A 5.4 mile loop trail through the woods of Sister Grove Park. Sister Grove Trail is a 5.4 mile loop trail through the woods of Sister Grove Park. It runs in an forest-clearing-forest-clearing fashion with heavy winding through the terrain to increase its length. The trail starts off innocently enough with a pretty meander near a small pond - and is quite well maintained toward its head - but as the end of the first mile approaches the undergrowth begins to start encroaching. For the majority of the trail the abundant poison ivy (I mean, it IS Texas) is too close for comfort. There are also a great many insects including quite a few territorial wasps that will aggressively buzz your face. Tall hikers beware! Whoever maintains this trail is SHORT! You will be crouching most of the way! There is wildlife on this trail. The VERY welcome meadow portions feature beautiful butterflies, dragon and damselflies, rodents, rabbits, and birds. The flora here is also quite beautiful - grasses and wildflowers depending on the season. The forests are DENSE, but there is animal life here too. BEAUTIFUL black/yellow garden spiders spin magnificent webs (albeit ACROSS the trail). If you're quiet and avoid crunching fallen plant debris you might glimpse a coyote or possum, both of which inhabit this area. All in all, the lack of trail maintenance puts a big damper on what could be an awesome hike.
