Yes, we operate rain or shine. If there is lightening on the tour, we will pause and wait for it to pass over. Typically, a lightening storm, will last about 20 minutes and then the sun comes out. Please prepare by wearing non-cotton clothes (dry quicker and keep you warmer) and bring a rain jacket. If you do not have a rain jacket, we sell clear ponchos for $2. The clear poncho is the ONLY piece of clothing allowed over the harness.
