Hey Matt,
PM me if you'd like to discuss diving together at Langley. I'll show you the entry route. I'm still slow at gearing up and catching my breath so I'm plenty patient for others. I'm generally available on week days too.
Basically you go off the end of the boat ramp but have to head N.-ish to your left and go under the pier, N. of the pilings to submerge.
At the shore end it's standing depths generally, so you can lean on a piling to put fins on etc.
This route takes you past the point where you might swim into the marina which is
dangerous and strictly forbidden. You'll see the Western end of the vertical log breakwater ahead of you. You can surface swim to it and descend there traveling E.
along the wall. (Depths approx. 15-20ft. here.) At the end of the wall, the tire reef
will become visable and you follow it around to your right heading S.-ish.
Depths on the reef are around 30-45'. Be careful to watch for the tire reef's southern end. Once past it you are in the marina/boat traffic area. Listen for boats
before ascending at Langley. It's a tiny rural marina so there is very little traffic most of the time. I haven't been there in late spring or summer though...
The only thing that may "throw" you a bit on the tire reef is that there is a "cut" or path between two parallel tire reefs which you may swim "into". Just come back out the same way or if the ambient light is good (generally is with a reflecting sand bottom) you can swim over the top of the reef to the "other" reef and head S.
Good beginner site. Easy to surface if you feel disoriented. No current to deal with. Good place to practice basic compass skills like reciprical couses, etc. because natural navigation clues are ample to check yourself against the compass.
(I did my Nav. class here a year and a half ago, and I was so tuned into my compass that I completely forgot to register natural navigation landmarks
I had to go back for another dive so I could actually see the site!)
There can be "some" current here but it's never been more than a very very gentle drift that can be easily swum against. Often there isn't any noticable current.
The biggest problem is that the viz can vary from poor to great. There is a halocline here at times that you have to dive under to get better viz. I think even in horrible viz, diving along the wall you can get close enough to enjoy critter viewing and practice nav skills, buoyancy control with a visual check (the wall), etc.
A good hose rinse off area and bathrooms help too.
