We spent the day hiking in Guadalupe National Park. The Visitors Center was a disappointment. The staff was not friendly or helpful. One of the bathrooms had a stopped up, feces full, overflowing toilet, and over 40 minutes after reporting it to the staff, the restroom was still open and the problem had not been addressed. The exhibit tags were worn and illegible in places and one of the fossil exhibits was incorrectly labeled. The hikes were amazing but the trails were not well-marked.
