommend this tour.
