Flower bloom - Bitterwater Rd., San Luis Obispo County


What? :

This blog post is from April 2023 when we have a rainy winter that enable the supper-bloom.


Bitterwater Rd., is one of the best spots to view glorious displays of wildflowers supper-bloom in Central California.


After my visit to Carrizo Plain National Monument I drove north back to San Francisco and decided to take this side road and enjoy the view of the colorful wildflowers blooming along the road.


Where? :

The exact location of this road is between highway 58 on the south and highway 41 on the north.


The highway 58 junction with this side road is located 6.1 mile west of the entrance/exit of Carrizo Plain National Monument.


Drive west 6.1 miles and turn right into the road.

From here the road keep going for 31.5 miles north all the way to it junction with highway 41.

Flower bloom - Highway 58, San Luis Obispo County

When? :

The best time to visit here is around spring, early/mid-April is probably the best month.

You should visit here only after rainy winter that enable the desert supper bloom, in “regular” year where there is not a lot of rain the flowers bloom is less impressive.


Due note 1: On all sides of the road, it is a private land with open cuttle grazing so respect the private ownership and do not trespass.


Due note 2: During supper-bloom years weekends there are many people that are stopping here so do expect congestion and maybe parking issues.


Due note 3: This is much smaller compared to Carrizo Plain National Monument but the flowers here are nice and colorful.


Due note 4: The road is condition is mostly good but there are some short ruff sections and also cuttle rails on the road so please drive slowly.



My thoughts:

I was on my way back home after my visit at Carrizo Plain National Monument and decided to take this sideroad and enjoy the flower blooming along my drive north.

I did not regret this 30 minute of additional driving time, this is remote area with only few cars and the hills cover with flowers were worth the extra time.



The visit:

The “visit” is simple, drive north along the road, enjoy the rolling hills open view and stop on the side of the road for flower viewing.


Some of the road sections pass through open cuttle grazing, please drive carefully and be carful of cows on the road.


Please do not cross any fences or respect signs indicating private property.
