Haven't been here since before I moved to Florida. Not sure why it took me 8 years to get here since moving back.
This is a big, gorgeous park. There is a lot of beach here, plenty of places to fish from and put boats in, many shelters, grills, restrooms, camping areas, and a playground.
Even though we came late in the year (the Mead side of the lake seemed to have lost the majority of its leaves already), the views were still outstanding.
Didn't see any deer, but there were plenty of birds and small critters running around.
This park is well worth visiting.
There is currently a pretty bad blue-green algae bloom. If you bring a dog, make sure to keep them away from the water.
There are a few Pokestops spread throughout the park. We did not see any gyms. We had very weak signals here, though.
