Also read the trip reports and planning info on wta.org. they have tips and fee information.

Yes! Check the tide charts and plan accordingly. Pro tip, bring ear plugs. When I went the wind was blowing pretty hard for the hours I hiked it and that plus the sound of the waves really started to fatigue/hurt my ears by the end (it was like being in a wind tunnel for 4 hours). It's a lot of fun though and a really unique hike. Get a snack/coffee at Sunny Farms on your way out. Have fun! :)
