This is one of our city swimming pools. It is just as cool to swim in as you can imagine looking at this picture. It's a 50 foot heated salt water pool. It's open for weekends in May and then June-August. The best time to go is a rainy day in May. You can find parking and it's not crowded.
The big issue with this pool is getting there. You have two choices. You can hike through those woods which is very hilly under that terrain and the trails wind back and forth and it's amazingly easy to get 100% lost. OR you can hike on the shore. See the pier sticking out up there on the right? You come in up just south of that pier (where the woodsy part starts) and then walk to the pool from there. It's pretty flat - a long, flat walk. BUT the rub is that to get to the flat part from the road or parking lot, you have to go down a steep hill and then the whole time you are swimming you are worried about your ability to get up that fucking hill after walking all that way. If you are me, that is.
So I haven't been in a couple of years but if we get some chilly rainy days when no one else thinks swimming, I might just give it another go.
