Marin Municipal Water District Trails

The Marin Municipal Water District was built in 1912 to provide Marin County residents with drinking water. Today, the MMWD includes seven reservoirs, and 75% of the water comes from 21,600 acres of water around Mount Tamalpais and west Marin. In fact, in the surrounding area, there are more than 138 miles of trails for you to explore with your dog on a leash!

Dogs must remain at least 200 feet from the reservoirs, but they're allowed on the surrounding trails. The MMWD has adopted a "love 'em and leash 'em" policy and asks that aggressive dogs who may intimidate or disrupt local wildlife and visitors not use the facilities. Included in the 138 miles of hiking trails are 80 miles of unpaved roads where cycling is permitted, as well as several trails where equestrian use is allowed.

If you're up for a lengthy hike with your pooch, the two of you will want to check out Kent Trail along Alpine Lake. This 8.9-mile trail is rated as moderate, and it takes about five hours to complete. You and your dog will begin your journey at the Lake Bon Temp Dam in the MMWD, and the trail then takes you up and over the dam before you'll come to Alpine Lake. About an hour and a half into your hike, you'll come to a waterfall, and during the rainy season, you'll cross several small streams. Some areas of the hike will have you climbing staircases, so you and your doggo will definitely get a good workout! You'll go through dense forests and open areas around the lake, but wherever you are, you'll be surrounded by incredible views. 

For a shorter hike, you and your dog can opt for the Cataract Falls Trail. This 2.7-mile trail can be completed in under two hours, and it's rated as moderate. Whichever path you choose, be sure to pack plenty of drinking water for you and your pup, and always hike with a supply of doggie bags.
