We were here 2/20/21 to 2/26/21. Weather was great, mid 70's during the day, 40 to 50 at night. 

Horrible roads, takes forever to get anywhere! We loved the Isolation, saw very few people unless we went into the Ranger Station. Bathrooms and showers very clean, although never used showers. Bring tons of water! Can get more at Ranger station and also decent WIFI there. Free Ice is a huge bonus!

Had Texas Longhorns in camp. We have a Truck Camper on a Silverado 3500 and originally reserved Yedra 1. We were talked out of that site by a ranger and ended up in Tascate 1 instead which was just fine. We tried driving into Yedra later in our stay and turned around, so glad we didn't end up there.

Trails are plentiful and fantastic. The scenery fantastic. Be sure to bring everything you need food and alcohol wise!

Also, if you have the Texas state park pass, you don't pay the daily fees and you get discounted camping on at least one night plus discounts on gift store items. Was well worth it
