There are mainly two types of operators offer excursions sailing the Beagle Channel to visit sea lion colony and lighthouse at the habour. Excursions with small boats (10-25 passengers) are more expensive but simply better than those with big ones (about 70) as it can get closer to the island and offer additional half an hour trek in one of the islands with 360 degree view of the mountain ranges around...very worth taking. Tango (max. 15) is the one I picked. The service was superb and the trip was enjoyable.
