I dropped by several launch sites y’day. Each is feasible but has its pros and cons.
toilets are lacking at all of these launch sites except Whytecliff.
Stearman Beach and Erwin Park are ok but if there’s a E wind there could be waves. There are some steps and obstacles. for a small group at this time of year parking will be adequate.
Caulfield Cove is super protected and parking should be ok even if there is a church service at 8 am. Access across the grass and a few rocks is easy enough. This gives us the chance to paddle twice around Pt Atkinson!
Eagle Harbour is also very protected and has a super smooth sand beach. It would have deluxe flush toilets if W Vancouver munic were to unlock them. Parking should be ok.
Batchelor Cv has a prupose built canoe/kayak skid but I have yet to see anyone use it. You first have to move the drift log at the bottom. Parking is good. There could be wave action on the beach in a W wind and there are big cobbles, almost boulders at low water.
Whytecliff Park. Lovely, but a longish carry from the cars and the beach can have lots of drift logs and waves.
My vote is Caulfield followed by Eagle. What’s your preference?
