Pike pole has mostly small spaces.  Large enough for a tent or a single car.  Great for one or two people.  There are a couple places that could accommodate a few more.  Most seemed to have fire pits.  One or two had picnic tables.  They are very run down.  There is one toilet (unmaintained) at the trail head nearby.  If coming from the Encampment side you must find a route that takes you around the A BAR A ranch.  Two routes bring you through the property--it is gated and locked at the 512Y access.  Only FR 512 will get you there.  Be cautious of the switch backs going down into the canyon. Bighorn sheep wander the hillside and pop up on the road, on coming traffic (rare) are difficult to negotiate, there is no guardrail so presume the shoulder is "soft".  Dispersed camping in the area outside of the campground has much more space for larger groups and campers.
