About

Indoor water park featuring a lazy river, two-story slides and a hot tub.

The pools and water attractions at Jolly Mon Indoor Water Park are heated and maintained at a comfortable temperature for guests' enjoyment throughout the year.

What are people saying (AI review summary)? This indoor water park receives mixed reviews, largely depending on the age of visitors and expectations. It is frequently described as ideal for younger children (8 and under) due to its shallow pools, kid-friendly slides, lazy river, and activity zone. However, many find it too small and not engaging enough for pre-teens or teenagers. Common complaints include an additional, often perceived as pricey, entry fee for resort guests, a shortage of tubes leading to long waits, and inconveniently located downstairs bathrooms. Some reviews also noted signs of wear like rust, a strong chlorine smell, and an unhelpful front desk employee. Despite these criticisms, families with young children often report a fun and positive experience suitable for family bonding, with amenities like a large hot tub, food, and beverage options being appreciated.

It was okay, one time experience. Made the best of it as we were already there and the kiddo was excited. Rusty and needs paint everywhere. Lots of chlorine, nose was burnt. The front desk employee, rude. Barely spoke. No thank you or have fun. It was fun for a one time but will not be going back unless I hear of an extreme overhaul.

This indoor water park is not that large and is more geared towards 8 and under. There are two bigger slides but that only keeps a 12 yo entertained for so long. Most resorts include the cost in the room but they charge $20 plus tax for people staying at the resort. Four of us was $84 and some change. A little pricey for what you get. There are no lifeguards and only two 2-person tubes. So you wait for a two person tube for some time. The toilets are down under the waterpark and I didn’t see many people go down and come back. So I am pretty sure they were all using the pools. One lazy river, one hot tub, one basketball pool, two higher slides, one kids area with 2 kids slides. Not very big. We decided not to go back another day and the kids were not disappointed in that.

Had a blast on the slides they were so much fun. The lazy River was a great time to relax and the hot tub close the day and made me feel like climbing in the bed and passing out! Overall a great opportunity for the family to bond and we had a great time.

Not what we expected. The lazy river is small and not enough tubes. Had to wait awhile to get one. The water slides were really dark inside. Kids didn't like that. Had to go downstairs for the bathrooms. It's not for preteens or teenagers. More for 8 yr olds and under.

It is Perfect for the younger kids! No pool deeper than 4ft, lazy river, 4 slides, large hot tub, food, adult beverages and kid ones too. Large activity zone, free tubes, lots of seating and a Ton of lockers (bring a few quarters) showers, and changing space. My girls loved it. Thank You to Jolly Mon!
