This is the best campsite I have ever been to. Period. Part of me hates myself for sharing this with all you non-members... but I can't keep it all to myself.
Go ahead and skip the railed-in, tourist-filled section of the South Rim. Give yourself the chance to really experience the Grand Canyon - offroad through the backcountry.
Easy washboard and occasional tilty bits. Some easy rocky sections and some ruts from local traffic. Expect difficulty to increase significantly (mud) after precip over about 1/2". We did this two days after 1/4" of rain and enjoyed ourselves without the risk of getting stuck. I hear that it gets really gnarly in the wet.
Take 180/64 from Flagstaff north through Tusayan. I like taking 180 because it's a more scenic drive. It merges with 64 a few miles south of Tusayan in Valle. If you need fuel, get it in Valle. Your run is about 120 miles from Valle to the point round trip. Plenty of range and you save 30 cents a gallon or more.
0.5 miles south of the park entrance, about 9 miles north of Tusayan, turn left onto FR 328. Time for the dirt. It's well-maintained washboard for about 20 miles. Take your time, enjoy the scenery.
After 20 or so miles, you will stop at the closed gate. That's the entrance to the Havasupai reservation. When they have an attendant on duty, they will relieve you of $25 per vehicle per entrance (no going out for supplies and coming back in). Sometimes they have someone there. Sometimes they don't. Bring exact change just in case. It's worth it.
You have an additional 16 miles to go. Poorly maintained reservation roads, rocky sections and ruts will make your drive more interesting on this stretch. You are following signs to South Bass Trail, which is an 8 mile hike each way from the rim to the river. We'll get to that in a minute. Stock everything is fine. You probably won't even need 4 wheel drive, but you don't want to bring your prius out here.
There is only one real turn, and it has a sign. Ask your GPS to point you to the coordinates and you'll be fine.
Havasupai Point Overlook, Campground, and South Bass Trailhead
The point is a primitive campground. No water, no facilities, NO FIRES ALLOWED, but you are camping directly on the rim. You can stay here as long as you have provisions. The tribe doesn't seem to have a limit. Take a week and enjoy it. This is one of the least-visited places on the south rim. It is highly unlikely there will be anyone else there. When I came through, we were the only people the tribe ranger saw all weekend.
The campground is also the trailhead for the South Bass Trail. It's a beautiful 8 miles from the overlook down to the river. You can hike this trail during the day without a permit, but good luck getting all the way down and back up in one day. If you want to overnight, you can camp on the Colorado river, on a gorgeous beach, in the bottom of the canyon. BUT, you need a backcountry permit from the Grand Canyon National Park. Apply at least 3 weeks ahead of time for this permit.
That's it! More overlook camp/trail reviews coming soon.
