The Willamette Valley Grotto is a non-profit organization whose purpose is to further cave exploration, conservation and preservation. The WVG is a chapter of the National Speleological Society.

Members of the grotto participate in recreational and scientific cave trips, as well as surveying, mapping and exploration. We have camp-outs at caves, some requiring a bit of backpacking to reach. Caving encompasses a broad range of skills ranging from crawling to climbing. Some cavers prefer walking passages; others prefer caves that offer opportunities to do some rappelling, climbing or diving (SCUBA).

The Pacific Northwest has a variety of caves, including limestone, marble, lava tubes and clay.

The grotto usually meets on the second Friday of each month at 7:30 PM at Round Table Pizza, 19121 Willamette Dr., West Linn 97068. The public is welcome to attend or join the grotto. New members must be approved by Grotto members.
For more information about our Grotto and how it is run, please review our Constitution and our By-Laws. To join or renew your membership, print out a Renewal form and send it to the appropriate person. The Willamette Valley Grotto has an email discussion list. It is open to members of the WVG and other local area grottos.
