Near a tree is magnificent for meditations. But it depends what you are searching for. Caves are good for opening third eye/senses and abilities… also meeting some beings that are not from this world. Trees gives opportunity to communicate better with higher realms and to feel easier the interconnection of everything.
Animals behave very well when someone is in this type of state. Big ones are watching and observing you as they can sense and feel that you are part of them, which is true, but then they feel it and don’t feel scared. For whole time had just one insect on me, but in this time I had activated some clearings on me haha
For food had most of days vegetables, fruits, nuts, but near me had also one house where people are making retreats, so I had also other more lower vibrational meals.
Had 2 days in which had very little water, but it’s not a big deal as I make 3-4 times in the year dry fasts.
I Did a lot of walking and breathworking that was exhausting the physical body at maximum, as the mind – and meditations were easily made with hours.
Recharged my batteries and also reached some higher levels of consciousness which will create a reflection and make fields even stronger.
Watched many things for the near future with the vaccines and those things and I didn’t like the picture much. Around September I saw new big lockdowns throughout the world. Hope i didn’t see right or this timeline to change. 
People who are not in the big towns will be better in this period of time.
Also, soon the people will have a lot more technologies and information for zero-point, free electricity, water, more ecological stuff, but this will be maybe in 2-3 years.
