Thousands of partygoers are planning to attend a beach party on Friday the 13th next week, but police and parks staff say they’ll have to get past their officers first.

The “full moon beach party” Facebook page has logged more than 7,000 “I’m going” hits for a party planned for June 13, the night of a full moon.

The site says it’s organized by DJ Bjorn, a Swedish DJ who now lives in Vancouver and whose website says he parties at his favourite beaches on English Bay, in Kitsilano and on Wreck Beach, wearing a costume and carrying his portable DJ equipment with him on his electric bike.

“Day time is almost always at English Bay and we also set up for after-hours (starting at 3 a.m.), but those locations are kept secret till the very night,” he wrote on his blog.

He didn’t return messages and the Facebook page doesn’t include a location for the full-moon bash, but a number of the entries guessed it to be Wreck Beach, Vancouver’s tolerated clothing-optional beach near the University of B.C.

RCMP’s UBC detachment said they’ll be ready if the thousands who promised to show up arrive at the beach, notorious for open drug and alcohol use.

Police officers and park rangers from Metro Vancouver Parks, which runs the beach, will be positioned at the four marked trails to the beach, which is at the bottom of a steep embankment accessible by 472 steps.

“It is a contravention of a (Metro) Parks bylaw for anyone to access the beach after sunset,” said UBC RCMP spokesman Sgt. Drew Grainger, who said the embankment would be treacherous in the dark.

He said ticketing and arrests are possible but officers would prefer to make a “public service announcement” to anyone attempting to access or remain on the beach after dark.

Damara Smith said she learned of the event from a friend on Facebook. The Richmond woman said she’s never been to anything like the advertised event before, but had imagined it’d be similar to the annual fireworks held at English Bay, “but with more music and not as many people, like a cool outdoor, nice setting.”

“I looked into it and thought it looked like a neat idea, so I said, ‘Yes, I’ll go,’’’ said the 27-year-old.

Vancouver police said their regular beach patrol is always on the lookout for violations of park bylaws and liquor offences.

“In the event that an incident is brought to our attention that is beyond the scope of the beach patrol, our emergency operations and planning section will work to ensure that sufficient resources are available,” said Vancouver police Sgt. Randy Fincham in an email.

UBC RCMP find after-hour partiers on the beach about once a month, as they did about a month ago when they learned about a rave that had been advertised on social media.

“We go down and we ask them to abide by the park closure,” said Grainger.

Smith said she wasn’t too worried about safety concerns such as open liquor consumption and drug use.
