I used to volunteer here with my university club. The park is small but holds a variety of plants and most importantly birds. I haven't been there in almost a year but the only thing I would caution would be the entrance. It's a little hidden and it is a dirt road. Other than that if you come after a rain spell or summer make sure to bring bug spray! Thankfully the trees are tall and full enough to block most of the famous Brownsville sun but make sure to cover up anyways. Most people are volunteers and are happy to be there and thus very friendly. I know that they also recently renovated a historic house in the park and use it to hold events and meetings as well.
