Big Flat has lots of shade and places for tent camping. Enough space for many vehicles to park. A nice stream running by it as well. Or you can hike to Caribou Lake where there's a beautiful camping area for tents.

From Big Flat, a few mile hike will take you to Caribou Lake. Big Flat itself has plenty of space for car and tent camping with a stream running next to it. There is plenty of shady spots available. Many hiking trails start here. On the trail from Big Flat to Carabou Lake

Big Flat is a sweet campground nestled in the Klamath Mountains. This camp offers a great place to mellow out beside Trinity River or a base before hiking out to Caribou Lakes.

Wonderful Campground worth the drive in- no low clearance vehicles. 12$ pay station and corals for horses. There are approximately 7 different trailheads from this road which extends deep into the wilderness, ideal for horses lots of water. Note this is a pack it out campground- So plan to camp after you hike as bears are also known to break into cars with trash here, I took some other backpackers trash out with me since there were leaving for 4 nights to the lake 9mile hike. LEAVE NO TRACE!
