Snoqualmie Region
This region is a popular gateway to the Cascades and boasts a variety of trails that welcome dogs.
- Rattlesnake Ledge: This wide, well-maintained trail is a consistent favorite for dog owners, though it can get very busy. A report from July 17, 2026, noted the parking lot was full by late morning, so an early start is recommended, especially on weekends. Be prepared for crowds; a July 3 report mentioned seeing over 50 dogs on a single day.
- Snow Lake: Offering beautiful alpine scenery, Snow Lake is accessible for dogs, though a report from July 29, 2026, mentioned a washout under a staircase about a mile up that might require extra caution with smaller dogs. Arriving before 9:00 AM on weekends, as noted in a July 5 report, is wise as the Alpental parking lot fills quickly.
- Talapus and Olallie Lakes: These lakes provide a great destination for a hike with your dog. A July 31, 2026, report mentioned the water was warm enough for a swim at Talapus Lake, a definite plus for active pups. Be aware of potential overnight hiker activity, as indicated by a lost tent report from July 28.
- Annette Lake: This trail offers a rewarding lake destination. While doable with dogs, a July 31, 2026, report pointed out that the many large steps might be challenging for shorter-legged breeds. The lake itself was reported as bug-free on that date.
- Granite Creek Trail to Granite Lakes: This trail leads to picturesque lakes and is great for a dog excursion. A report from August 1, 2026, highlighted blooming wildflowers and berry bushes along the trail, making for a scenic, green tunnel experience.
- Little Si: A shorter, more accessible option, Little Si is popular with dog owners. A report from June 28, 2026, noted it was moderately busy with friendly dogs on leash. Parking can be an issue; a May 30, 2026, report mentioned the main lot was full by mid-morning, with overflow parking available.

- Lake 22: A beautiful lake destination, Lake 22 is a popular spot. A July 31, 2026, report highlighted successfully finding a parking spot by arriving at 8:30 AM on a busy day. Even on a Wednesday, as noted in an July 22 report, the parking lot was 3/4 full by 8:00 AM.

- Lake Serene: While a beautiful hike, this trail presents some challenges. A July 31, 2026, report advised bringing hiking poles due to numerous boulder steps and roots. Be aware that reports, like one from March 7, 2026, have mentioned wash-outs and muddy sections.

Be aware that as of a July 25 report, the area around Goat Lake can be very popular with backpackers, so finding secluded spots might require hiking further.
Planning Tips
- Leash Laws: Always check local regulations regarding leash requirements before you go. Most trails in Washington State Parks and National Forests require dogs to be on a leash no longer than 6 feet.
- Paw Protection: Hot pavement, rocky terrain, and sand can be tough on your dog's paws. Consider dog booties or paw balm if you're tackling longer or rougher hikes.
- Water & Waste Bags: Carry plenty of water for both you and your dog, and always pack out all waste. Hydration is crucial, especially on warmer days.
- Trail Etiquette: Be mindful of other hikers, especially those with children or those who may be uncomfortable around dogs. Keep your dog under control and respond promptly to commands.
