We are a gathering of thinkers, doers, artists, dreamers, muckrakers, and builders interested in life on the water.

We construct a floating city on the Sacramento River Delta at Mandeville Point and live on it for seven days.

There are no tickets, no central organizers, no rules, and no Rangers to keep you safe. You must practice radical self-reliance, if you want to have a good time.

What's it like to attend? Here's a slideshow from past years of Ephemerisles. Also see Judd Weiss's pictures from Ephemerisle 2014.

Since there's no central organizer, the event only happens if people contribute.

After lively discussion in 2012 about the values that connect Ephemerislers as a community, the following received broad support:

Ephemerisle 2017 will take place during July 17 - 23.

Before anything else, PLEASE READ THE survival guide!! The Survival guide contains important "how tos" and information on having a fun, safe time.

Ephemerisle events are listed on the What, Huh, Whoa spreadsheet:

The Facebook group can sometimes have an overwhelming amount of discussion. Join the Ephemerisle Announcements Only mailing list to receive important announcements.

Here are the dates for future years.

Here's a few things you can do: bring art, give talks, build your own boats and platforms, rent a truck and help carry floating platform parts, build illumination, make music, bring a wakeboard, and help build this wiki.
