You may see people feeding them but I recommend to not do it! It is illegal and it makes the sea lions dependant on humans for food and they get lazy to find fish on their own. There are big fines for feeding them although this is not strictly enforced.
Your are welcome to walk along any of the docks and talk to the fisherman take photos of the boats but be careful not to slip walking down the ramp. There are grips on one side of the ramp but the metal side can be slippery when wet. Also kids under 12 have to have an Adult with them.
Kodiak and Near Island were hit by a tidal wave after the Good Friday Earthquake of 1964. This is a real danger. Get to high ground. I don't know if you should cross the bridge, but there is higher ground on the other side. Meet at my house, it is above the "safe" zone.
While you want to see all the animals remember that they are wild, and you should not disturb them. Many are protected. Do not Feed, or try to touch them.
