Pfeiffer Beach

I went here back in December 2017 and the violet sand was available at some spot towards the back of the beach,. You just have to walk around and find it. It's not much.

They do have bathrooms in the parking lot, but they aren't pleasant lol. Depending on the season, there are a couple of freshwater streams that run across the beach.

Yes

Still open

Pfeiffer beach you can drive to but some times it gets full quick but its worth the wait. We waited about 30 minutes before we could get down there but once you get down there its 12.00 dollars to park and yes they have purple sand on this beach. I have posted pics its amazing and worth the wait. Theres moonstone beach also they have large chuncks of jade but you have to dig for them. We got two hugh bags full.

Doubt it. I'm not even sure you could get an RV down to the parking lot. It is a very tight road

Im not sure if fishing is allowed since it is a park, but there are some rocks a little down the beach that you can climb onto and cast your line. The currents are really rough so fishing probably isnt that great. Hope this helps.

Im no beach authority by any means, but I don't see why it'd be closed!
