Three County parks will close for the month of August as temperatures peak, an annual safety measure aimed at protecting residents during what is often the hottest time of the year.
El Capitan Preserve near Lakeside, Hellhole Canyon Preserve in Valley Center and Mt. Gower Preserve in Ramona will be closed through August.
Agua Caliente Regional Park and Vallecito County Park, which are in or near the Anza-Borrego Desert, remain closed for the summer after shutting down Memorial Day weekend. They will reopen Labor Day weekend.
Beyond heat-related safety, the seasonal closures allow Parks and Recreation to complete maintenance projects such as trail restoration.
Parks officials urge anyone hiking this summer to take extra precautions as dangerous health conditions persist.
Hot Weather Hiking Safety Tips
Choose trails suited to your fitness level and opt for safer routes if temperatures are high.
Stay hydrated before, during and after your hike.
Check the weather and understand the terrain.
Tell someone where you are going and when you expect to return. Don’t rely solely on your cell phone.
Hike with others; never go alone.
Bring food, water, extra sunscreen, a flashlight, first-aid kit, multipurpose tool and a whistle.
Carry at least one liter for every two to three miles, and even more water for longer or strenuous hikes.
Choose non-perishable items to eat like dried fruit, energy bars, trail mix, peanut butter, canned tuna, whole grain crackers or jerky.
Wear a hat, sunglasses and sunscreen.
Dress in layers of breathable, light-colored, loose-fitting clothing.
Wear sturdy boots that protect against hot ground and provide grip.
Follow posted safety rules and bring a printed trail map.
Heat Safety for Pets
Experts recommend leaving dogs at home when you go hiking in the heat. Pets overheat easily, and hot pavement can burn paws. If you bring your dog, carry plenty of water and avoid hot surfaces.
Never leave a dog in the car on an 85-degree or higher day. Interior temperatures can reach 102 degrees in 10 minutes and up to 120 degrees even with the windows down an inch or two.
With extreme heat expected in the coming days, the County shared some additional tips on how to stay safe in the heat.
