The Park City dirt jumps are a complex of, well, sculpted dirt jumps set up progression-style from little bumps for kids on strider bikes, all the way up to some of the biggest jumps I've ever seen! Seriously, the lips on the big line are about 8 feet high, completely vertical, and absolutely enormous. If you want to go big, this is the place!
Best of all, this awesome park is on city property and is municipally funded. Score!
