I've been looking for someplace to log a lot of miles without doing a lot of backtracking. I found that SASP worked out pretty good. They advertise 50 miles of trail however I would say its closer to 30. They have quite a bit of side by side trail, one for horses and one for bikes. I wouldn't necessarily call it two trails since they are so close together and they use the same name. They have their trails broken down into so many segments. It does get a bit confusing with all of the segments, service roads and side by side trails. I think I was over half done hiking before I understood their trail marking system. Make sure and take a trail system map and utilize the larger maps at all of the waterholes to help keep yourself straight.
It was a beautiful day to hike. Weather was pleasant and I made very good time. There is not a lot of elevation change in the trails, what there is isn't real difficult. For the most part it wasn't very scenic. It was sad to see the dried up lake and all of the abandoned campground and picnic sites around the lake. There was very few people even in the SP. Once I started hiking I saw 2 people in 8 hours. There was evidence of trail maintenance and there is potable water in faucets every 3 or 4 miles so you don't have to lug a ton of water with you.
I started too late in the day for such a long hike. It got dark on me about 1.5 hours away from my vehicle. I had a headlamp with me but I had no spare batteries and the headlight started dimming so I made the decision to jump onto the park road and hike the last 2.5 miles back to my vehicle.
Overall I enjoyed the hike. I plan on going back and doing some more of the odds and ends trails later. If your looking for a good place to log some miles San Angelo is a good place to do it.
