Are you tired of your typical RV Resort lined up row after row with crappy gravel sites with no trees or greenspace in between the sites, then Santee Lakes offers a great alternative if you get one of their sites that back onto the stream (Site #186). Yes, all/most of their sites are gravel but the stream sites have some greenspace and trees about them that makes these sites more inviting than the others. Full service sites include power, water, sewer. Wifi is included but it was virtually non-existent for all sites at the back of the resort or near the stream sites but you could tether your cellphone connection on your laptop/tablet if you want to.
As well you can peddle boat on one of the 5 lakes and walk, run or ride a bike around the other lakes. The office staff were exceptional.
You are only minutes away from downtown Santee which has all of your favorite box stores, restaurants and entertainment and is only a 25 minute drive into downtown San Diego close to all of San Diego's large attractions such as the San Diego Zoo, Coronado, Sea Word etc.
Bottom line, I just liked this resort far better than any of the other resorts closer in to San Diego outside of maybe the KOA San Diego, Bernardo Shores RV in Imperial Beach and Chula Vista RV Resort in Chula Vista. Stay away from any of the Sunland Resort properties as they all border on the freeway and are extremely noisy and pricey not to mention their attitude is they think they're quite something which they're not.
I hope that helps...
