There is a large pay lot at the beach park--just pay for as much time as you want--like a meter that spits out a ticket for your dash. The walk is maybe 50-75 yds. from the lot, 150+ if parked on PCH. For kick boat or float tube launching it can be hairy--it's where I got flipped in mine two months ago and it was a small day. The shore break can be nasty. I have successfully launched there in the past, I guess I was due. Most of aliso is pretty exposed to swell except the far north end which is a 1/2 mile walk--a south swell will go into there as well though. For KB or FT outings you might want to try one of laguna's coves instead as they are more sheilded. Each one is different depending on season/sand coverage and swell direction.

BTW, I think you wear waders for your harbor outings, not sure...anyway, if you didn't know this already, NEVER where them in open water like a surf beach. You are asking for trouble. Only wear a wetsuit or just trunks as waders can fill if a wave crashs on you or you get flipped.
