Check out the sand dunes!
Enjoy a nice swim or grab some ice cream! On a quick jaunt to the campground you will find "Mount Baldy" A sand dune with a great view, especially at sunset! Please know that the beach is free to the public, but parking incurs a fee, consider parking downtown or in a nearby neighborhood to avoid parking fees.
A tried and true ice cream operation in downtown Pentwater. A cute mini golf set up as well, it's more fun than you think!
A favorite place for mini golf, go carting and arcades!
Charlie's has rental jet skis and other fun water sports! They can also help instruct on obtaining a fishing license, if that's more your speed.
Check out tubing rentals and have a lazy afternoon down a river... bring sunscreen.
Daily beach yoga from 9:30-10:30am at the state park! Yoga is $10/person, cash only.
