I can't say too much since I only went here once and didn't partake in any water or picnic activities.
I bought a Tonto daily park pass [$8] at my local Safeway, but I passed by the Walgreens everyone was talking about that you can buy it from because it's near the entrance of the park if you're coming from the west.
I arrived to Phon D Sutton Recreation area shortly before sunrise and it was super dark and I was the only one in that parking lot. But the view of the sun's red glow hitting the water was superb. There were about 2-3 picnic areas there and it was super buggy. Some garbage on the shoreline.
I drove out of that branch and off to Saguaro lake. I parked at the parking lot near where the boats slide into the water. If you keep on driving upwards, there's more parking but for boat trailers. Alsoo super buggy.
At Blue Point, there were 5-6 picnic areas and incredibly dirty. Someone had left their sack of garbage on one of the bbq racks. I jumped over the metal bar fencing in this area and walked to the water where I saw 10 vultures sitting on a dead tree - a little bit scary. But once I was at the water I spotted wild horses on the other side!
Goldfield Recreation site had a restroom but there wasn't much there. The shoreline was riddle with garbage cans and signs asking visitors to help clean up.
Overall, facilities-wise, not the best from what I observed. There were empty soda cans here and there. The picnic areas looked not the cleanest. It's super buggy. I'm pretty sure every kind of insect there rested its butt on me somewhere or bit me. However, the view is incredible. I was driving to Saguaro lake and I was in awe once I saw the water come into view. So, that's what makes it worth it.
