George J. Hatfield SRA
Hatfield is a flat, grass and forest-covered riverside campground, located on the Merced river about 90 minutes souteast of San Jose (off I5, either north of Pacheco pass or south of Tracy). The riparian setting is perfect for fishing or small boating (canoes are great here). There's a few beaches which we used as launch points, but no formal boat ramps that I saw. The water depth we had in September averaged between our knees and waists - perfect for play, especially witih kids and dogs. The park was very dog-friendly, especially Ranger Becky who carried duck-jerky dog treats, and did not give us too much grief about letting our well-behaved and trained dogs off-leash. It was also not crowded at the time of year we went, even on the weekend. However, there was much trash left behind by previous campers and picnicers. Good amenities, bathrooms (no showers that I saw), and a great group picnic and camp area with large grill areas, plenty of picnic tables, and electric light posts. We were looking for something out of our usual routine and local - we weren't dissappointed and had a great time, I recommend this site, and I look forward to going back again. It's similar to Del Valle, but not as big and without the mountains.
