Mount Madonna, also referred to as Cerro San Luis or San Luis Mountain, is one of the best hikes to do in San Luis Obispo (SLO), California. There are a few trails to choose from ranging from easy to moderate levels. As you make your way along the trail, you’ll get some amazing views of Bishop Peak (another tall mountain in the area and a recommended hiking spot) and San Luis Obispo County.
Whether you’re staying locally or visiting SLO for the weekend, this moderate hike can be done in an hour up to 2+ hours round trip. Plus, it’s free to visit!
We decided to do a double peak day as we already completed Bishop Peak earlier in the day. Compared to Bishop Peak’s out and back trail, we got lost trying to find the peak of Mount Madonna. We eventually made it to the top and enjoyed the views.
In this Mount Madonna hiking guide, we’re sharing how to hike to the top of Mount Madonna, how to get there, and other important hiking details.

There are two places to start the hiking trails – Charles A and Mary R Maino Open Space or Laguna Lake Park Open Space.
From Downtown to Charles A and Mary R Maino Open Space
To find the trailhead from Charles A and Mary R Maino Open Space, type “Marsh Street Parking Lot” in Google Maps.
From Downtown to the parking lot, take Marsh or Higuera Street and head towards 101-South. You’ll cross the freeway underpass and then see a sharp right opening before going on 101-South. This is where you’ll turn on Fernandez and park in the parking lot. (If you miss the opening, you can get off of the next exit and turn around.) Click here to see the driving directions.
*Note: You can walk here from the Downtown SLO area and there is a sidewalk that leads to the parking lot.
**There are a few bike racks to park your bike here.
From the parking lot, you can connect to the following trails:
- Lemon Grove Loop – It’s estimated to be 2.1 miles round trip with total climbing of 420 feet (128 meters) – Easiest route and great for beginners!
- M Trail – This trail is 2.6 miles round trip with total climbing of 640 feet (195 meters)
- M Trail to the Madonna Peak – This trail is over 5 miles round trip. (We took this trail after going partially on Lemon Grove Loop.)
From Downtown to Laguna Lake Park Open Space
There is a trail that connects to the peak of Mount Madonna with the starting location at the Laguna Lake Park Open Space. Input “Laguna Lake Park” or 504 Madonna Rd into Google Maps.
From Downtown to this parking lot, take Higuera Street and then continue on Madonna Road. The parking lot will be off of Madonna Road. Click to see the driving directions.
From here, you can take a trail that connects to the peak of Mount Madonna. Mountain bikers take this trail.
When To Hike Mount Madonna
Mount Madonna is open one hour before sunrise until one hour after sunset. If it’s still dark outside, don’t forget to bring headlamps for safety.
You can do the hike at any time of the day. It does get warm in the afternoon so you may consider hiking in the early morning or late afternoon. We did the hike in November and after 2:00pm so the weather was still warm for us. The average temperatures can reach 65-80℉ throughout the year.
The hiking trail is open and wide so it’s a great spot for social distancing.

Our Experience Hiking Mount Madonna
We were ambitious and decided to hike Madonna Mountain right after completing the Bishop Peak hike.
We started from the Charles A and Mary R Maino Open Space parking lot. The starting location is located within walking distance to the Downtown SLO area and can be visited after exploring the Downtown area.
We followed the path that lead to the Lemon Grove Loop. It was pretty flat with some gorgeous views of the city and the mountains. When we were about to go down the loop, we decided to change course and travel along the “M” Trail.
The M Trail is more challenging than the Lemon Grove Loop as the trail has some uphills. There are some walkways to make the hike easier. Most of the trail has shade so it’s a good area to cool off from the heat.
We eventually reached a landmark along the trail – a giant “M” in white paint. It’s visible when driving along 101 freeway. It’s thought to represent Madonna Mountain, but in reality, it’s for Mission College Prep High School. This high school isn’t far from the trail.
We continued the trail and noticed that the trail went back down to the parking lot.
How are we supposed to reach the peak? When heading down the M Trail, there is a fork in the road that leads to an unmarked path. If you continue along this path, then you’ll end reaching the hiking trail that goes to the peak.
At first, we were a bit lost since there wasn’t any signage. Yet, This part of the trail connects with the trail starting at Laguna Lake Park Open Space. We saw mountain bikers and a few hikers.
The hiking trail is much wider and goes uphill. It seems like the trail goes on forever since the trail is mostly gravel and not that exciting. Plus, there isn’t any shade here so a hat will go a long way.
After making our way around the mountain and seeing Bishop Peak, we eventually made it to the top of Madonna Mountain! WooHoo!
There is a platform to take a break and rest.
Or, climb up some boulders for undisturbed views of Cal Poly and the surrounding areas. The boulders are not as sketchy as the ones in Bishop Peak so it’s doable to climb up. There was only a handful of people at the peak.
Don’t forget to take photos from here. SLO is so pretty and green! There is a pole where you can step up and take a photo with. It’s similar to Mission Peak’s post in Fremont, California.
Going back down the path is the same way as coming up. Or you can continue your way back to Lemon Grove Loop to do more mileage.
Since we were tired from walking around the mountain, we just went down the M Trail to reach the parking lot and called it a day. We were pleased with hiking this trail and would love to come back to do this again.
Mount Madonna is a fun day hike to experience when visiting SLO. From the easier Lemon Grove Loop to the more challenging peak summit, this hike is a fantastic way to get some fresh air and spend time outdoors. Enjoy this exciting outdoor activity in SLO!
