Tips for camping with families

Wildlife education: Turn animal sightings into learning experiences. "Saw a lot of bunnies and a bobcat on the way out," reports Melissa S. from Thousand Trails San Benito, showcasing potential wildlife encounters that can engage children.
Temperature preparation: Pack appropriate clothing for temperature swings. "I'm not going to hold the chill against this area because I didn't dress accordingly," Sophie S. admits, highlighting the importance of layered clothing for comfort.
Visit during spring: Springtime offers milder temperatures and more visible wildlife. "We just visited this campground with some friends... Deer wandered through camp at all times of the day," Butch C. shares about his experience during an optimal season for family visits.
Tips from RVers
Site selection for horse trailers: Choose campsites that accommodate larger vehicles. "Big campground with a pool although a hot tub would be nice also. The sites are a little small but very mature trees and they keep it clean," notes Ben V. about a similar regional campground with RV accommodations.
Water and hookup availability: Check which amenities are available at specific sites. "Our site was shady enough, though not all sites appeared so lucky," Patricia O. advises, indicating variability between sites that may affect RV comfort levels.
Road access considerations: Be prepared for narrow mountain roads. "From main road it takes about 35 min drive up the hill through narrow road which is paved but I don't think it is appropriate for RVs," cautions Lady L. about a similar park in the region, suggesting careful route planning for larger vehicles.
