Tours On and In the Water
You will note that a visit to San Diego wouldn’t be complete without a guided tour by means of the Pacific Ocean to explore the breathtaking views. Excursions can take place via yacht, sail boat, former Navy SEAL RIB boat, catamaran, jet ski, kayak, snorkel, kayak/bike combo, and even on a stand-up paddle board. San Diego Harbor cruises combined with dinner or Sunday brunch are also a popular choice. You can enjoy these within a normal time span of 1 and 3 hours and include all necessary equipment, as well as well-trained and knowledgeable guides. One activity locals and visitors truly enjoy is whale watching along the trip with the promptcharters.com
Biking Tours
You can also opt for taking a bike tour of San Diego. Choose from road bike rides through La Jolla, Mission Bay, Coronado and downtown San Diego or off-road mountain bike rides in San Diego’s North County. The popular La Jolla “Plunge” or “Freefall” trip starts at the top of Mt. Soledad with the downhill ride into La Jolla and the surrounding coastline. Options also include electric bikes as well.
