We LOVE Split Rock State Park, and try to go at least one a year. This spring we backpacked in a bit to the first backpack site, BP1, just about a mile in from the parking lot. 

The cart in sites are definitely amazing, but the backpack ones are the best! This one is on an overlook with pretty much your own private lagoon right next to the site. Stats for this site: 

- mostly shaded at the site

- wood chips for the tent area

- bear box

-picnic table

- rustic latrine (bring own TP)

- fire pit.

There are trails down to the private beach area and to the public one to the north. You could totally access this via kayak or canoe.

Take the hike back to the main parking lot/camp entrance for use of nice showers and bathrooms. Also a little public bay with great views of an island and the lighthouse. Also has a great public use building with an outside sheltered fire pit and electricity. We hung out a bit there to charge phones and use the tables.

All sites are quite private, even more than most state parks. Various access points to Lake Superior throughout the campground, and the park is close to Two Harbors for supplies, etc.

One of my favorite parks, up on the cliff with amazing views and great trails that wind you through the woods to high bluffs and lookouts. Just awesome.
