Campsites at Porcupine Flat Campground (2026 Guide)

Porcupine Flat Campground opens for a short season each year - usually from mid-July through early October, depending entirely on when the Tioga Road clears of snow. At 8,100 feet, this is high-country camping, and the calendar reflects that. With 52 sites (most of them tent-only), it's one of the smaller established campgrounds in Yosemite, and it offers a different experience than the crowded valley floor. You trade convenience for quiet, and you should plan accordingly.

If you're new to camping in this part of the park, start with the complete visitor guide for Porcupine Flat, which covers reservations, packing lists, and seasonal logistics. For an overview of where Porcupine Flat fits among other options, see the all campgrounds page.

Location and Access

Porcupine Flat sits off the Tioga Road about 30 minutes west of Tuolumne Meadows and a good hour from Yosemite Valley. The Tioga Road itself is a scenic drive - 46 miles from Crane Flat to Tioga Pass - but it's narrow and winding. RVs and trailers are not recommended here. The campground road is unpaved and can be rough in spots. Most visitors arrive in passenger cars or small vans.

The nearest services are in Tuolumne Meadows (limited gas and a store) or back in Yosemite Valley. There is nothing at Porcupine Flat - no store, no gas pump, no ranger station. You pack in everything you need.

Tioga Road Status (2026)

As of early 2026, the Tioga Road is still closed for the winter due to snow. Typically it opens by late May or June, but exact dates vary with snowfall. The campground itself won't open until the road is clear and seasonal facility work is complete. Check the park's road conditions hotline (209/372-0200, then 1, then 1) before planning your trip. Don't assume the road is open just because it's July.

Campsites and Reservations

Porcupine Flat has 52 sites, with 48 tent-only and a few that can accommodate small trailers or vans (though the park advises against RVs). Each site includes a fire ring, a picnic table, and a food storage locker. There are no hookups.

What you won't find:

• Flush toilets or running water (vault toilets only)
• Showers or dump stations
• Electric hookups or Wi-Fi
• A camp store or firewood sales

Site Selection

Sites are first-come, first-served within the reservation system, meaning you pick a specific site number when you book. The campground loops are small and close together. Sites near the creek offer some ambient sound and slightly cooler temperatures. Sites closer to the road get more dust and noise. There isn't much privacy between sites, so expect a community feel.

Returning visitors often request sites along the outer edge of the loops for a bit more space. The campground hosts (when present) can help with site issues, but don't count on much flexibility.

What to Expect: The Experience

This is a primitive campground in the truest sense. You are here because you want to be away from the crowds, not because you want amenities. The elevation means cold nights even in August - expect lows in the 40s (Fahrenheit). Afternoon thunderstorms are common in the Sierra Nevada; have a plan for rain.

The biggest challenge for most visitors is the remoteness. If you forget something, it's a 45-minute drive back to Tuolumne Meadows and over an hour to Yosemite Valley. There is no phone signal to call for help. The parking situation here is straightforward - one vehicle per site, no overflow lot.

Porcupine Creek Trailhead

Just a short walk from the campground, the Porcupine Creek Trailhead provides access to the Yosemite Wilderness. This is a lightly used trail that connects to the North Dome and Yosemite Creek areas. The trail itself is steep and rocky in places; the elevation gain is worth it for the views of Half Dome from a less-crowded angle. Most visitors underestimate the difficulty of this hike - it starts high and climbs higher. Bring plenty of water and sun protection.

Nearby Alternatives

If Porcupine Flat is full or doesn't suit your needs, there are other campgrounds along Tioga Road:

• Tamarack Flat Campground - 52 sites, $24, located east of Crane Flat, similar primitive setup
• Crane Flat Campground - larger, with flush toilets and drinking water, closer to services
• Tuolumne Meadows Campground - 315 sites, $36, Yosemite's largest, with more amenities but also more noise

For a completely different experience, the valley floor campgrounds (Upper Pines, Lower Pines, North Pines) offer convenience but charge $36 and book out months in advance. Porcupine Flat's main draw is its quiet location and lower price.

Practical Takeaways

1. Reserve your site as early as possible. Porcupine Flat fills quickly, especially for July and August dates. Check recreation.gov.
2. Bring all water or a reliable filter. Porcupine Creek is the only source. Treat everything.
3. Pack for cold nights and afternoon storms. Layers and a waterproof shell are non-negotiable.
4. No services for miles. Fuel, food, ice - get it before you leave the valley.
5. Respect food storage rules. Bear lockers are provided; use them for all food, trash, and scented items.
6. Check Tioga Road conditions. Don't assume it's open. Call ahead.

Final Thoughts

Porcupine Flat Campground isn't for everyone. If you need flush toilets, a camp store, or phone service, look elsewhere. But if you want a quiet basecamp for exploring the high country - and you're willing to haul your own water and pack out your trash - this is one of the better options in Yosemite. The trade-off is real: you give up convenience, but you gain the sound of wind through pine needles at 8,100 feet and a night sky that doesn't have competition from artificial light.

Plan ahead, pack smart, and you'll have a campsite that most visitors drive right past. That's the point.
