Earth Day lands on April 22 this year, and we think the best way to mark it is exactly the way we mark most days at DogTrekker — out on a California trail with a happy dog. The twist for Earth Day 2026 is a little extra intention: pack a spare trash bag, pick up after other hikers who didn’t, and pick parks where our leash etiquette and trash discipline genuinely make a difference.
These five dog-friendly spots span the state, and each one rewards a slower, more careful visit.
1. Fort Funston, San Francisco
Perched on a 200-foot windswept bluff at the western edge of the city, Fort Funston is one of the most beloved dog destinations in the Bay Area. It’s part of the Golden Gate National Recreation Area, and the cliffs double as sensitive wildlife habitat. Hang gliders share the sky overhead. Stay on signed trails, skip the dune crossings, pack out what you pack in — and, if you’re feeling extra Earth-Day-ish, grab somebody else’s trash on the way back to the car.
2. Point Isabel Regional Park, Richmond
The East Bay Regional Park District runs Point Isabel, a 23-acre landscaped shoreline with views stretching across the bay to the Golden Gate and Marin. It’s a community favorite and one of the largest purpose-built dog areas in the country. The district runs stewardship events across its network all spring — a strong option if you’d rather cap your walk with a volunteer hour than just a coffee.
3. Lake Chabot Regional Park, Castro Valley
Another East Bay gem, Lake Chabot wraps around a 315-acre reservoir built in the 1870s and now ringed by miles of walking and hiking trails. Mid-April is the sweet spot: the hills are still green, the wildflowers are still hanging on, and the early-morning fog burns off by mid-morning. Leash up, stay on trail, and leave the flora where it is.
4. Huddart Park, Woodside
On the San Francisco Peninsula, Huddart Park winds through second-growth redwoods and madrone forest above the town of Woodside. Redwood root systems are more fragile than they look — sticking to the marked trails is the whole game here. The park is managed by San Mateo County Parks, which regularly hosts Earth Day volunteer days worth checking before you head down.
5. Crystal Cove State Park, Laguna Beach
If you’re south, Crystal Cove State Park delivers ocean bluffs, coastal sage, and one of the most photogenic stretches of the Orange County coast. California State Parks sets specific rules about where dogs can and can’t go inside each park — read the signage at the trailhead, stick to the paved and designated paths, and you’ll bank one of the best sunset payoffs in Southern California.
A short leave-no-trace checklist for dog people
Whichever park you pick this week, the drill is the same: leash where required, stay on trail, pack out every bit of waste (yes, bagged waste counts — please don’t leave it trailside), give wildlife a wide berth, and keep the volume down. If you’re new to the idea or want a refresher, our Leave Only Paw Prints® values page is a good 90-second read. The official Earth Day 2026 campaign also has a searchable event map if you want to plug into something local.
