Flat and easy. Today was windy and cloudy, but also warm. it was a beautiful day for the hike. A lot of birds to see, snails and squirrels too. A nice variety of flowers and other marsh plants. Saw a couple varieties of sage and some blossom lilac that the squirrels and bees seemed to love.

Very nice trail for beginners. I took my 9 year old son who’s a novice and completed the trail in 45 minutes at a leisurely pace. Not too crowded with nice view and evening breeze

Pretty great trail with a lot of birds and ducks!!! Good views too :( downside is that it has no shade and could get some sunburn easily

A pleasant, easy loop -- though be prepared for lots of wind and sun. Not crowded even on Memorial Day. Some cool bird life. A good place to get moving -- some cool views though it can be monotonous for stretches. I enjoyed it. Seemed like it would be a great little running or cycling loop. (This entry may be a duplicate with the Don Edwards Wildlife Refuge listing by mistake.) The tiny loop by the pump house is also worth doing -- egrets and cormorants over there.

Wonderful sight of nature that's such heart opening! Beautiful weather today too! So close to the bridge and toll plaza and nice learning of marshland and February birds there as well.

Nice flat walking with limited shade. The visitor center is worth a stop.

It used to look like The previous photo posted. My son and I like to hike on the Mallard Sough Trail at the Don Edwards wildlife refuge located near Alviso . We have seen a layer of intense green algae like pea soup growing over the salt water pond very rapidly with a sulfuric smell. It has worried me to see snowy Egrets swimming around in it. Also black legged stilts and other rare birds. 683C59D7-0727-499D-AE54-0580625591A7 Photos on the left are from algae on the Mallard Slough trail at Don Edwards refuge. This was taken on the Lagoon next to the trail called Mallard Slough, not the salt pond on the other side of the trail that has algae . The first photo was taken April 27, 2015. The photo below was taken June 3rd. No birds !! And drained way down even though it was full of water a week ago. I have never seen it look so desolate . I'm concerned since I did see at least 2 dead birds in the path. I'm concerned that this is the last of these birds in our salt marshes. Very sad. Mary Hahn Sent from my iPhone In the past this place was beautiful but the beauty has been spoiled by the algae bloom. Possibly an industrial seepage from nearby facilities . I need to figure out how to post photos for this.

Surprised to find there are two entrances to the park. One in Fremont the other in Milpitas / Alviso area. Nice place for casual stroll. Small museum currently under construction for renovations. Can be a bit smelly due to salt marshes but there is usually a nice breeze.

For visitors. Stay at the Aloft hotel across the street and run or hike here. Beautiful place. Too bad the hotel doesn't still offer use of bikes.
