I've stayed in both the cabins and the camping area. The cabins are my favorite because of the lake views, proximity to the bathhouse, and heat/AC units. Cabin #5 has the best unobstructed views of the lake. Cabins have WiFi. The campground is nice but only has a primitive toilet adjacent to the campsites. There are no electric or sewer hookups, but there are a couple of tent sites than can accommodate small campers. I camped in site #18 and it either isn't very level or I just did a poor job of setting up my tent because we were slanted all night. Great stargazing at both the cabins and the tent sites.
Check-in information is shared via email (key codes for the bathhouse and the cabin locks). The emails are very informative and the owners have been prompt to reply when I had questions. They even offer up the option to have firewood delivered to your site (either cabin or tent site) before you arrive.
This is my favorite place to stay in Crosby because it's so close to both the Rally Center Trailhead and Crosby. My favorite places in town are Red Raven (great coffee shop with good breakfast and lunch food options), Crosby Pub (wide variety of food - burgers, salads, appetizers), Rafferty's Pizza (pizza and beer plus a couple of arcade games in the back), and Iron Range Eatery (a little fancier than Crosby Pub (but not by much) and offers great food as well). All of these restaurants offer outdoor seating.
