Part of Holiday World Theme Park — home of the $22 million Thunderbird roller coaster – Splashin’ Safari Water Park features two of the largest high tech water coasters in the world, the Mammoth and the Wildebeest. (They are also ranked the best in the country.) For those who might be a little too tiny or timid for these bad boys, there are also calmer adventures to be had including Bahari Wave Pool, Hyena Falls and Monsoon Lagoon. Tickets are $45 (adults) and $35 (children) but are offered at discounted rates online or at 3 p.m. at the gate.
