Diane & I set out on a cross-country RV trip on June 29, 2018. The first destination of note was Lassen Volcanic Park in CA. We camped to the north of the park at Hat Creek Hereford Ranch & RV Park which is situated about midway between the park and the waterfall. The latter is lovely to see, of course, but it also offers a cooling respite on hot summer days as the canyon below the falls remains naturally chilled. Despite some trail closures in McArthur-Burney State Park we were able to enjoy a short hike that encircled the falls. Note that parking at the falls is limited and it can be difficult or impossible to get in to see them. Choosing your arrival time can make all the difference. Admission was $10 per car when we were there, $9 for seniors. See their web page formore information.
