We welcome donations. Because we operate entirely with volunteers on Bainbridge Island, virtually all of your donation will go directly to projects on Ometepe.

Donations are fully tax-deductible to the extent allowed by law because the Bainbridge Ometepe Sister Islands Association is recognized by the IRS as a 501(c)(3) non-profit charitable and educational organization. Our federal EIN is 91-1433369. Click here to see our tax returns.
