Usually in parks the entry tickets are per car however here it’s per person. $5 ticket per adult but totally worth it for the blue bonnet blooms. Water body near by makes it even more spectacular. Apart from blue bonnets there are some white and yellow wildflowers as well. Nice place to chill out. There are some camping place as well. People bring their camp gears or just folding chairs and picnic blankets to enjoy nice view with blue bonnets fragrance in the air. Some hike trails. Quite a large area. You can drive car around and check it out. However the road are not concrete roads but just gravel and some rocks. So if you’ve car with low clearance- be careful going to steep roads. Restrooms available by the entrance. If you want to go there during blooming season - March last week and April first week are appropriate time for that.
