Renewing your membership with the
Rockcastle Karst Conservancy
We Can't Do It Without You

Keeping your membership up to date with the RKC is important. Your renewed membership will aid our land acquisitions by delivering a consistent source of revenue for RKC to utilize when opportunities arise.

Cavers are losing access everyday to the caves we love. Your renewals will create new karst preserves and open up access to caves.

Annual Membership renewals are payable on or before April 1st of every year.

Renewal Options

(NOTE: We have switched from Paypal to Zeffy to ensure all of your dues go to RKC.)
Note Changes with Using Zeffy:

Zeffy’s service is free to RKC.   PayPal, Square, and other services typically charge 3 to 5% to RKC. Zeffy supports itself through a tip (donation to themselves). Zeffy’s website adds this tip onto your RKC dues. That tip money goes to Zeffy – Not to RKC. You can change that amount. In the Summary section, click the arrow to the right of their suggested 17% amount and select "Other", then enter whatever tip you feel is fair.

This tip is your choice, so it's optional, but you must change it or their initial suggested amount (17%) will be added. It is not refundable.

If you don't want to remember to renew your Basic dues every year, please consider using the auto-renewal. You can cancel it anytime.

Here are the most common ways to join and support RKC:
Renew your Individual Regular Membership

Regular Memberships are $15 per fiscal year (April 1st to March 31st). This membership includes voting privileges for those 18 and older.

Sustaining Memberships

The Sustaining membership is a simple way to support Rockcastle Karst Conservancy. By having a small monthly amount ($5, $10, or more) charged to your credit card you keep the RKC moving forward in its efforts to be the leading non-profit organization in owning and protecting significant cave and karst resources.

Without this kind of steady and dependable support, it would be much more difficult to carry out our program of cave acquisition and protection

If you support our mission and would like to upgrade from a current individual membership, or are a current life member and are seeking a way to continue to support the RKC, consider starting a supporting membership
