Gem mining, Moon rocks, hands-on art and science activities, exclusive tours, and free family experiences highlight Summer 2026
BETHEL, MAINE — Families looking for memorable Maine summer adventures will find plenty to explore with the Maine Mineral & Gem Museum (MMGM) this season, both at the museum and through community programs across Western Maine.
From gemstone hunting and meteorites to hands-on art and science activities, MMGM’s Summer 2026 offerings invite visitors of all ages to discover Maine’s geological heritage through fun, interactive experiences.
“This summer, we welcome families from across Maine and beyond for experiences that are both fun and meaningful,” said Kristy Griffin, Executive Director of the Maine Mineral & Gem Museum. “Whether you’re holding a piece of the Moon, uncovering gemstones at our sluice, creating artwork inspired by Maine’s natural beauty, or exploring our exhibits together, every visit is designed to spark curiosity and wonder.”
For families vacationing in the Bethel region, MMGM offers a perfect all-weather destination. Perfect for escaping a rainy afternoon, cooling off on a hot day, visitors will find experiences that inspire curiosity, discovery, and lifelong learning — no matter the weather.
Sluice Days Return June 20
One of MMGM’s most popular family activities, Sluice Days, returns June 20 through August 23.
Held every Saturday and Sunday from 11 a.m. to 3 p.m. Visitors can search for real gemstones and minerals at MMGM’s outdoor sluice. Participants sift through specially prepared mining tailings to uncover hidden treasures while learning about the minerals they discover.
To make the activity more accessible for families, MMGM has reduced prices for 2026. Sluice bags are available for $6 each or two for $10.
Bringing Art, Science, and Storytelling to Local Libraries
Beyond the museum’s walls, MMGM’s Education and Outreach team will bring a series of free family programs to libraries throughout Western Maine this summer.
Led by Education and Outreach Coordinator Deb Johnson, the programs combine children’s literature, geology, cultural history, art, and hands-on creativity. Library outreach programs are planned in Hiram, Norway, Bethel, and Buckfield. Schedules are available through participating libraries and MMGM’s event calendar (here).
“Some of the best learning happens when children can touch, create, ask questions, and explore alongside their families,” said Johnson. “We use stories, art, and hands-on activities to help children connect with the science in fun, memorable, and accessible ways.”
Planned themes include:
- Still Life & Maine Rocks: Inspired by “Vincent van Gogh,” by Susie Hodge. Children will learn how artists draw inspiration from the natural world before creating their own still-life artwork featuring Maine minerals.
- Clay Traditions: Following a reading of “Shaped by Her Hands,” by Anna Harber Freeman, participants will explore pottery traditions, examine real Maine clay, and create their own air-dry clay pots.
- Beach Landscapes: Inspired by “Little Houses,” by Kevin Henkes, and “A Day for Sandcastles,” by JonArno Lawson. Families will learn about Maine’s beaches and create watercolor landscapes using real sand and salt crystals.
- Sparkle Space Art: After reading “Margaret and the Moon,” by Dean Robbins, young explorers will learn about the solar system. Then, they’ll hold a real lunar meteorite and create a sparkling Moon-inspired art project using mica.
Explore Maine, Earth, and Beyond
From Maine’s mineral-rich pegmatites to rocks from the Moon and Mars, MMGM exhibits take visitors on a journey through Earth’s history and the solar system. Visitors can explore one of the world’s premier collections of Maine minerals and gemstones alongside an internationally significant meteorite collection featuring lunar and Martian specimens.
For a more personalized experience, MMGM’s new Stones to Stardust Exclusive Tours offer small-group guided access before the museum opens. Available on select Saturdays and Mondays, general admission for the remainder of the day is included.
Families on a budget can always enjoy the museum’s Discovery Gallery exhibits and activities for free! It offers hands-on opportunities to explore geology, minerals, meteorites, and Maine’s natural history through a variety of engaging, rotating exhibits.
