Camping on Angel Island is going to get a lot more comfortable — it’s just not clear when. The parks commission worked with graduate students from California State Polytechnic University, Pomona, who drew up plans for 13 wedge-shaped cabins. The units will not be set up for electricity or heat and won’t include stoves but will be ADA compliant. Currently, camping is allowed on the island, with a kayak-in site and 10 basic sites, yet with no substantial structures to shelter visitors on foggy wet days. Plans are not finalized and officials are unsure how many cabins will ultimately be built by concessionaires. For some concrete details, here are the numbers.
