Jordanelle State Park offers two distinct recreation experiences near Heber City

At Jordanelle State Park, Hailstone is the premier development, with year-round day-use fees and the most services, while Rock Cliff offers a quieter entry at the east end. The choice matters because Jordanelle Reservoir, fed by the Provo River and held back by Jordanelle Dam, is built around access points that serve different kinds of trips.

What Jordanelle is, and why that matters

Jordanelle State Park sits near Heber City in Summit County, on the Wasatch Back, where the reservoir and the surrounding landscape are shaped as much by water management as by recreation. Jordanelle Dam was completed in 1993, making it a relatively recent major project in the area, and the reservoir supplies drinking water for users downstream from the dam.

The park does not feel like a single beach or a single boat ramp. It is a managed reservoir with multiple uses layered together: recreation, storage, and water delivery. For visitors, that means the best trip depends less on “going to Jordanelle” and more on deciding which side of Jordanelle serves the day you want.

Hailstone: the most developed entry point

Hailstone is the side most people should think of first when they want the broadest, easiest introduction to the park. Day-use fees are required there year-round. Modern restrooms, showers, playgrounds, and laundry rooms make Hailstone the most service-oriented stop in the park.

Visitors can picnic, camp, boat, and hike at Jordanelle, but Hailstone is where those activities are supported by the most built-out facilities. If you want the least complicated place to start, or you need conveniences that make a full day easier, Hailstone is the logical choice.

• Best fit for a first-time visit
• Strongest option for all-day outings
• Most useful when you want amenities close at hand
• The main place to start when you need the park’s most developed side

Because Hailstone is the main entrance and the busy end of the reservoir, it is also the side most likely to absorb the heavier flow of weekend traffic.

Rock Cliff: quieter water, trail access, and a different pace

Rock Cliff serves a different kind of trip. It is the quieter side of the lake, with its own campground and nature center.

The Rock Cliff Nature Center was remodeled and celebrated with a ceremony on November 2, 2021; Utah State Parks posted about it on November 3, 2021.

Rock Cliff is the better fit when the goal is a calmer shoreline experience, more breathing room, or easier connection to the park’s trail system. The Jordanelle Perimeter Trail runs from Hailstone on the west to the Nature Center at the east end.

How to choose between the two sides

Jordanelle has four main access points, each with different facilities and experiences. For most day-trippers, the useful split is still the one between Hailstone and Rock Cliff.

Use Hailstone when you want:

• the most developed access point
• year-round day-use service
• restrooms, showers, playgrounds, and laundry rooms
• the easiest base for boating, picnicking, or a full-day visit

Use Rock Cliff when you want:

• a quieter side of the reservoir
• its own campground and nature center
• a lower-key shoreline experience
• trail access that connects into the wider park system

A family looking for a packed day of water and amenities can use Hailstone, while someone chasing a calmer paddle or a walk near the Nature Center can head east instead.

What to check before you leave

Jordanelle’s conditions can change with heat, water levels, and wildfire risk. The Utah Department of Natural Resources posted in April 2022 about drought impacts on reservoir storage, and Utah State Parks has posted fire-restriction notices for the park during dry periods.
