Sharks in Lake Tahoe? Card Sharks maybe, although you may see other aquatic species in the crystalline clear waters of Lake Tahoe. Sand Harbor State Park located on the northeast shore of the lake offers both comfortable water and air temperatures this time of year, making it a perfect swim venue. The 1-mile swim will start at the beach next to the boat ramp, swim out through the unique rock formations and finish at the south end of the park’s Main Beach. This swim is particularly special, as it takes place at the most stunningly beautiful, boulder-strewn area of Lake Tahoe. The event is limited to 300 participants, so don’t wait to register!
PLEASE NOTE: This swim is not for novices. This event is for experienced open-water swimmers only. You should be able to swim one mile comfortably in a pool in under 40 minutes.
