Great! Here are a few ideas that could be meaningful for your friend:
1. A National Parks pass: Your friend will really love using it to explore all the national parks around the US.
2. A custom painting of a national park: Based on your friend's favorite hiking location, you could commission a local artist to paint it so that it becomes a cherished memento of the unforgettable experience.
3. Outdoor gear: A pair of hiking boots or backpack is an essential element when hiking in national parks. A long-lasting and durable gear will come in handy while hiking.
4. Personalized hiking map: A personalized hiking map could be a great addition to your friend's hiking essentials. A map inscribed with your friend's name, date of hike, and the park name could be something unique.
5. National Park book: Your friend will love reading about the parks they have visited and learning more about the parks they have yet to explore. A book about national parks could be an informative and thoughtful gift.
