Parking can be found at Lake Union Park (860 Terry Ave N.) at the southern end of the lake, as well as at Gas Works Park (2101 N. Northlake Way) on the northern end.
The Westlake side is being upgraded to have actual bike lanes that should be completed before the summer of 2016. The Eastlake side makes no accommodation for bikers and is one of the more dangerous rides around. The best thing to do is to stay off Eastlake as much as you can and travel along the streets nearest the lake. You will have to ride up a couple blocks away from the lake at one point, but most of the trip can be had along the lake side.
