The Arcadia Lake is a beautiful lake for camping, fishing, swimming, water boat riding and others. The lake has an entrance fee of ~8$ per day per car, and camping fee is around 20$. This lake is best place for fishing bass, crappie, bluegills, and catfish. You can do bbq here in the lake, there are lots of sites for grilling. There is also plenty of sitting place for picnic. You can easily spend and enjoy whole day here.
Me, my brother, and brother-in-law go camping every spring here. We also bring our kids so the wives can have a weekend without the little ones. We have always had a great time. There are several camp sites to choose from so you will definitely find one to your liking. The park is clean, as are the bathrooms, and there are trashcans throughout the park which are emptied regularly. It costs $24 to camp for the night but two tents and two cars are allowed at each campsite. One great thing about camping here is, you're not to far from the city in case of an emergency. I highly recommend Lake Arcadia for a quick getaway to nature with the family.
I have been visiting this lake for over 20 years. It remains one of my favorites. It has plenty of free places to visit if you look hard enough. Then don't forget the paid entrances that take you to camping, picnic benches, BBQs and beaches to swim with your kiddos. Watch out for the police. They have always heavily patrolled this lake. Which may make you feel safe! The beaches have a snack bar where they sell cold drinks and chips and candy. They have nice bathrooms that are maintained. They have plenty of RV hookups. The lake is always full of boats and water crafts. I see people fish all the time there. I have camped and swam here my whole life. Watch out for ticks! Don't let the red clay scare you. I recommend water shoes for this lake because it has a lot of rocks. I almost forgot all the kiddy playgrounds. It's totally worth buying a year pass for your car just so you can take your kids to a safe play to play! The woods all have worn walkways to hick.
