The ride

A trail day around Puddingstone.

Choose Bonelli for a different kind of bicycle and a different day: a mixed-surface loop around the Puddingstone reservoir surroundings. The plan follows designated shared trails with short park-road links, including the western Lower Bee Hive and Vargus connections. It is a mountain-bike outing, not a smooth waterfront cruise or a claim that every lakeside path allows bicycles.

Start at the mapped Bonelli Trail junction on the western side, near the Raging Waters Drive corridor. The GPX begins on the trail, not at the vehicle payment gate. Check the park map for your approach and any entry fees. Most importantly, the county park page currently carries a Monday-and-Tuesday regional-park closure notice: confirm access before travelling and do not bypass a closed entrance.

The loop goes around the northern and eastern trail sections before returning along the southern and western hills. It includes paved park-road connectors, including Raging Waters Drive and McKinley Avenue; it is not entirely traffic-free singletrack. On the dirt sections, expect changing grip and junctions, and be prepared to walk anything that exceeds your ability.

Bicycles share these trails with hikers and horses. Yield, slow well before passing and avoid abrupt approaches. The county network has multiple branches; our measured GPX is one selected loop rather than the full distance of every trail listed on the county page. The gallery shows the reservoir setting and picnic areas, not evidence of current trail surface or an exact lakeshore riding line.

    Back where you began

    Complete the mapped trail and park-road loop. Do not substitute lakeside walking paths for the GPX. The downloaded track includes the return to the start.

Food & a place to pause

Plan your break.

Bring coffee or a snack for a designated picnic area after leaving the trail. The park facilities are useful optional stops, not verified on-track cafes or guaranteed open services.

The county lists picnic and restroom facilities in the park, but not guaranteed availability at every trail junction. Leave the riding line and follow signed access for a break. Carry enough water independently of taps or concessions.

No cafe pin is shown because an exact suitable stop has not been verified. This is a supply-planning limitation, not a claim that no cafes exist nearby.

Puddingstone and the surrounding hills

Puddingstone Reservoir and surrounding hills give the loop its setting. The route uses trails and park-road links, not a continuous waterfront promenade.

The useful details

Plan a little. Enjoy a lot.

Start & finish

Western Bonelli Trail junction near Raging Waters Drive. Use the official park map to plan legal entry and parking.

Bike choice

A mountain bike is the conservative choice. A beach cruiser or narrow-tire rental is not recommended for the mixed-surface loop.

Closure & weather

Check the Monday/Tuesday closure notice and any fire, rain or trail restrictions. Do not ride closed or muddy trails.

Trail margin

Carry water, food and puncture supplies. Riding time varies greatly with skill and surface; allow for walking and give way to other users.

Water, facilities & a place to pause

The county lists picnic and restroom facilities in the park, but not guaranteed availability at every trail junction. Leave the riding line and follow signed access for a break. Carry enough water independently of taps or concessions.

Bring a suitable bike. Our Santa Monica rental comparison does not cover this inland start.

A few things worth knowing

Before you set off.

Is the GPX a recorded ride?

No. It is a planned track assembled from connected OpenStreetMap roads and bicycle-permitted paths. Each file is a full loop or an out-and-back, with named waypoints. We have not field-ridden it or checked same-day closures.

What is included in the distance?

The measured map geometry for one complete described outing, returning to the selected start. Rental-shop approaches, walking detours and extra laps are excluded. GPS devices may calculate a slightly different distance.

Can I use an e-bike?

These guides are for ordinary pedal bicycles. Check the exact bicycle class, local jurisdiction, park rules and posted signs; permissions differ by location and trail. An e-bike rental offer is not proof that a route allows it.

Does a route file prove the way is open?

No. Check the official access links on the guide before leaving. A closure, flood warning or posted restriction overrides the download; never bypass a barrier to follow a track.

What should I bring?

Water, sun protection, a helmet, a lock, a charged phone and the downloaded track. Check brakes and tire pressure. Allow extra time for collecting and returning a rental.
