Coming in from NYC 7/20 - 7/23: Looking to go to Rooster Rock

Hello Fellow TrueNudists:

I'm staying in Portland from Wed 7/20/22 to Saturday 7/23/22. I have Saturday free to myself and would love to check out Rooster Rock. Any advice on mass transit to get there from the city center? Ride shares? It'd be a great bike ride but I have such limited time, I'd like to spend most of it on the beach not on the bike.

Thank you in advance for any suggestions you have!

Cheers,
Jay
