I wish people would clean up their trash. Beautiful place for everyone including the dogs. I hope everyone realizes how lucky we are to have such a nice park and they stop littering with cans and bottles..

Dog friendly, clean, no there are no bathrooms or vendors but there is a Porta-Potty and you can always pack a cooler if you plan on spending the day. Great place to bring a float/tube and catch some sun. Only gave 4 stars because it's getting crowded... Shhhh stop telling everyone lol

Very nice area to spend my evening with my dog who is cooped up at home for 9 hours a day while I'm working. Just wish that some people would pick up their garbage instead of leaving it in the sand. There are trash bags available to throw your garbage away. And if you have a dog with you, be sure to bring bags to pick up their poo because nobody likes stepping in it.

There is a great dog friendly beach in Ahern State Park. Plenty of parking. The views are wonderful. Mostly locals, so it was very quiet compared to other lakes in the region.
