Las Gallinas Valley Sanitary District   AG **** 2.5 miles Wet Weather Yes                   MORE INFO

This very accessible wetland restoration project offers great bird and wildlife watching. You can take a 4+ mile hike on the levee maintenance road (closed to cars) or, in just a few hundred feet, see lots of geese, white pelicans, egrets, ducks and other waterbirds. Otters are reported, but have so far eluded me. My last visit was on a warm June Saturday, when we saw only four people during a walk around the first pond. We speculated that potential visitors were scared off by the lack of shade here, but there was a pleasant breeze off the Bay, and had we had time to linger, a few of the benches are shaded by the few small trees planted by the trail.

Parking is right by the treatment plant, and the sulphur smell there might put you off, but it disappears when you cross a concrete bridge to the first pond. (Incline is steeper than 1/12 [1/8?] for about 10 feet at either end.) Picnic tables and drinking water for humans and dogs are near the information signboard, but no map was posted there when I visited. The trail is hard-packed well-graded gravel useable in wet weather, though it's a slightly bumpy ride and some soft spots make work for a manual chair user. It goes around the first, very appealing, pond (which has the best birdwatching and benches on its far side) and continues a good mile beyond it, past a second, less appealing pond and along the north edge of a broad marsh. After that, for another mile or so it's hard-packed dirt with irrigated fields on the left; then it turns to a rough footpath that might be possible but I haven't tried it yet. A bicyclist we met there said he had come from Hamilton Airforce Base. Last visit June 2006
