Unlike the other places you mentioned, it will not cool off at night in most of Texas. Not enough elevation & more humidity. Except for the Western areas.
In West Texas, Near Amarillo: Never been to the state park, but have read about it & would like to make it over there someday.
Palo Duro Canyon State Park as well as Caprock Canyons State Park, from what I have read, seem like very neat areas to see.
Southeast of Amarillo & Southwest of Quanah:
Caprock Canyons State Park & Trailway would make a neat place to check out. One I would like to see. Has a Bison herd I have read.
Ditto,
Copper Breaks State Park near Quanah sounds pretty cool (as in neat to see).
Likewise, there is
Monahans Sandhills State Park, just off the I-20 near Monahans. About 36 miles westbound from Odessa. Might be interesting.
Warmer still in the San Antonio Area & the
:C Texas Hill Country but a neat area.
Should be a nice time to visit the
:)Big Bend Area. We really enjoyed Balmorhea State Park & checking out
Fort Davis Nat'l Historic Site.
We did Big Bend on one our Spring Breaks some years ago. End of March, Start of April.
And the new
Boquillas Port of Entry might be some you would want to do. Not something we have done or would do.
The Texas Coastal Bend, especially Rockport/Corpus Christi areas & Lower Rio Grande Valley could cool off at night via the coastal breezes. What I have on the
RGV.
Ditto on RGVHere's a hodge podge of older posts (Some Repetition/Some New)
On Texas.
More on:
San Antonio & Corpus Christi.
Rio Grande Valley in South TexasAnother hodge podge of posts with some repeated info but with some new (I hope):
:h ClickySomethings I'd like to see, but haven't:
Texas Ranger Hall of Fame and Museum - Waco Amon Carter Museum of American Art - Fort Worth and
Kimbell Art Museum - Ft. Worth and
Other Fort Worth Art Museums:C Want to Escape the heat, New Mexico has some really scenic & Alpine cool areas.
Here's an old post of one of our more recent visits to a National Park in New Mexico as well as a State Park (even a BLM Campground).
Santa Fe & Bandelier Nat'l Mon't area of New Mexico -A Trip Report 2012.
Los Alamos is a very neat small city in itself. Free bus system with very neat buses. Very pretty setting up in the high country. Somewhat of a gated community as well. We only drove through & stopped at a SuperMarket. A nice town.
http://www.visit.losalamos.com/http://www.losalamosnm.us/transit/Pages/default.aspxOh, yes, in most of the western states, even in the hot southwest states, normally one does not to run the A/C at night to cool off. It usually cools down greatly at night out this way. Higher elevations & low humidity are factors. Therefore, one does need to have electrical hookups as one does back east.

Taos ::::::::
NM ByWaysA detour off I-25, after entering New Mexico, just off I-25,
Sugarite Canyon State Park by Raton is a neat area. And a short drive from Raton is the Capulin Volcano Nat'l Mon't.
A Neat Place. ------
But no CampingBetween Raton & Las Vegas, Not far S of Springer, just off I-25 is
Fort Union Nat'l Mon't.
At Las Vegas (older place than the one in NV)
Storrie Lake State Park, but we have used the Walmart there to do a few overnights. Lot of mountains behind Las Vegas (west) with National Forests campgrounds.
Off I-25 between Santa Fe & Las Vegas,
Villanueva State Park. It is off the 25 a bit. Somewhat off the beaten path. However, one can use NM 3 to cut down to the I-40 from Villanueva. We did that one visit.
Southern NM mountains & national forests can be very cool as well. Such as Cloudcroft & Ruidoso areas.
:C A really neat place is the Valley of Fires BLM Campground (near Carrizozo) is a first rate campground with electric & water hookups, good dump station and a fine shower house. Not Alpine area. Pics & description can be found:
Campground . . and . .
Cloudcroft, Lincoln/Capitan, Carrizozo/White Oaks.
More to the West, the Silver City & Gila Nat'l Forest Area can be neat places to see & explore.
The Gila Area (Pronounced Hee-La & means 'Spider') Plus a Scattering of Other NM Sites & Sights.
Unlike Texas & Colorado, NM state parks do not have an entrance fee on top of the camping fee as well.
NM State Park Fees are some of the lowest in the country. $10 camping without hookups, $4 more for electric.
Fees NM State ParksMost have free showers as well, a few do not have showers; such as the one above Santa Fe (Hyde Park).
