We visited first week of July when the elephant seals were molting or changing skin. We didn't join any tour, but we stayed in Costanoa camp and lodging which is only few miles away. The seals were moving slowly and basking under the sun, though I think they are probably more active during mating season when the bulls, or male elephant seals, establish themselves among the others.
We saw probably 10 of them from the first lookout. The volunteer guides were helpful and friendly. Be ready to walk about 2 miles. Toilets are located at the museum at the beginning of the trail.
