Location and Accessibility

Diamond Island South Campsite is situated on Diamond Island in Rainy Lake, which is near the city of International Falls, MN 56649. This entire area falls under the protection and jurisdiction of Voyageurs National Park. Rainy Lake is one of the four major interconnected lakes that define the park, and it is the closest to the city of International Falls.

The key factor determining accessibility is that this is strictly a **boat-in site**. There are no roads leading to the campsite. To reach Diamond Island South, visitors must travel across the water from a boat launch, such as the one at the Rainy Lake Visitor Center, which is approximately 6.2 miles away by water route. This necessitates having access to a private motorboat, a canoe, a kayak, or utilizing a local water taxi service. The water travel creates a natural barrier, preserving the pristine condition of the island and guaranteeing a high degree of seclusion for campers. Guests must be prepared for water travel and lake conditions. Due to the site's popularity, reservations are required and should be booked well in advance through the National Park Service reservation system.
