This was my first time out on Bee Trace Trail and I had a great time. Both the hike into the campsite and out the next morning were pretty easy; the back half of the brown loop, specifically the stretch between the backpack camping site and the kayak camping sites, was sometimes frustratingly difficult to follow. I had to pull out my phone several times to get reoriented. That being said, that stretch isn't very long and the rest of the trail presented zero issues for navigation.
The campsite for backpacking is located at the very tip of the peninsula and it's a great spot. There is a camper-made fire ring here, but the regulations(and posted signs) state no fires, so I would be cautious with what you choose to do. The kayak sites are a little more developed, with picnic tables, trash hooks, and iron fire pits/grills, but I'm not sure how they feel about backpackers using those. On the day(s) I went through, I saw only two other people on the blue loop and nobody on the brown. However, I saw tons of boats out on the lake going by and they all had full view of the campsite(I think it would be pretty clear even once the trees are full); something to be aware of if you're looking for a super isolated camp. There is plenty of space to pitch a tent and many trees to choose from for hanging a hammock.
If you're looking to get your feet wet with backpacking(as I was), this is a great spot to do it. If you're a seasoned backpacker and are just looking for a quick out-and-back, I think you would be equally pleased.
The walk-in campgrounds (it's about a 50 foot walk from the parking lot to each site) at Long Branch are located off in their own little area at the shore of the lake that offers some pretty good isolation. Although we went at a time when the water was still shut off, there are bathrooms and water available via a very short walk from the walk-in sites April 1-Oct 31. The sites are each very spacious with flat areas and material already laid out for pitching a tent and plenty of trees for throwing up a hammock. Although firewood was stated to be available year round from the vending machine, it was locked up when we went through, but there is a convenience store right across the highway from the lake that sells wood bundles and anything else you might need.
We really enjoyed our time here and we'll definitely be coming back in the warmer months to enjoy some swimming and boating.
There are five tent camp spots located at Lazy Day and we camped on T4 at the very back of the campground. The on site facilities were excellent and clean, and these include a shop (with souvenirs as well as basic necessities and other assorted items), showers, and bathrooms. The T4 spot is pretty well isolated near the back and is right next to the trail that goes to one of the two fishing ponds on site. In addition to the trail leading to the back pond, there is another short trail that cuts through the woods on the south side of the camp. Despite the large size of the campground (about 65 RV spots) the noise level was fine and we went undisturbed while sleeping.
The largest camp area of Arrow Rock is definitely geared towards RVs, but there is a "basic loop" with twelve basic campsites for tent camping. There is a bathroom/shower house very close to the basic loop and the basic loop is well away from the RV area. Right up the road is Big Soldier Lake where you can fish as well. The camp host was helpful in providing firewood and was very attentive of the sites. The campsites are a bit crowded in with each other as there are 12 in the small basic loop, but a few campsites at the back end of the loop provide a lot of area to stretch and spread out into.
