This place is great! Ive been going there since I was a little kid & it hasnt changed at all since back then. 35 years or so & its still exactly the same. Now I take my kids there & they love it too!

Loved it! This is a small but beautiful park in Concord. Its very well maintained and a great place to enjoy while learning about the worlds flora.

So beautiful! Never seems crowded. No need to stay on any trail & it has creek! No restroom facility though so.... minus 1 star

Great place to have a walkabout and see all plants from multiple countries

It was wonderful!! So much fun for me visiting my son and grandchildren. The children love it so much.

Great place for a walk. I nice little nature retreat right in the middle of Concord.

Nice area to walk around and take in the unique nature.

If you love to see variety of trees, nice place to walk.

Markham is a beautiful park and is great for taking walks and other family activities. I actually did my Eagle Scout project here, so I hold this place in a special place in my heart and memory. The staff that work there are friendly and can answer most questions about the plant life there. Be sure to bring a hat and water with you if you visit during the warmer months, as it does get hot. All in all, this is a great park. Take a walk around and see for yourself.

Wonderful Nature center and setting. Great park. Many tree species throughout. The kids summer program is awesome and coincides with Cowell Park which has a Community pool less than half mile away.

Grew-up around this neighborhood love working this area.

A natural oasis very close to downtown Concord, the Markham arboretum becomes lush during the rainy season, which also replenishes the Galindo creek running through it. In the summer, watch our for snakes. Volunteers operating the nursery on site offer plants for sale on certain Saturdays.Behaved dogs on leash are welcome there and the lawns are great for children to play and enjoy a picnic on.This arboretum has the cozy feel of a real community garden.

I love this place. I love its story. It was the Markham family home that they donated to the city of Concord. Part of it has been developed as your basic city park. Part of it is Contra Costa Countys only arboretum. Part of it is Galindo Creek bed, part of it is community gardens. It has a nursery run by volunteers.

This is a great little park hidden away in the middle of Concord. The city and Im guessing volunteers seem to take great care if the wide variety of plants and flowers here, and theres a nice big grassy area that my daughter to run around in. Its close to our house so we try to walk over there several times a week, Ive noticed a lot less stoners in the parking lot which is great!

Great place for peace and tranquillity right in the middle of town

Loved taking my grandkids there, just needs a few tables and more benches

3/28/15Really pretty park, but rather small. Its a nice change of scenery if you want a place to relax and stroll among pretty plants or sit on the lawn. There are lots of shrubs, trees, and pretty flowers.We did see a lot of litter by the creek, and some kids who looked like wed caught them in the middle of something wrong when we glanced their direction. But weve had no problems here.

Well maintained and beautiful park with a nice walking path.

Beautiful relaxing areas to walk around.

Some litter but a beautiful place

What a beautiful gem, a wonderful and peaceful garden to enjoy natures variety from around the world.

I love this nature park, trees+plants from around the world. Also have plant sales

Whats not to like with 16 acres to view plants and enjoy the views

Love this place for unique plants. I look forward to the monthly Saturday sales from April to November.

A sliver of sereen woodlands and botanical gardens together nestling a manicured park.A respite from the surrounding suburban bustle.

Great Place To Walk Around With The Family Or Dog.

Relaxing. Great place for a walk with the family or picnic.

Went for the plant sale. Knowledgable staff, volunteers, and vendors plus such good prices make this my go to place to purchase plants.

Little slice of peace, beauty, and harmony in our little big utopia of Concord.

Local gem, not known to many. Great garden and trial access.

Garden oasis featuring international plants in the heart of the city. You may have lived in Concord for years and didnt know its there
