This is definitely one of the top if not our favorite park in TX. You've got to plan ahead and make reservations at peak times of the year as this is a super busy park. We really enjoy visiting g here in the fall and winter. The river is crystal clear with a tropical blueish green tint that is both cool and inviting. You have got to hike up the river and you will encounter many beautiful spots along the river banks. We found a fantastic swim hole located right at the base of a small waterfall. Be prepared for it to be potentially crowded atthe day use areas especially in the middle of the summer. The views and terrain in this region are breathtaking and like no where else in TX. It really feels like you are elsewhere. Do yourself a favor if tent camping and get a screened shelter site... if you want to be close to the day use area, stores,golf, etc.. be sure to stay in the old garner section. Overall very highly recommended. Be sure to hike up to old baldy and the crystal caves
