The whole area is dispersed camping as soon as you turn off of County Road 73C onto FR235. The ponds up the road from the main lake are full from lots of recent rain but all the campsites are still available. Most camp sites filled up for the weekend but we got there about 6pm on Friday evening and found a good site overlooking the big unnamed pond 1/2 mile up from Lost Lake. 

• 2023 June 24, 25 there was no snow at all.
• There were a few travel trailers parked in sites and all the roads are passable by 2WD. I counted at least 30 sites here and you can have several vehicles and set up multiple tents at many of them.
• Some spots are clearly marked with signs for dispersed camping. Most are not marked, but there are clear parking spots and fire rings at most of the sites. 
• A few sites that look accessible from Google maps satellite view have been blocked off to allow nature to regrow. Backpackers can still walk in to the sites where the road is blocked off to cars - the signs say foot traffic welcome.
• As you get closer to Lost Lake itself the spots are smaller and less flat so you might have better luck parking up the road from the lake if you have a large trailer or tent.
