We arrived around 8:30 am. There was a park employee near the entrance that described each hike option. We chose the botanical hike which is the longest I believe and the employee reminded us to make sure that everyone had good shoes for hiking, enough water per person (at least 1.5 liters which we really drank) and sunscreen. If the weather is hot, I definitely wouldn't start later than 8:30/9:00am. It had great views and was somewhat challenging but not too bad. We had fun and appreciated the sections that had occasional shade as well as the occasional flowers scattered throughout. Unfortunately we were too tired to do the cave hike as well so we'll have to go back another time to do that one.
