Bernardo Waterfowl Tour is a 2.7 mile moderately trafficked loop trail located near La Joya, New Mexico. The trail is good for all skill levels and primarily used for hiking, birding, and off road driving.
off road driving
This is actually an area where most people drive through but there are two short trails off the road and I would recommend walking the loop instead of driving. It is flat and easy (Take a Camera) -- December and January provide the best bird viewing months. Dirt Road that is flat.
I am assuming this place is a wonderful place for birding during winter migration, as the signs in the park explain. The "trail" is a ~3 mile loop meant for driving(15mph) or hiking and is flat terrain with little shade. There are some small trails with viewing platforms for bird watching along the way, as well as plenty of places for picnicking and outdoor bathrooms, as well. I know I came in off season but saw some killdeer, roadrunner and wrens!
I really enjoy this area. It has good bird viewing without the crowds and you are able to be closer to the birds here, so you can get better pictures even with a nominal camera.
