Viejas Peak is a prominent peak in the foothills of San Diego County located about 30 miles from downtown San Diego. The nearest city is Alpine. The peak is isolated from surrounding peaks so it lends itself to a wonderful 360 degree panoramic view.
The peak stands at 4,187 feet above sea level. The most popular trail to the top is a rather steep trail and climbs about 1000 feet elevation gain per mile. The round trip mileage is about 3.7 miles. The start of the trail is off Anderson Truck Trail located north of Alpine. The road leading to it is dirt and most cars can travel this with no problem. However, one must realize that the shoulder of the road has room for 6-8 cars but parking requires an Adventure Pass parking pass. Otherwise, you can park down on the paved the road before the gate about 1/4 mile and walk up the road.
As mentioned, this trail is fairly steep and there are a lot of loose rocks. This trail is not for those with weak ankles as coming down this grade increases the risk of a mis-step. This trail should not be attempted at midday during the summer time. There is no shade and the temperatures can climb above 100 degrees. I have hiked this trail several times and my favorite is early spring in the morning hiking in the fog or marine layer and popping out on top to see the sun shining on a sea of fluffy clouds.
The view is great during the entire trip. Nice views to the west open up to a 360 view when on top. To the east are great views of the taller mountains of Cuyamaca, Laguna and to the north Palomar. This is a great peak to bag and a great peak for training for longer treks such as Mt Whitney.
