If doing Langley as a multi-day, check with the VC for any permit requirements. Have done Langley many times, always as a dayhike, and have been stopped a couple of times near a lake and asked if I was planning to spend the night. It's been a few years since I've done Langley, so don't know if the overnight permit requirement is still in place.
In the interest of clarity - if doing Langley as a dayhike, am quite sure you DON'T need a permit.
