## Getting There, Parking & Hours

Primary access: W Caribbean Drive trailheads between Borregas Ave and Google Pkwy (near 293 W Caribbean Dr). The City lists this as the meeting point for free Baylands birding tours and notes free street parking along Caribbean Drive—follow Bay Trail signs. Tours typically run noon–1 p.m. on the first Wednesday of the month (canceled if raining). Expect herons, egrets, pelicans, hawks, and occasional burrowing owls.

Additional parking option: The City has also identified extra parking at 701 1st Ave (northwest end of Caribbean Dr). Use the guard station, state you’re accessing the Bay Trail, and park only in VISITOR spots as posted. Cleanwater

Baylands Park gate hours & fees (adjacent park): Main entrance at 999 E Caribbean Dr operates 8 a.m. to 30 minutes after sunset; vehicle entry fees apply (this is the city park, not the public street parking). If you need picnic areas, reservable spaces, or a base with amenities, this is your place; the Bay Trail runs right by it. Clara County Parks

## Route Ideas (Out-and-Backs You Can Trust)

1) Sunnyvale Caribbean Dr → Moffett Bay Trail (Easy fitness out-and-back)
Head northwest along the levee toward Moffett Bay Trail; it’s a straightforward, flat cruise with continuous bay views. Portions here run on U.S. Fish & Wildlife Service (FWS) refuge land; dogs are not allowed on the Moffett Bay Trail segment (see “Rules” below). Fish and Wildlife Service

2) Sunnyvale Caribbean Dr → Mountain View connectors
From the Moffett corridor you can continue toward Mountain View via linked Bay Trail segments, extending your run/ride significantly while staying low-stress and off-street. Fish and Wildlife Service

## Birding & Seasonal Highlights

This is a reliable birding corridor. On first-Wednesday lunch tours guided by Santa Clara Valley Audubon volunteers, typical sightings include great blue herons, great egrets, pelicans, red-tailed hawks, and occasional burrowing owls. Winter and spring bring peak shorebird activity around the ponds and sloughs.

## Rules, Dogs & Closures (Read This)

– Bikes: Allowed on Bay Trail and refuge levee trails unless posted otherwise. Persistent URL
– Dogs: The Don Edwards San Francisco Bay National Wildlife Refuge prohibits dogs on most refuge trails. Specifically for the Moffett Bay Trail (the levee north of Caribbean Dr toward Mountain View), dogs are not allowed. Only a handful of trails near the Fremont Visitor Center permit leashed dogs; this does not include Moffett. Plan accordingly if your route uses refuge segments. Fish and Wildlife Service
– Closures: Refuge trails can close for habitat work (e.g., salt pond and slough projects). Check current alerts if you’re chaining longer rides into Alviso/Fremont. Fish and Wildlife Service

## Practical Tips

– Start smart: Use free street parking on Caribbean Dr for quick access, or pay to stage at Baylands Park if you want amenities before/after.
– Wind & sun: It’s exposed; bring layers and sunscreen year-round.
– Tires: Road bikes are fine; gravel sections are generally smooth, but carry a tube/patch kit. (Surface mix confirmed by trail descriptions.)
– Wildlife etiquette: Stay on trail and yield space to resting birds, especially during migration and high-tide roosts. Refuge guidance emphasizes minimizing disturbance. Persistent URL
