Yosemite is one of the best National Parks in America. We went during the month of August and most of the waterfalls are dried up by this time. But you can still enjoy the grandeur of the iconic views of El Capitan, Sentinel Dome, and Half Dome as well as taking a swim or jumping into the Merced river.
When traveling to Yosemite we stayed at the Pines Resort at Bass Lake in California. This cabin style lodging is located adjacent to the lake and has kitchen, living room, and balcony among some of their accommodations.
The lake has fishing and swimming and an assortment of watersports. We rented a couple of jet skis at the Bass Lake Boat Rentals and Watersports. I would highly recommend making reservations in advance as same day rentals can be very difficult during summer season.
