Light in Closed Canyon

Closed Canyon is a neat short hike (1.4 mile roundtrip) accessible off Hwy 170 (the majestic River Road) and is part of Big Bend Ranch State Park.  You enter a narrow opening between high rock walls up to 150 feet; this is a slot canyon.  Once you're inside, the temperature drops considerably making this a comfortable hike most every time of the year.
