Surrounded by the San Bernardino Mountains and the San Bernardino National Forest, Big Bear Lake in California is a great place to spend a summer vacation rental with a pool. This small city is often confused to be the same as Big Bear City located close by, but the only similarities they share is a name. An amazing overview of Butler Peak allows glampers to have a clear view of the Big Bear Valley on a warm summer’s day. The warmest month to head near the Big Bear Lake City is in July when the average temperatures reach 70 degrees Fahrenheit. Since the summertime allows for warmer temperatures, a relaxing dip in the private pool of a vacation rental while overlooking the San Bernardino Mountains is certainly a must-do activity!
