Your first visit

Feeling unsure the first time is normal. Most groups are glad when someone new walks in.

First step: Join a first-Thursday meeting at 7:30 pm in Media or by video, then ask for a membership form..

You can just show up.

What to expect

A first visit is the monthly evening meeting, from 7:30 to 9:30 pm on the first Thursday, in person in Media or on video, and the site says you get a membership form there. Caving is physically demanding, and the site says beginners should go with experienced cavers and that members should be fit, healthy, sober and properly equipped. The site does not say whether guests can attend or what a first trip is like.

Tips for your first visit

  • If you plan to go caving, wear synthetic layers: caves stay around 55 degrees Fahrenheit with near 100 percent humidity.
  • Check the club's Equipment page before any cave trip, since the site links to one.
  • Go on trips with experienced cavers, as the site advises for beginners.

Newcomer welcome

Fine for newcomers, but you may need to speak up (3 out of 5). Why we say this: Monthly meetings are open and can be joined by video, and the site has a New Cavers page, but the site does not say whether guests can come along or what a first trip is like..
