I do not know . I did see an admin office located next to the gardens you might try calling them to see what they offer.

No, it is not possible to sleep inside, unless you just want to sit on a bench under a tree for a quick nap.

The Botanical Garden is quite large, and I you want to explore it thoroughly, I would recommend a half-day visit or even a whole day visit if you are very keen on plants. The SRF gardens are not very large, and assuming you don't want to sit and meditate there or just sit and absorb the vibes, I would not think you would need more than an hour or two there to explore.

There is no charge to visit the gardens. As for the best time of year, I have been there in October as well as January and February. Each time I have visited, there have been flowers in bloom. Much care goes into maintaining the gardens. Donations are appreciated. I hope that helps.

It's closed on Mondays. If you Google 'SRF meditation gardens opening hours' you'll get a link to the website with the opening hours for the gardens. There is a retreat center attached to it, but you have to be a member of SRF to join the retreats. There is a reception at the bottom of the gardens where you can get more information. Enjoy!

There are weekend retreats available, as long as you are a member of Self-Realization Fellowship you can attend the retreats. They also have wonderful services in a temple a block away. If you Google 'SRF temple Encinitas' the details will come up :)

Not sure about the hours. But we went there around 10am and I know they close at 5pm. It's right off 101/coast highway. Beside Swamis beach. Just key in the address in your gps and it will take you there. 😉

No dogs are allowed in the gardens

Yes, I have seen many children on the grounds over the years. Please be aware that it is a place at which people are asked to be quiet. So no crying, running, screaming .... people want to meditate.
