We are deeply appreciative of the instrumental role Members have played in sustaining BMNSM through the successes of the Museum’s 27-year history, and in challenging times such as the onset of the pandemic in 2020, and now the aftermath of Hurricane Ian.

Although the Museum is closed until further notice to restore the facility, we hope you may still consider membership in support of BMNSM’s commitment to recover, remain on Sanibel, renew, and come back better than ever.

While membership cannot offer free admission to the Museum for the foreseeable future, it CAN still include valuable benefits such as free admission to over 1,100 other North American museums and attractions, and other benefits as described below.

Thank you for your support and consideration now during this extraordinary time. We look forward to welcoming you back!
