You will need a kayak, canoe, SUP, or small shallow draft boat to find this cache!
You will probably need to disembark and go ashore on the small sandy beach to reach this cache. It should be findable at high or low tide.
I paddle here several times a year, and am finally getting around to hiding a few caches. This is a great area for kayak, canoe, or SUP. I frequently see cormorants, ducks, blue heron, and deer, and I've occasionaly seen a bald eagle here as well. Solleys Cove Park features a soft launch with drive-up access for loading/unloading, as well as a conventional boat trailer ramp. There is no fee to park or launch here, and a port-a-potty is available. There is plenty of parking, but it can get busy on weekends in-season. It's almost always quiet on weekday mornings, when I typically visit.
These caches are hidden along Marley Creek, south/upstream of the launch. Along the way, you will pass Tanyard Cove, where there are several more caches to find. If you are hungry afterwards, you can cross the channel to Furnace Creek, where there are a couple of restaurants with paddle-up access.
I hid Marley Creek #6-#10 at just past high tide, on a morning that turned out to be much windier than forecast. As a result, one or two that I had intended to be "float and grabs", I ended up disembarking to hide instead, just to give myself a break during the upwind paddle back to the launch.
