First of all, the park is BEAUTIFUL! There are many sights to see beyond the lighthouse. We enjoyed geocaching, hiking and pebble beach (the kids FAVORITE!). The sites are hike in only, with pit toilets, which was a little harder with small children but definitely worth the extra hassle for families. Hike out the lake by the pump house to see the lighthouse from the lake without paying to go in it (you can't get anywhere near the lighthouse without a separate fee). That is about as much of the lighthouse my kids cared to see anyways. They would have spend all day at pebble beach throwing the large smooth stones into the lake while enjoying the view of Ellingsen Island. This park is a must hit at least once!
