Black Range Campsite is on the Six Foot Track, 10km from the Jenolan Caves. The campground is a flat, grassy area, surrounded by gum trees, with no defined tent sites. Bookings aren't required - it's a large campground with space for 30+ tents.
Acacia Flats is a walk-in campsite with no vehicle access, so it's perfect for active folks after a more remote backpacking experience. In addition to carrying in your gear, you'll need to be prepared for a good hike - there's several routes to Acacia Flats but all involve steep walks down into the valley from the cliffs above. It's well worth the effort though - you'll be rewarded with some of the most spectacular views in the Blue Mountains, plus you can have a dip in the Grose River.
