Hiking around in nature whilst on LSD, Mushrooms, MDMA, MDA, probably the 2C family as well are all good ideas. Just as long as you don't overdue it, have some snacks and back pack filled with water.
Best time ever was up in Maine, mushrooms with my cousins. Brilliant hike in late June simple afternoon, saw a moose, we were all mesmerized by it. Nature paths galore near my fams Cabin up that way. No nervs about getting lost cause by cousins know that area like the back of their hands. Awsome time, even ran into 2 other hippy hikers who we smoked a bowl or two with and then went our separate ways.
Make no mistake about it Maine may be the first east coast state to legalize marijuana for recreational use, fairly progressive state but I digress,
Even though suburbia, and even the city are not filled with the peace of nature I had many awesome times walking around in the city and it the burbs on E. MDMA tweeks your vision just a lil bit so things won't look as increadible but the euphoria and energy buzz that hits you makes everything around you great, never actually hiked on MDMA but I could see how great it would be.
Stick to the classics, mushrooms, LSD,
