We used Tilly Jane as our base for hiking Cooper Spur (trail 600A to 600B) and it worked perfectly! The road getting here is not so great (you're driving up a mountain) but passable if you go slow. It's quite far up the mountain, so make sure you have everything you need. There isn't anything fancy about the campground, but it makes an adequate base for an early morning start.

Tilly Jane is also not far off the Timberline trail loop around the mountain, and the majority of people visiting the camping area were day hikers. The weather was very hot in the day, but got quite chilly at night.

In addition to the campground, the Tilly Jane A Frame is available as a rental- it was having some work done to it in August 18, so should be in good shape for the summer 19 and beyond camping seasons. There is also a small amphitheater in the campground.

The area around Tilly Jane is quite beautiful and different from a lot of the nearby forests. The drive up goes through an old burnt out forest, where you can see plants and trees coming back as well as dead trees that are still standing. It's an almost surreal landscape, and has great views of Hood, and great views to the north. The campground is small and the spots are not particularly secluded. We found a spot but saw several people look around for a while before giving up and going to Cloud Cap Saddle (which has the same issues). Get there early and you can find better spots, but don't expect much if you show up in the mid afternoon. There is wonderful hiking in the area, so the parking lots fill up with hikers during the day but it clears out quickly as it gets late.
