Honestly, all 265 acres of Hyrum State Park in Cache County, UT is worth a visit. If you're looking for adventure though, you'll pack a tarp and head to the dam.

There's plenty of fun to be had in a state park: fishing, boating, camping, picnicking, hiking, waterskiing,swimming...Until today though, we thought that there was nothing more fun than jumping off of cliffs into a reservoir. We stand corrected: Slip 'N Sliding off cliffs is way, way more awesome.

Make it a weekend; the park has 31 RV campsites, bathrooms with showers, a boat ramp, and endless hiking trails.
