Top Things to Do in Henry W. Coe State Park

1. Mountain Biking

Mountain Biker

Henry W. Coe State Park is very popular with mountain bikers. Some even call it the mecca of this sport. With 200 miles of tracks for mountain bikes, it isn’t difficult to imagine why.

However, the park isn’t very beginner-friendly. There are practically no easy biking routes in the park. Most trails are described as moderate and difficult. 

Scorching summer heat is another issue for bikers. Walking at your own pace is one thing, but riding the bike up the mountain can break a man in these conditions. You’ve been warned! 

The good news is that Class 1 e-bikes are allowed in Henry W. Coe State Park. So if you want to give yourself a leg up, bring one of those and enjoy uphills too.

The Best Mountain Bike Trails in Henry W. Coe State Park:

1) Durch’s Trail

Dutch’s Trail is located in the southeastern corner of the park. It is best accessed from the Dowdy Ranch entrance. The track is a popular 3.5 miles downhill single track that is rated difficult.

2) Jim Donnelly Trail

Jim Donnelly Trail is a painful but popular uphill grind from the Hunting Hollow entrance to the ridge. You can take this 4.7-miles singletrack down to the car park as well.

3) JD East Connector Trail

JD East Connector Trail is a short off-shoot of Jim Donnelly Trail (see above) in the Hunting Hollow area. It’s only a mile long but has over ten switchbacks. Give it a go!

4) Spike Jones Trail

Spike Jones Trail is another single track in the Hunting Hollow area. If you climbed up the ridge using Jim Donnelly, this Trail is your best course of action. The downhill, 2.1 miles singletrack, is super popular with mountain bikers.

5) Cross Canyon Trail

Cross Canyon Trail is about halfway between Hunting Hollow and Coe Ranch areas, so it isn’t easily accessible. The Trail is down and up singletrack rated difficult, and it is 5 miles long. It will take you from Coit Road to Coit Spring Trail, where you can link to the Grapevine trail and continue the descent. 

Another option for mountain bikers is to go out there and explore the park. There are dozens of trails on offer; each has its own peculiarities and challenges. Enjoy the ride!

Henry W. Coe State Park may not be the mecca for mountain biking yet, but it is slowly getting there as more and more bikers discover the area. So come and enjoy the park while it is still uncrowded and cheap to visit.

2. Bikepacking

Bikepacking during the sunset

Bikepacking combines both backpacking and cycling. Load your bike with a tent and a sleeping bag, and you get yourself a home on the wheels. The rest is the details.  

Because of the size of the park – 87,000 acres – it is a perfect place for bikepacking. With dozens of trails and fire roads, you won’t have to take the same track twice.

You can probably spend a week riding here and still have unexplored sections.

If you live in the area, you can use the park to test your equipment and bike set up before more extensive trips. 

However, the terrain here is very hilly, so that bikepacking will suit more experienced riders. And once again, it’s hot here, including September, so plan your water supply.

3. Fishing


Fishing in Henry W. Coe State Park is allowed all year round, subject to state and federal regulations. The park has many ponds, creeks, and lakes for you to enjoy. 

You can catch bass, crappie, sunfish, and bluegill, as well as the rainbow trout that can be found in a few cool creeks.

The difficulty with fishing in the park is that you can’t access fishing spots by car. You will have to transport your gear on foot, and the terrain is famously rugged with strenuous uphills and heat. So if you are used to bringing a trunk-load of equipment, forget it, fishing in Coe Park is a different kettle of fish.

The best fishing locations in Henry W. Coe State Park are Bass Pond, Coit Lake, Mississippi Lake, Frog Lake, and Kelly Lake.  

For the complete list of locations and details about fishing in the park, see this page.

The park rangers here are very knowledgeable and friendly. They can recommend the best hiking trail for your circumstances and equip you with an excellent map.

5. Backpacking

Backpacking is a bigger brother of hiking. Basically, hiking with overnight camping is backpacking. And there is a lot of that here at Henry W. Coe State Park.

With most trails and loops longer than 15 miles and 87,000 acres to explore, you can escape for weeks at a time. Just let somebody know you’ve gone wild; otherwise, people will search for you with the helicopter.

If you are planning a backpacking trip in the summer, you must research your water supply points. There are many creeks, lakes, and ponds in the park, but many of them dry up in late summer, so have a backup. For more information on water resources, see this page.

There are plenty of campsites throughout the park; most have a picnic table and a place for a tent, and that’s it. Good luck!

6. Horseback Riding

Horseback riding at Henry W. Coe State Park is actively encouraged. There are multiple campgrounds for horse camping here.

Long before Diablo Range became Henry W. Coe State Park, this area was used to drive wild Californian horses down south. Hence, the equestrian ways are deep-rooted here. 

For more information on horseback riding and camping, see this page.

7. Geocaching

Geocaching at Henry Coe Park

9. Visit Tarantula Fest

Tarantula fest Henry Coe Park

Tarantula fest is held once a year, usually in late September, at Coe Ranch campground. This time of the year is tarantula’s mating season, so they are very active and easy to find.

Despite a widespread belief, tarantulas are not dangerous to humans. They are just big and hairy, which scares a lot of people. Tarantula Fest is your chance to hold and pat these furry creatures and conquer your fears.

10. Visit Pacheco Falls

Pacheco Falls is a series of waterfalls in the center of the park. The best time to visit the cascades is in spring, while there is still water flowing. You may be disappointed if you see the falls in late summer because instead of a spectacular torrent, you will find miserly drops. 

Pacheco Falls area is very remote, and you need at least two days to visit the cascades. Although the Dowdy Ranch entrance is the nearest, the hike is usually attempted from the Hunting Hollow entrance. From here, it is 25 miles return trip.

For more information about this route, see this page.

11. Climb Mount Sizer

As mentioned before, Mount Sizer is the most prominent peak in the park and its favorite destination. 

It is approached from the Coe Ranch entrance and is usually done as a 16-miles Mount Sizer Loop. 

Sixteen miles may not seem like a lot to experienced hikers, but the terrain is steep, and you are looking at 4,300 feet of elevation change. Hence, many people plan two days for this route.

Because a portion of the track follows the ridge, there is a lack of water sources along the way. Hence, bring lots with you.

Despite this, the loop is the top destination in the park. If you only have a weekend here, climbing Mount Sizer is your best option.

Jeff Hester published an excellent report of this route.

12. Stargazing


Henry W. Coe State Park is great for stargazing. Away from light pollution and with many exposed areas, the park is one of the best destinations in the region to watch the stars.

Whether you are a professional or an amateur, using a telescope or just looking up, the park will not disappoint.

Find out when the next meteor shower is, pack a warm drink, and head for the hills. The perfect night out.

Final Thoughts

Henry W. Coe State Park has many activities to offer its visitors. Over 200 miles of trails, countless peaks, ponds, and creeks are waiting to be explored.
