The Daily Otter has posted lots of sea otter photos taken at Moss Landing. One of this video's YouTube commenters, apparently a marine biologist, says:
Its a great experience! The otters in the slough have been fed by so many humans that they'll swim up to your kayak and "play" with you to try to get free food. I've observed it myself. Some of the more adventurous otters will actually climb onto your kayak.
