The Estivant Pines Nature Sanctuary is home to the oldest living trees in Michigan. It is owned and cared for by the MIchigan Nature Association.

The sancuary is about 2.5 miles south of Copper Harbor, accessible by road during the summer months. Follow the signs heading toward Lake Manganese. You may park off the road at the entrance. The trails are for feet only, no vehicles of any kind. Pets must be leashed. There's no camping allowed.

The 1.5-mile Cathedral Grove Trail and the 1.4-mile Memorial Grove Loop feature many pines that are more than 100 feet tall and 200 years old. Be on the lookout for the Pileated woodpecker or his square cornered holes. You may also see some of the "Memory Trees" which bear plaques loosely mounted on some of the gargantuan pines in honor of loved ones who loved this forest.

Enjoy a variety of tree species including maple, birch, cedar and of course the stars of the show - White pine. The spring and summer show off many rare fern species, precious orchids and other delicate woodland plants. Fall brings a bounty of mushrooms in many shapes and colors.

As is the case for all Copper Harbor hikes and walks, sturdy shoes are recommended. Trails are narrow and very hilly in spots and there are many roots to navigate.
