We stayed here twice 10 days apart in December since it was convenient incident to a longer trip. Our first site was in Oak Grove which I thought was much superior to Pecan Grove, site-wise. Pecan Grove 66 was by some nice warm clean bathrooms and showers but the site was up a steep slant and was just barely long enough for our 24 foot trailer. The park host came by and checked on us which was kind. Both sites had oak tree shade and picnic tables and were paved with asphalt.
Sites are electric and have water and 50/30 but no sewer. There’s a simple dump station.
There was a burn ban on but you could definitely smell wood fires both nights.
Small playground, easy hiking trails, and plenty of birds and nature walks. In the summer they have a pool which looked like it would be really nice. Not far from Abilene, we visited the zoo there.
