SML Alumni & Friends Weekend

We are currently planning our activities schedule for summer 2023. Please check back for details.

Snorkelers heading out!

Building off the momentum of SML's 50th Anniversary Celebration in 2016, and inspired by the stories and memories of so many Shoalers, this event is meant to bring together our community and celebrate how much SML means to all of us! Whether you are an SML alum from our very first class or from our most recent class, a long-time volunteer, a current or former faculty member, or one of our many friends and supporters in the community, we welcome you to SML's Alumni & Friends Weekend!

Join us for a relaxing weekend connecting with old friends, meeting new ones, and exploring Appledore Island. Families are welcome (with the exception of minors in 2021)! Introduce your loved ones to the magic of Appledore, and show them the island and laboratories that have generated so many nostalgic memories.

Trek through the intertidal, tour Celia Thaxter's Garden, learn about SML's ongoing sustainability projects and upgrades, and more! If you prefer to spend your days chatting on the porch in the splendid late-summer sun, you can! This weekend is for you!
