Devils Tower is hard to miss as you approach it

The tower is 265 meters tall

The sides are made up of strange, mainly hexagonal pillars formed as the rock cooled

Quite a view

Once up and into the mountains, there was a relatively flat plateau

This part of the road is 9,430ft above sea level - still lots of snow around

There were lots of wild flowers

RVs and trucks were asked to pull over and study the sign before deciding whether to take the scenic but steeper descent, or the main highway. We chose the former - what could possibly go wrong?

Another sign at a mandatory stop just before the descent

We stopped for lunch about a third of the way down

Amazing views

This was around three-quarters of the way down, and shows how the road was cut out of the rocks

We first picked up the RV in Billings, Montana - and then covered 1,480 miles on our journey to Theodore Roosevelt National Park in North Dakota, down to Badlands National Park in South Dakota, and then across to the Bighorn Mountains in Wyoming via the Black Hills and Devil's Tower, before finally heading back up to Billings again. The red crosses show the RV parks that we stayed at. Click here for the full size version.
