If you’re looking for a great outdoor activity to do while in Berkeley, then hiking is definitely the way to go. Here are three of the best hiking trails in the city.

1. Tilden Nature Area

Address: 600 Canon Drive, Berkeley, California 94708, United States

Just north of Tilden Regional Park lies the 740-acre preserve known as Tilden Nature Area. The preserve has more than 10 miles of hiking paths and is home to a mix of native and alien plant species, such as oak/bay woodlands, grasslands, eucalyptus forests, and streams.

At Tilden Nature Area one can also find the renowned Environmental Education Center (EEC), the headquarters for the area’s interpretive programs, and the historic Little Farm. 

The EES is the perfect place to learn about Wildcat Creek and all of the park’s activities. The exhibits are open from 10 a.m. to 4:30 p.m., Tuesday through Sunday,  can also buy nature-related books, materials, and even a self-guided trail booklet!

The Little Farm located nearby has heritage breeds of animals, including cows, sheep, goats, rabbits, chickens, and pigs. These beautiful creatures are well taken care of and the farm is open to visitors from 8:30 a.m. to 4 p.m.

Visitors are welcome to bring lettuce or celery to feed the animals. The park naturalists offer interpretive programs about the area’s natural and cultural history for schools, organized groups, and the public. To make school or group program reservations, please call the EEC or visit their website.

There are two ways that you can reach the Tilden Nature Area:

  • Take the University Avenue exit from Hwy 80 in Berkeley. Follow University towards the hills and turn left on Oxford St. Turn right on Rose St. Turn left on Spruce St., follow it up to a stop sign at the top of the hill, proceed through the intersection and turn immediately left down Canon Dr. At bottom of Canon, veer left onto Central Park Drive into the parking lot for Nature Area;
  • From Hwy 24, exit at Fish Ranch Road. Take Fish Ranch Road to Grizzly Peak Blvd and turn right. Continue on Grizzly Peak Blvd until you come to the intersection of Spruce Street, Wildcat Canyon Road, and Canon Drive. Turn right on Wildcat Canyon Rd, then immediately make a sharp left down Canon Drive. At the bottom of the hill, veer left onto Central Park Drive and follow into the parking lot for the Nature Area.

2. Stonewall-Panoramic Trail

Address: Berkeley, California, United States

The Stonewall-Panoramic Trail at Claremont Canyon Regional Preserve is a quick yet good hike that offers plenty of vistas and fitness for the money. Despite being close to the first viewpoint, where many hikers turn back, the trail is steep to begin with and remains so. On a clear day, you can see San Francisco and other Water Area bridges, including the Golden Gate, as the view of the bay drastically widens as you ascend. You can either turn around from the first viewpoint (which has a bench) or continue hiking farther uphill till you reach additional East Bay routes.

The trailhead for Stonewall Road is at the bend. The main path is obvious; it’s the one that continues upward even with all of the side trails meeting up with it as you go higher. As is usual for many trails in East Bay Regional Parks, dogs are allowed to be off-leash at Claremont Canyon (though please double-check the signs at the beginning of the trail for more details). Also, keep in mind that ticks are prevalent in this area.

With an elevation gain of 945 feet, don’t be discouraged by the four steep segments along this trail! You’ll have plenty of chances to rest and enjoy panoramic views in one of the terraced areas. As you hike through Claremont Canyon, take in all the diverse plant life including oak and bay laurel trees, eucalyptus trees, California sagebrush, and many other varieties of plants. This area is also populated with many different types of animals such as black-tailed deer, coyotes, gray foxes red-tailed hawks, and western garter snakes.

There are several places to stop and admire the view, or take a break if you need one. Look for Sather Tower on the UC Berkeley campus – you’ll get increasingly beautiful views of Oakland and San Francisco as you climb higher.

After approximately .7 miles of incline, you’ll finally be able to sit down on a bench and enjoy the wonderful view. If the bench is already occupied, don’t worry, there are plenty of other great spots to take in the scene. Once you’re satisfied, head back down or continue up towards the top of the ridge. The Stonewall Panoramic Trail is a free, 24-hour trail located at 99 Stonewall Rd in Berkeley, California.

3. Grizzly Peak Trail

Address: Berkeley, California, United States

Among all the hiking trails in Berkeley, Grizzly Peak has by far the best views—particularly during sunrise and sunset. Many locals and visitors love this trail because of the magnificent panoramas of Berkeley, San Francisco, and Oakland. Although it is a moderately difficult hike, it’s also very peaceful and calming at the top.

Grizzly Peak is the tallest point in the Berkeley Hills, located above Berkeley, California on the border of Alameda and Contra Costa counties. The peak is situated within Tilden Regional Park boundaries and directly overlooks the University of California campus.

The peak was named for the California grizzly bear, which used to live in the area until the late 1800s. The last sighting of a Grizzly Bear locally was by a man who supposedly got killed by one in Strawberry Canyon below Grizzly Peak back in the 1860s. On August 22, 1922, the last grizzly in California was killed east of Fresno in the Sierra foothills. This event occurred 150 years after the first recorded local killing of a grizzly by Europeans along Strawberry Creek west of UC Berkeley’s campus. The shooting by Spanish soldiers was documented by Father Juan Crespi.

Grizzly Peak became more convenient in 1932 when Grizzly Peak Boulevard was finished along the Berkeley Hills’ ridge line. The name was soon after given to the Euclid Avenue portion that had been constructed previously and runs parallel to the north. Berkeley’s original stretch largely remains unbuilt-upon while this section has always been a residential area.

Grizzly Peak Boulevard presently stretches from Kenyon Avenue in Kensington in the north, via Berkeley, and Oakland, to a junction with Skyline Boulevard above Oakland in the south.

Originally, where Grizzly Peak Boulevard and Claremont (formerly known as Telegraph Road) intersected with Fish Ranch Road was an important passageway through the Berkeley Hills. This was before the Caldecott Tunnel, which replaced today’s tunnel that goes through the hills, was constructed back in 1903. There used to be an inn and stage stop at this location called Summit House.

The best time to visit is during sunset, but no matter when you come, it will be worth your while. Grizzly Peak is popular among tourists and locals alike for its stunning views of the Golden Gate Bridge and Bay Area. It’s also not uncommon to see street luge enthusiasts in this area, especially sliding down Skyline Boulevard or Claremont Avenue into Berkeley.

2. How Close To The Property Line Can I Build An ADU In Berkeley, California?

Building an Accessory Dwelling Unit (ADU) in Berkeley, California is a great way to add additional living space and boost your home’s value. But how close to the property line can you build it?

Permits And Pass Inspections

Before starting any project in Berkeley, homeowners must first obtain permits and pass inspections. This includes planning out where exactly you will build your ADU so that it meets all local requirements.  You should also check with your neighbors to make sure they are comfortable with this. It is important to remember that, when building an ADU near the boundary line, it can affect both your and your neighbor’s view as well as have a potential impact on sun exposure.

Lot Size And Zoning Requirements

Lot Size

  1. The main house or existing structure must be situated on a regular-sized city lot zoned R‑2, R‑3A, R‑4, or RM-1; meaning the lot size must measure at least 3,500 square feet for single-family dwellings and 4,000 square feet for duplex dwellings.
  2. If your lot is larger than 6,000 square feet, you may be allowed to construct an ADU that measures up to 1,200 square feet.

Zoning Requirements

  1. How close the main house and ADU must be to the property line: The main house or existing structure must remain at least five feet from the rear and side lot lines, and the accessory unit must be placed no closer than three feet from those same lot lines.
  2. How many stories are permitted on an ADU: A single-story accessory dwelling can measure up to 25 percent of the total floor area of the primary dwelling (not including any basements, decks, or outdoor living spaces).

To sum up, how close you can build an ADU to the property line in Berkeley depends on many factors like lot size, zoning restrictions, and building codes that are applicable. It’s important to be aware of all these factors before beginning your project. Additionally, it may also be wise to consult a local expert to ensure that your proposed location for the ADU meets all applicable laws and regulations. This way, you can maximize the chances of having your application approved by the City and get started on your new ADU!

3. Is Building An ADU In Berkeley Worth The investment?

For many potential homeowners in the Bay Area, adding an accessory dwelling unit (ADU) to their Berkeley property can be a great investment. But before committing to such a large and important project, it’s important to ask: Is building an ADU in Berkeley worth the investment? The answer is yes. Building an ADU in Berkeley can be a wise financial decision for various reasons. 

ADU Adds Value To Your Home 

Not only does this create more space for you and your family, but if you decide to rent out your extra room or cottage, you could potentially generate additional income from your ADU as well.

ADU Can Also Increase The Overall Resale Value Of Your Property. 

Berkeley is becoming more and more popular for its distinctive charm, so it’s no surprise that adding extra living space to increase the size of your home can make it much more attractive to potential buyers down the line.

Local Governments Offer Subsidies

In short, building an ADU in Berkeley can be a great investment – both financially and aesthetically.
