We drove from our fantastic Bed and Breakfast in Ashland, WI (The Inn at Timber Cove http://www.innattimbercove.com) through Bayfield to visit the Apostle Island Sea Caves (http://www.nps.gov/apis/mainland-caves-winter.htm).
It was incredibly cold and windy, but we persevered to see the caves (open for the first time in five years!). The key is to arrive before noon to park (face out), don't drink much water (no place to pee out there!), and eat a big breakfast (if you stay where we did that won't be a problem!). It is a good mile or more hike to the caves, with beautiful frozen structure to see after the first 1/2 mile. Photo opportunities galore!
Our party slithered through caverns and tunnels, scaled frozen walls and climbed through ice "picture windows" from one side to the other. So glad we went! There is a 2 unit bathroom in the parking lot, and the line took a good 20 minutes to get through (because of all the winter clothes layers, I suppose). The parking was facilitated by the Border Patrol, and they were very friendly and helpful. There is a parking fee (based on the size of your vehicle) of about $5.00. Snow shoes were not useful, and many people who did wear them took them off and carried them. Highly recommend a pair of "YakTrax", at least put one on per person for traction on the slippery spots. Some people pulled plastic sleds with extra gear (a good idea).
I can't wait to visit in the summer and see them from a kayak!
