Very enjoyable trail I did with a friend. Quite a bit of ups and down but no long sustained hills. It gets a little traffic but not much as the crowded lower trail. We saw a lot of deer and waterfowl. I highly recommend this over the lake trail.
To do the entire trail you have to obtain a permit from EBMUD. Their office is by San Pablo reservoir and the permit is inexpensive and it's good for a couple of years. I've done this hike a few times and I've only seen a few people, all women, on the backside of the trail away from Bear Creek Rd. I rated it difficult only because of length. Not many people are prepared to do a hike this long. I've never had anyone else go along with me. There is all kinds of wildlife especially waterfowl and birds and the usual deer, coyotes, foxes and I've had a bobcat jump off a side hill about 20' in front of me as well. It would be best to take a friend along because of it remoteness and I've seen signs of mountain lions also. Take plenty of water, a permit and enjoy the hike. For safety there is a sign in board in the lower end of the lake when you go EBMUD property. This is a great fall through spring hike.
A pleasant paved and easy 2.7 miles trail. Most people can walk around this loop in about an hour. The path offers lovely scenery of the surrounding hills covered with virgin oak woods and an abundance of wildlife. A feast for the senses and the soul.
We hiked the upper rim of the Lafayette Reservoir. This track is longer than the Lafayette Reservoir Nature Trail (5 vs. 2.8 miles) and it has some very steep inclines, this is definitely not a beginner’s hike. The trail is a loop and has nice views of the Mt. Diablo and the surrounding areas. Hiking poles are highly recommended for the steep descent on some of the hills. Parking lot at the Lafayette Reservoir has daily entrance fee of $7.00.
We took the Rim Trail from the east side of the parking area to the Campolindo trail, descending down to the Lafayette Nature Trail. Campolindo Trail was very steep! The Nature Trail very busy! Aside from the good little workout, this trail offers grand views of Mt. Diablo to the east, surrounding residential neighborhoods, and the reservoir itself. I'm looking forward to completing the entire Rim Trail.
