Unlike the western regions of the United States, there are only two national parks in Texas – Big Bend at the Rio Grande and Guadalupe Mountains with Signal Peak, highest point in Texas. On our round trip we visited both of them. Our picture show is completed by a detour to New Mexico, where the dripstone caves of Carlsbad Caverns are another attractive destination. The amazing dunes of the White Sands National Park are also situated in New Mexico and should not be missed.
