So I am going on a group trip to the San Marcos area within the next couple of months, and would really like to go hiking with a few people in the area one of the days that I'm there. I would love something with moderate to challenging trails, and preferably with some elevation (if possible) and pretty views (either a beautiful overlook, waterfalls, lots of flowers, etc.). What is nearby San Marcos that best fits this overall experience? I'm open to doing multiple trails as well, as long as it's all within the same state park.

Willing to drive about an hour (give or take) from San Marcos.
