Hyrum State Park

Day-use and annual passes are sold online at parkspass.utah.gov; exact current dollar amounts were not listed on the pages retrieved. Camping is by reservation in summer via ReserveAmerica (800-322-3770, 2+ days advance notice) or first-come, first-served with self-pay envelopes in the off-season.

Designated swim beach on a 450-acre reservoir with a protected no-motorized-boat zone marked by buoys near shore, which helps keep swimmers away from boat traffic. However, the park's own materials list no lifeguards, and reservoir entry can drop off from a sloped beach rather than a true shallow shelf, so young kids should be supervised closely.

No significant hike is required. The swimming area is close to parking and access.

A dedicated boat-trailer parking lot (35 spaces) exists and can fill during peak season; day-use requires payment via gate attendant or self-pay envelope box when unattended. Utah State Parks' general day-use schedule (found on a different park's page, not confirmed specifically for Hyrum) lists roughly $8 standard / $5 reduced / $20 family day-use rates, so treat the exact Hyrum figure as unconfirmed.

The park has a boat ramp and dock and is explicitly promoted for boating and waterskiing in addition to swimming, so full-size motorized craft are standard use here, not just paddle craft.

Summer, based on the park's description of 'an excellent beach' in summer and mid-summer water temperatures of 70-75°F.

Park hours are 6:00 a.m. to 10:00 p.m. daily. Watercraft that have been in Lake Powell or out of state within the previous 30 days must be inspected before launching, per invasive-species rules. Stage 2 fire restrictions (as of the page checked) prohibit open fires; only shielded gas/liquid-fueled camp stoves with a shut-off valve are allowed, with three feet of clearance.

Hyrum State Park is on Little Bear River, a natural reservoir verified in USGS hydrography data.
