I suggested in an earlier post that we could start at the Harry Wade Exit Route off Highway 127 North of Baker and South of Shoshone and enter the park from there. We could even camp out the first night on the Route or somewhere nearby.
Susie and I did a quick run out there last weekend. It had been quite a few years since we'd been out there so we thought what the heck - let's go camping and check out the area. We ended up driving the Harry Wade in both directions.

The first several miles or so has BLM land on the Southern (left) side of the road. The North side is within the park. One point seven (1.7) miles from Hwy 127 on the Harry Wade there is a trail on the left leading up to the Avawatz Mtns that would be a decent first-night's camp spot right off the Route. I spoke to a BLM ranger (Jeff) who stated that we'd be fine there with a small group (six or so). As you go up this trail further a few folks could find a spot or two but as the terrain begins to get steeper it would be more difficult to get a level spot. However, this area right near the Harry Wade Route could be an excellent first night's starting point and would be easy to spot for someone coming in, even after dark.
The only bummer is the lack of privacy for anyone needing to partake of a bush. There's hardly any. You can walk a half-mile away and still be right out in the open. Something to think about.
The Harry Wade is in very good shape. It's 30 miles long with some washboard (worst was the first couple of miles off highway 127), some soft sand, and areas where you could motor along quite nicely for miles at a time. I really don't think a two-wheel drive would have a problem since I never engaged the transfer case the whole time.
Here's a shot of the road past the half-way point.

When we exited the Harry Wade Route on the Badwater Road and headed into Furnace Creek to visit the visitor center we spotted three coyotes and two ravens begging food from tourists on the side of the road. Of course we didn't feed them (illegal) but we did take advantage of the photo-op.

During our two days out there we visited Saratoga Springs and walked around the Confidence Mill Site ruins, found a remote campsite up Ibex Road with a view of the Ibex Dunes and generally enjoyed ourselves. If you've never been out there, own a popup camper, and want to have a chance to see some stunning scenery then this might be the chance.
By the way, if the Harry Wade Exit Route first night's campsite is not acceptable there is always Afton Canyon Campground off I-15. This is an established campground that has restrooms and level spots. Can't guarantee enough spaces but it is a possibility for a first night. The distance from Afton Canyon to Baker, then North to the Harry Wade Route is a short, easy drive.
Anyone have any other suggestions?
