The time of year we visited the park was after a heavy rainstorm/flood three weeks before, thus we saw this remote scenic area covered in green and flowering wild shrubs not normally seen that time of year.
We haven't ever enjoyed having the thrill of two javalinas trotting along beside the car as they were crossing the road. Didn't have my camera ready for the many bird sightings. Butterflies everywhere. We hiked down a trail leading us right up to the Rio Grande just across from MX. There waiting for us was a Mexican wanting to sell us a 'walking stick' for . He would walk it accross the river to us! We declined.
Quick Tips:
Plan on at least three days to begin to really see this natural beauty. . .and follow the Rio Grande as it winds it way between the western border of TX and MX. You will experience views from high above the Rio Grande, and then there's times you can wade into the river and gaze above to the surrounding cliffs rising out of the water.
Best Way To Get Around:
To really enjoy this beautiful park, allow yourself plenty of time to feel free to park in a parking place and walk the many trails marked on the map you recieve at the entrance from the ranger. There all types of trails, from easy to difficult, take your pick. Wear comfortable shoes and always take water and some kind of insect spray, you may need some.
