We camped here about 19 years ago & I swore I'd never go back. I hated the dirty bathrooms & showers. I hated the park in general. He talked me into going again & I was pleasantly surprised! Must be better management.  

 The playground looked fairly new. The bathrooms/showers had a plastic type lining on the walls. The rest looked like it needed a total rehaul. The bathrooms were "state park clean", which means the sinks & toilets were cleaned & not much else. I'm used to that!

    The sites were nicely kept, but some had a steep incline. I would call the park office directly if you're concerned. The F loop has the best sites. Some have a better view of the lake than others. The beach was closed for the season when we were there, but looked ok. They needed to get a Scout group or something to pick up small trash. 

  The fishing pier was closed because it's falling apart. There's a boat launch. 

The picnic areas looked uninteresting.

  The trails had pretty good with signage, but The Lake Vista Trail had downed trees every 50 feet. The vista wasn't all that great.

Although this is has 1300 acres this is a hikers park. Most of the acreage is accessible by trail. The Knobstone Trail has it's Southern most trailhead at this park. That's a 60 mile backpacking trail. The rest of the trails are much shorter, but it seems more rugged. The exceptions are Trail 1& 2- under 1 mile. The Lake Vista is 1.6 & very rugged due to the steep incline to the rock vista.

Fishing was poor according to my fishing guy, but it was in the 30s overnight a couple of nights. Warmer weather might be better.

 Sellersburg has restaurants & grocery stores. I saw a Walgreens.
