Went to the park early afternoon, the hike to turtle beach took us 1 and 3/4 hours with a few stops to rest here and there (we are not very fit). We thought we could just take a boat back, however arrived on turtle beach and waited for 30 minutes with no boats in sight. With half an hour left before sunset we had to push ourselves to walk as fast as possible before it becomes too dark. The walk back took us 80 minutes, the last 30 minutes lit only by our mobile phone screens. We arrived at the park entrance completely exhausted and glad we came out alive!
