Mount Hamilton rises to 4,265 feet in California's Diablo Range, with temperature fluctuations of up to 30°F between day and night during summer months. The area sits at the intersection of coastal and inland climate zones, creating variable conditions for campers. RV camping options range from developed county parks to full-service private RV resorts, most requiring reservations during peak season from May through September.
What to do
Hiking trails access: Joseph D. Grant County Park offers extensive hiking opportunities through oak woodland and grassland habitat. "The hiking is quite beautiful and the woodpeckers were busy storing acorns," noted one visitor who appreciated the wildlife viewing opportunities during November.
Steam train excursions: Several campgrounds provide convenient access to the Roaring Camp Railroad. At Smithwoods RV Park, campers enjoy proximity to this historic attraction. "We could hear the train whistle in the daytime coming from Roaring Camp Railroad. This location isn't too far from Santa Cruz and Felton if you want to go into town and do activities," a reviewer mentioned.
Swimming options: During warmer months, Cotillion Gardens RV Park offers a pool for cooling off. "I loved this campsite! Plenty of trees for shade, there's a pool, hiking trails, a little river. So beautiful and peaceful here," reports one camper who enjoyed the recreational amenities.
What campers like
Redwood surroundings: The mature redwood forests create distinctive camping environments. At Santa Cruz Redwoods RV Resort, a visitor observed, "The campground is covered entirely by redwoods with plenty of shade for a cool vacation. Spots were leveled with dirt."
River access: Several campgrounds feature water features that enhance the camping experience. "We had a great view of the San Lorenzo River and Henry Cowell State Park," wrote a camper at Smithwoods RV Park, highlighting the scenic benefits of waterfront sites.
Wildlife viewing: Natural areas around Mount Hamilton support diverse wildlife. "We stayed a nice spot. No one else was in the campground, so it was definitely quiet... saw a lot of bunnies and a bobcat on the way out," reported a visitor to Joseph D. Grant County Park.
What you should know
Site spacing varies: While some RV parks offer spacious sites, others place rigs closer together. At Thousand Trails Morgan Hill, a camper noted, "Sites are not level," indicating preparation may be needed for a comfortable stay.
WiFi and connectivity challenges: Digital connectivity varies significantly by location. At Cotillion Gardens RV Park, a visitor reported, "No cell service but good WiFi if you're close to the office," indicating campers should prepare for limited communications.
Reservation timing: Popular campgrounds fill quickly during peak seasons. "Reservations are strongly recommended during peak travel seasons, especially summer weekends when Bay Area residents seek cooler temperatures in the mountains," advises a veteran camper.
Tips for camping with families
Activity options: Multiple recreation opportunities keep children entertained. At Casa de Fruta RV Orchard Resort, a visitor appreciated that there was "perfect place to stop! Lots to see & do with the Casa de Fruta fruit stand, Wine & Deli stand, Burrito & Taco stand... Peacocks running around add a whole new dimension, lol! The asphalt Campground was great for the kids biking."
Pool access: Swimming pools provide valuable family recreation. One camper at Thousand Trails Morgan Hill mentioned, "The kids loved the resident cats. The pool was huge and well loved. Lots of recreation."
Recreation centers: Onsite facilities enhance family camping experiences. A family staying at Cotillion Gardens RV Park appreciated that "there is a large clubhouse with foosball, ping pong and arcade games which is open from 9am - 9pm. My daughters used the clubhouse while I set up camp and after waking up while I stayed in bed for a little while."
Tips from RVers
Leveling requirements: Site conditions vary across RV parks. One RVer at Santa Cruz Redwoods RV Resort advised, "I had to use a 6 foot extension on the sewer hose. Shore chord was fine as was the water spigot," highlighting the need to prepare appropriate equipment.
Winter camping considerations: Seasonal changes affect camping conditions. At Kit Fox RV Park, a winter visitor found, "We used Kit Fox as a stop over on our voyage from Oregon to Arizona. We stayed one night. The park is CLEAN, Quiet, the sites level, The Park staff are helpful," suggesting this can be a reliable year-round option.
Shopping convenience: Several RV parks offer proximity to necessary supplies. At Gilroy Garlic USA RV Park, a reviewer appreciated that "shopping and pharmacy are walking distance. Many California activities are less than an hour away," making it convenient for extended stays.
