What a fun time! Cabana was worth it! Ild only say being a busy weekend, they need to check bathroom stalls often... I went into two stalls with no toilet paper. I told a staff person by the ramp area.. not sure if they considered checking. other than that. No complaints.

Beautiful clean beach and lake. Fun inflatables, water volleyball court, reserved covered picnic areas on the beach, and more. Not cheap but tons of fun on a summer day. Food trucks on site most days.

Horrible customer service from the start. We registered online with a 35" 5th wheel for 2 nights. On checking in, we wouldn't fit in the site so the girl at the desk put us in a different site saying she couldn't escort us to our site. This was our first time being there and her excuse was they were short staffed. The street signage was very small and hard to read. Site numbers were said to be on every pedestal but they were not visible from any drive. After only a few minutes of driving around, we were astonished by all the trash and junky trailers on site. Note that if your camper is more than 10 years old , they want to first see a picture of it so as to keep their place classy. Not the case here once you have paid and are here. We call back to the office for assistance finding our site and the girl said she would have to lock the office and was hesitant about doing so but she would come out to hep us find our place. We simply asked for a refund saying we were very disappointed with the situation so far. When she told us they don't give refunds, we asked for a manager to call us back. At this point we left to find another place which we did and were at in about 30 minutes. The manager called us back offering us drinks at the bar, a premium site, tickets for kids in the bounce house, and free water craft but I and the wife were only there for 2 nights. We were not going back to that dump. She said she would have to speak with the owners about a refund but never called us back. Five days later I called several times to speak with the manager again but no call back. She did however text us saying they will not issue a refund saying the girl in the office could not leave the desk because her coworker was using the restroom. Then why did she say she couldn't leave because they were short handed? Long story short, think long and hard before you visit this trashy place. Showers were dark and dingy and smelled. The beach looked more like gravel and not pleasing. Just walking around, I couldn't get away from the awful smell of people smoking and vaping and a strong smell of pot smokers everywhere. Not at all the place we would take our grand kids ever.

As a Dive professional, I haven’t seen a more well laid out and organized Dive Lake or Quarry! Very kind staff and nice that they answer the phone to field questions before you make the drive. Nice water visibility and lots of attractions on the map including the school bus, shipwrecks, and submarine! Highly recommend!

Our experience at Pearl Lake RV Park was far from what we expected, especially given the high price tag. When we arrived, our campsite had garbage on it, and instead of a scenic view, we were facing the maintenance building. The so-called “resort fee” is outrageous considering the lack of activities offered. While the lake water was fairly clear, the beach sand was dirty and low quality—not what you’d expect at a place calling itself a resort. The nicest part of the campground was the new basketball and pickleball courts, but that alone doesn’t justify the cost. There’s absolutely no security, and all staff were gone by 5 p.m. The lack of oversight was clear—our neighbor decided to fix his car right next to our fire pit after quiet hours, which was noisy and inconsiderate. Overall, this campground is overpriced and poorly maintained. We won’t be back. It felt more like a dump than a getaway.

It's a private place and $25 to go in ,big restrooms +showers. Good for kids , family. They close at 5 pm. Clean water fun slides. This time, there was a lot of polin in the water from the trees.

Pearl Lake is a very clean and peaceful place. There are lots of new positive upgrades and the staff is very accommodating and professional. We are looking forward to spending time out there again next year.

For a day trip, it’s great. Water is clean, even when it’s packed there is still plenty of space to stake your claim. Food trucks are convenient. Didn’t try the bar or restaurant. This is the best kept secret ever. We didn’t discover it until the end of the summer and managed to go twice. It will be our go-to next summer. Must say there is a HUGE difference in crowds on a weekday vs a weekend. I highly recommend a week day. The music is upbeat and fun. Inflatable climber for the kids.

Excellent. Pet friendly but not near beach. Bring alcoholic beverages but not in glass. Bring your own propane grill, chairs, umbrella or canopy.
