Parking & Directions

Jordanelle State Park has three separate areas with three separate entrances, so set your map to the one you want. Hailstone, the main area with the marina, beach and big campgrounds, is off US-40 at the Mayflower exit (exit 8), about 35 miles from Salt Lake City. Rock Cliff, on the east side near Kamas, is reached from SR-32. Ross Creek, the trailhead on the north arm, is off SR-248 between Park City and Kamas. Parking is covered by the day-use fee.

Hailstone (Main Area, Marina and Beach)

From Salt Lake City, take I-80 east to US-40, head south, and leave at the Mayflower exit, exit 8. Utah State Parks puts Hailstone about 35 miles from Salt Lake City. This is where you'll find the main boat ramp, the marina, the beach, the cabanas, and most of the campsites (Hailstone).

Rock Cliff (Provo River and Nature Center)

Take I-80 east to US-40, go south to SR-32, then east to Rock Cliff Road. Rock Cliff is about 45 miles from Salt Lake City, at the far east end of the reservoir where the Provo River flows in (Rock Cliff).

Ross Creek (Trailhead and North Arm)

Take I-80 east to US-40, go south to exit 4 (Kamas/Park City), then east on SR-248. The trailhead sits off SR-248 between Park City and Kamas, also about 45 miles from Salt Lake City. It has parking, two vault restrooms, trash cans, hitching posts and an entrance booth. Day-use fees apply here too (Ross Creek).

Parking Rules

• Park only in designated spaces, and keep all four tires on pavement. Rangers may cite or tow cars that don't.
• Vehicles stay on designated roads. Driving on the beaches or shoreline is not allowed.
• Riding in a boat while it's being towed on park roads is prohibited.
• The speed limit is 15 mph in every part of the park.
• Overnight boat parking is $30 a night, and that doesn't include the entrance fee.
• Sleeping in a vehicle in a parking lot is not allowed. Camping is only in designated sites (Camping).

Busy Days

The park can close to new vehicles when it reaches capacity. Utah State Parks notes that even an annual boat-slip hang tag doesn't guarantee parking during a capacity closure. Arrive early, bring one vehicle per group, and check the park's current conditions page before you leave.

Cost

Parking is part of the day-use fee: $20 per vehicle from May through October and $10 from November through April at Hailstone, Rock Cliff and Ross Creek (Hours & Fees).
