"A 218,000-acre, water-focused national park in northern Minnesota best explored by boat; it encompasses roughly 30 lakes and 500 islands, and most campsites are accessible only via water so visitors are encouraged to reserve boat transfers and campsites in advance. The park does not require an entry pass, but planning ahead is important—options include self-captained boats, guided tours, or renting a houseboat from private providers (which requires permits and extra fees). Guided offerings from mid‑June through September range from short scenic trips to multihour historic excursions that visit lakes and rivers and explain the region’s trapping, logging, mining, and fishing heritage. Activities include canoeing, kayaking, swimming, fishing, and wildlife viewing, and the area is recognized as an International Dark Sky Park with good chances to see the northern lights, especially around September when conditions are warmer." - Lydia Mansel Lydia Mansel Lydia Mansel is a writer with more than eight years of experience editing and writing for both brands and online publications—with a particular focus on travel, fashion, and lifestyle.
