I scouted this park while staying at Alsea falls campground just down the road.

Mcbee park is actually on the trail between Alsea falls and Green peak falls. One of the sites has the trail going right through it.

The sites were very large and some had some old shelters and tables. It is owned by the nearby Hull-oakes lumber company, but is open to the public. It looks like a local spot, but I'm sure it would be a good backup if Alsea falls is fully booked. They take reservations via phone, number found on entrance sign. (See photo)

Be prepared though, there are no services whatsoever, except maybe trash, so all backcountry rules apply. All in all a good location and right on the creek.
