What to expect
Shihui waterfall is a specific visitor site for which MINCETUR describes access through Juanjuí, Huicungo and the Churo checkpoint. This provides a starting point for arranging a suitable journey, not permission to explore the whole park. Archaeological Gran Pajatén is not automatically part of that outing.
How it fits into a journey
Plan through Juanjuí/Huicungo with separate travel time and overnight arrangements. This is not a spare afternoon on the Tarapoto–Moyobamba route.
